    Postprocessing 3D prints

    Some of you could see it on my Instagram account, but for those who didn't, here are some of the tips if you want a really transparent and water tight models: use Polymaker PolySmooth transparent or Prusament PVB filament. According to Prusa you should set layer height to 0.3mm, but I print with 0.2 mm layer height with very satisfying results. Wall thickness 0.6 (you could make 0.8mm but as thicker it gets, model is less transparent so I didn't go at 0.8mm, maybe once I will try). After the print scrape away some irregularities and after that you can put it in chamber for vapor smoothing with isopropyl alcohol. If you don't own one (as me) just spray the model (inside and outside) with IPA for smoothing results. Don't be aggressive as too much alcohol on the model softens and dissolves PVB so it is better to spray a little bit than after drying, spray it again. Bellow is the example of my aorta model and you can see catheter and guidewire really well.

    I generated this model for cardiosurgical training simulator. I used the Obelix dataset from the Osirix dicom library. Those are the the raw 3d models of the thorax and the heart. I used those to add two mini invasive accesses to the right and a table for pig hearts in the mediastinum with the shape of the diaphragmatic of the heart. I took 2 kg. of PLA and more than 200 hours of print, sliced into 10 separate pieces and glued with cyanacrilate glue. It's quite resilient, the floating ribs are quite breakable and I don't recommend to print them. I'm adding here the raw files, because I don't know what kind of access you need on the thorax. The printed thorax can be covered with vinyl or leather for extra realism. anatomy, thorax, 3d, printing, simulator, chest, .stl, 3d, model, printable, ribs, sternum, cartilage, dorsal, spine, transverse, body, intervertebral, disc, bone, ventricle, auricle, mediastinum

    As one of the most well-known names in the 3D printing industry, Czech-based Prusa Research has built a solid reputation bolstered by the excellent quality of their 3D printers. The open-source model adopted by manufacturer Josef Prusa has helped make the development of these printers a work done by the community. Right now, Prusa sells four 3D printer models, all of which are relatively affordable and highly reviewed. If you want to get in on this action, then here’s a detailed guide on which Prusa 3D printer you should go for, regardless of your level of experience. 1. Original Prusa Mini Price: $349.00 Launch date: Late 2019 Ideal for: Beginners, users with limited space As the name implies, the Original Prusa Mini is a highly compact 3D printer that offers all the best features of the full-sized Prusa models. This is also their entry into the budget market – it costs less than half the price of Prusa’s flagship 3D printer, the Original Prusa I3 MK3S. With its small 380 x 330 mm footprint, the Original Prusa Mini is the perfect 3D printer for those who don’t have a lot of space to work. Of course, this also means that the build volume of the Prusa Mini is fairly limited at 180 x 180 x 180 mm. This is something you’ll have to deal with but all the brilliant design elements we have come to expect from Prusa are there – from the magnetic steel print bed to the colored LCD screen interface. The Prusa Mini comes almost fully disassembled when it ships, so expect to spend between 1 to 2 hours for assembly. A lot of thought has gone into making the assembly instructions as intuitive and easy to follow as possible, so even beginners should find this whole experience fun. To help keep the Prusa Mini small, it comes with a Bowden-style extruder. Much has been said and written about the complications of using a Bowden extruder, and all those pretty much still manifest in the Prusa Mini. With a longer path for the filament to travel, the Bowden Extruder can clog more frequently than you care for. If this happens, you may need to loosen the extruder gear or replace the PTFE lining of the hot end completely to get the filament running again. Aside from that hiccup, the Prusa Mini has elements that make it very beginner-friendly. It ships with the PrusaSlice slicer software which has now been updated with a profile for the Mini. You can run the slicer in Simple mode which only gives the most basic parameters to adjust, or you can switch over to Expert mode for more customization options. Loading of files into the Prusa Mini can be done either via a USB cable or online through the printer’s Ethernet port. The color LCD screen of the Prusa Mini is also a very useful tool for starting up and monitoring the status of the project. At the onset, the screen displays the estimated time it will take for the project to finish and how much filament it will consume. The display then updates as printing progresses to show the total elapsed time. One of the best features of the Prusa Mini (and other Prusa printers) is the removable magnetic print bed. Not only can the bed be heated up to 100 C, but it has also been coated with PEI to help with bed adhesion and can be easily popped off the printer to facilitate removal of your finished print. It works great in most cases, although the temperature limitation of the bed can be problematic in some cases. According to Prusa, the Mini can work with a selection of filament materials that include PLA, ABS, PETG, ASA, and ABS. The maximum temperature that the extruder can reach is 280 C, which should theoretically be hot enough to print with Nylon. However, warping can be a problem because of the limited bed temperature. If you’re planning on printing with Nylon or ABS, it would be a good idea to use a DIY enclosure. The Prusa Mini lacks an empty filament sensor (only available as an optional upgrade) or any print resume function. This is presumably a move to help keep the price of the printer down and is not a deal-breaker in any way. Overall, the Original Prusa Mini is a compelling product for those who want to get into 3D printing but aren’t willing to spend $500 to $1000 on their first 3D printer. Prusa seems to have designed the Mini specifically to be beginner-friendly with the level of care and quality that we have come to expect from the brand. 2. Original Prusa i3 MK3S Price: $749.00 (kit) or $999.00 (assembled) Launch date: Early 2020 Ideal for: Experienced users The flagship of the Prusa brand, the i3 MK3S is Prusa’s follow-up to the award-winning MK2S printer. Even with lofty expectations, the i3 MK3S has managed to impress just about every industry expert and has been repeatedly declared as the best 3D printer of 2020 by several review sites. Simply put, this 3D printer benefits from all the lessons learned from the other Prusa models that came before it. It features improvements in the empty filament sensor, extruder design, and slicer software. Combined with the old and reliable features, the i3 MK3S is simply described as a 3D printer that works without being too complicated to use. The beefier i3 MK3S can accommodate a maximum build volume of 250 x 210 x 200 mm, which should be enough for all but the exceptionally large 3D printing projects. As with previous iterations, its printhead is mounted on rails that allow movement in both the X-axis and Z-axis, while the print bed is free to move along the Y-axis. This design helps with rigidity and eases the movement requirement of the print bed, allowing for printing that is more precise, faster, and quieter. The i3 MK3S uses a direct extruder which has been redesigned with two extruder gears. This makes the handling of all filament types, including flexible ones, less problematic. The extruder has also been redesigned to allow access and replacement of the PTFE tubing without having to take apart the entire extruder assembly. The magnetic PEI-coated print bed is back in the i3 MK3S. This time, Prusa offers both a smooth PEI sheet and a textured PEI sheet for better adhesion. The bed temperature can reach a maximum of 120 C, while the hot end temperature can be heated up to 200 C. At these temperatures, printing with filaments like Nylon, ABS, or Polycarbonate should no longer be a problem, although you might still need an enclosure. An all-metal hot end contributes as well to making the i3 MK3S as versatile as possible in terms of filament compatibility. The Prusa i3 MK3S is a fairly “smart” 3D printer. It comes with an automatic bed leveling feature and has a “Power Panic” mode which kicks in if there is a loss of power. Once the printer detects a power interruption, it shuts down all heating systems and saves the status of the current print job so you can pick up right where you left off when the power comes back. The i3 MK3S comes with the Prusa Slic3r, a slicer software that is powerful yet intuitive and easy to use. This version of the slicer has been upgraded with more profile options, easily allowing users to swap between “Speed” and “Quality” modes. The Prusa i3 MK3S isn’t exactly cheap, but it’s easily one of the most reliable, yet easy to use, 3D printers available right now. The various quality-of-life improvements that Prusa has made with this 3D printer has rounded it out into one of the best they have ever developed. Prusa also offers top-notch customer service should you run into any problems. This printer is highly recommended for users with a moderate level of experience who are considering offering commercial 3D printing services. 3. Original Prusa i3 Multi Material 2S Upgrade Kit Price: $299 IDEAL FOR: Long-time owners of the Prusa i3 MK3S This is not a separate 3D printer but is instead just an upgrade to the Original Prusa i3 MK3S. The technology has been around for a couple of years but has now been updated to its best version in the MMU2S. This kit is also compatible with the MK2.5 and MK3 versions of the Prusa i3 printers. Like the older versions, the MMU2S is designed to handle switching between up to five different filaments. It’s basically a print head replacement for the Prusa i3 MK3S, although saying it that way may be understating just how complex the setup can be. Assembly of the MMU2S is just slightly more complicated than the assembly of the MK3S printer itself, in case you ordered it as a kit. Thus, we recommend getting familiar with the components of your 3D printer before going ahead and ordering this upgrade. Prusa has made a lot of improvements in this version of the Multi Material upgrade. It now has a direct extruder (instead of Bowden) and just a single PTFE tube to lead the selected filament into the extruder. It also benefits from the new hybrid mechanical-optical filament sensor of the i3 MK3S, as well as its Bondtech double extruder gears. The MMU2S kit comes with an external filament buffer which helps prevent filament entanglement and makes it so much easier to position the five filament spools relative to the printer. It seamlessly integrates into the smart systems of the i3 MK3S and can also detect and recover from power loss. The standard Prusa Slic3r software supports the MMU2S upgrade with its various wipe features. To save on filament and time, you can choose to either wipe excess filament into the infill, into an object, or simply have a Smart Wipe Tower. This allows for a clean changeover from one filament to another while minimizing filament waste. One only needs to look at Prusa’s showcase of prints made using their MMU2S upgrade to realize the potential of this add-on. It requires a step-up in terms of technical skill to fully utilize its potential, but this is an upgrade worth considering for anyone who has spent time with their Prusa i3 printers. 4. Original Prusa SL1 Price: $1399 (kit), $1699 (assembled) Launch date: Early 2019 IDEAL FOR: Professional and commercial users Prusa has managed to build a pretty solid reputation with their FDM printers, so it really was only a matter of time before they delved into SLA printing. The SL1 represents their initial effort and was only made possible by acquiring Futur3D, a company with five years of experience with the technology. Overall, the SL1 was great for an initial product but isn’t quite there yet compared to more developed SLA printers. The Prusa SL1 strives to be a cut above the budget SLA printers but still at a relatively affordable price. The premium feel is apparent in the SL1’s build quality and a well-thought-out interface that features one of the first Prusa printers to come with an LCD interface. If you order the kit version of the Prusa SL1, then be prepared to spend the better part of the next one or two days to put it together. There is a whole array of panels, circuit boards, and wires to assemble which fortunately is made easier by the detailed instructions written up by Prusa. This makes it sound a little more complex than it actually is – it’s not terribly technical, just time-consuming. More specifically, the Prusa SL1 is an MSLA, or masked SLA, 3D printer. What this means is that the SL1 shines UV light through a mask to cure an entire layer of photosensitive resin simultaneously. This is in contrast with traditional SLA printers that use a beam to cure the resin one point at a time. Using the 5.5-inch 2K LED screen, the Prusa SLI1 improves on the throughput of a traditional SLA 3D printer. Another characteristic that makes the Prusa SL1 unique from other SLA printers is the way that the resin vat tilts ever so slightly once a layer has been completed. This reduces the vertical force needed to separate the finished print from the bottom of the resin tank. For reference, the Prusa SL1 is a bottom-up printer with a transparent build plate that moves up as the print progresses. In terms of print quality, the Prusa SL1 performs as excellently as just about any high-quality SLA printer. It can reproduce details at a much finer level and produces prints with layer lines that are barely visible. The 405-nm wavelength of the SL1’s UV light made it compatible with a wide selection of third-party photopolymer resins, although you may have to play around with exposure time settings. The Prusa SL1 also comes with the signature Pruca Slic3r software, which has been updated for SLA slicing. The software is fairly easy to use has been updated and improved since the initial launch of the Prusa SL1. Prusa also sells the Original Prusa Curing and Washing Machine (CW1) as an add-on for the SL1. This is an all-around processing tool fo SLA prints. The machine has functions for washing of finished prints with isopropyl alcohol, drying, and post-curing UV exposure. This is a great accessory for eliminating the mess and hazard of handling the mixture of isopropyl alcohol and uncured resin. The Original Prusa SL1 is a great option for those who are into commercial 3D printing and need a higher level of detail than what FDM technology can provide. Although there are other SLA printers that are much more expensive, the Prusa SL1 is certainly not cheap – especially if you pair it with the Prusa CW1 post-processing machine. What we know for sure is that Prusa is a stickler for innovation and that we probably have not seen their last stab at SLA printing. Final thoughts The Prusa has managed to maintain a solid reputation in the world of 3D printing by continuously coming up with more and more innovative features for 3D printers. Aside from the fact that the printers are open-source, the company itself takes pride in being cognizant of the needs of their users. This community-driven approach to product development has propelled the Prusa brand to heights that have made them virtually unequaled. It’s hardly surprising that their products routinely win awards and get declared the best 3D printer of the year, every year.

    3D Printing Safety Tips for Kids

    Now that STEM education is being pushed to the forefront, 3D printers are increasingly becoming more common parts of classrooms around the world. This is a welcome development, of course, as 3D printing and other more advanced manufacturing technologies may prove to be vital parts of one’s skill set in the near future. This development presents an important question – how safe are 3D printers for kids? Can teachers leave students to use 3D printers unsupervised? What safety measures can schools and teachers take to ensure that no untoward incidents happen when kids work with 3D printers? The hazards of 3D printing The first step in establishing effective safety practices is to acknowledge that there are inherent hazards to 3D printing. After all, you’re still dealing with a machine with parts that can be heated beyond 200 °C. If you need to teach kids about using 3D printers, then you might as well tell them about the following hazards as well: Moving parts There are a lot of moving parts in a 3D printer, almost all of which are driven by the rotation of stepper motors. While these gears are typically inaccessible, it’s much easier for the smaller fingers of children to get caught within these moving parts. It’s good practice for both kids and adults to refrain from touching the moving parts of a 3D printer while printing is ongoing. Heat Heat is an important part of 3D printing. It also provides some of its most pervasive hazards. Depending on the filament you’re working with, you might have an extruder temperature that goes as high as 200 to 250 °C. Most 3D printers also have heated print beds that can be heated close to 100 °C. The filament material, of course, is also very hot when it comes out of the extruder nozzle. These are things to watch out for, especially if you’re dealing with a bunch of curious children. Fumes When 3D printing, massive heat is applied to the plastic filament materials. Different filaments react in different ways to this heat, but it is much safer to assume that they all release fumes that can range from irritating to downright toxic. Even if you can’t smell anything, the pressure and heat of extrusion also release plastic micro-particles which can result in long-term respiratory problems in humans. Tools Aside from the 3D printer itself, completing or finishing 3D printing projects will often involve the use of other tools. Some of these tools are sharp and can still cause injury when used improperly or without proper supervision. If absolutely necessary, you may have to incorporate training for using these tools into your 3D printing class. However, there are tools that are simply too dangerous to leave in the hands of small children. In listing down these potential hazards, one must always recognize that children are naturally curious and that they might not have developed a sufficient level of motor skills to work with small parts or tools. This means that there must always be a context in the development of safety practices – a different set of rules will be needed between middle schoolers and very young students. Best 3D printing safety practices for kids The best safety measure is one that eliminates the hazard completely. If this cannot be done, the next best thing is to reduce the hazard or prevent access to it. These will be our guiding principles in formulating safety measures for kids for 3D printing education. Get a 3D printer with an enclosure The best way to keep the kids away from the moving or hot parts of a 3D printer is to simply isolate them. Fortunately, a lot of the new desktop-scale 3D printers being sold nowadays come with built-in enclosures. Models from Flashforge, Dremel, and Monoprice are some good options. These are ideal because they provide protection and isolate the fumes of 3D printing while still allowing students to watch while the 3D printing process unfolds. The physical barrier is highly effective in discouraging kids from poking and prodding the 3D printer while it is still running. You can also set these 3D printers to stop operations as soon as the enclosure or cover is removed, ensuring that no accidents happen even if you’re not actively supervising. Place warning stickers on parts that can get hot We realize that warning stickers don’t always work, especially with kids, but it’s still a good idea to have them, nonetheless. They are a good indicator of which parts of the 3D printer get hot. This is a lesson that most people get to learn the hard way, after all. For best results, we suggest sticking warning labels that are colored bright red. Make sure to use stickers that are actually meant for use in high temperatures, lest you end up with one that gets washed out after just a few weeks. Inspect the 3D printer before use A major responsibility of the instructor is to inspect the 3D printers before use to check for any signs of damage. If there are any exposed wires, then it might be a good idea to have the printer repaired first. Do not touch any parts of a 3D printer while it is running A good general rule of thumb is to tell your students that under no circumstance should they touch any of the parts of a 3D printer while it is still running except for the control panel. This rule applies to students of all ages as well as to you as the instructor – yes, this is a great opportunity to lead by example. Avoid crowding around the 3D printer while it is running Even with all safeguards in place, it is best to enforce a minimum distance between your students and the 3D printer while it is still running. Not only does this help prevent curious fingers from prodding the machine, but it also lessens their exposure to a 3D printer’s harmful fumes. Letting them watch the 3D printer from about five feet away should let them appreciate the process without exposing them to unnecessary hazards. Do not eat or drink near the 3D printer It’s a good idea to treat your 3D printing class like you would a chemistry laboratory – everyone should be wearing the proper protective equipment while working, and there should be no eating or drinking in class. Any food or drink has the potential of getting contaminated with the chemical fumes that 3D printing releases. A spilled drink will also be bad news for any electronics and can result in some extreme accidents. Have students wear goggles, gloves, and respiratory protection A 3D printing class is an excellent avenue to teach students about general safety. Part of safety is making sure that you are wearing safety equipment appropriate to the activity you are doing. In the case of 3D printing, you will want to wear protection for your eyes, mouth, and nose to avoid chemical inhalation or contamination. Heat-resistant gloves are also recommended whenever you need to touch potentially hot parts. Since chemical fumes could be anywhere in the classroom, we recommend having all the students wear eye and breathing protection whenever a 3D printer is running as long as they are in the same room. Make sure to use masks that have been specially designed for chemical fumes and not just common particulates. Print in a well-ventilated area If you have the option to open windows during printing, then do so. This will help disperse the fumes that 3D printers emit. This is a recommended measure even if you’re using a fully enclosed 3D printer with a dedicated filtered vent. If your room does not have large windows, then you might want to reconsider relocating your class to somewhere with better ventilation. Only print with PLA PLA is probably the friendliest filament to work with if you’re teaching 3D printing to kids. It prints at lower temperatures, does not need a heated printing bed, and does not release unpleasant fumes. PLA also isn’t as prone to warping as other 3D printing filaments, making it less likely for your students to go through the frustrating experience of having to start a 3D printing project all over. Watch out for signs of asthma, allergy, or any flu-like symptoms There’s a good chance that the kids in your class have not been exposed to the type of chemical fumes that 3D printers release. Even with breathing protection, you will need to keep a close eye on your students and watch out for adverse reactions. If any of your students show signs of difficulty breathing or allergic reactions, then it would be best to have them step outside the room right away. Get in touch with medical personnel if symptoms don’t improve after a few minutes. As with most safety guidelines, it’s equally important to be receptive to adding or revising the rules as you see fit. Different facilities may require a different set of rules depending on the goals of the course and the available equipment. Final thoughts It wasn’t that long ago when ‘shop class’ was a common thing in schools. Learning woodworking is no longer as common nowadays and have been replaced by more tech-oriented fields. With schools opening courses on 3D printing, we feel it our duty to try and provide assistance on how they can keep these classes safe. The good news is that a lot of desktop-scale 3Dprinters for sale today have been pretty well-designed when it comes to safety. If you can get an enclosed 3D printer with an integrated HEPA filter vent, then that’s already half the battle won. The post 3D Printing Safety Tips for Kids appeared first on 3D Insider.

    rabbit bones

    There are good animal CT scans on Duke University's repository. There are also a lot of stl models, tif's and all kind of media content you can possibly want. Just don't forget to quote them, this is an intellectual property... OR you can make a CT scan of a rabbit and segment it into a 3D model by yourself or you can hire one of us to do it. THEN the intellectual rights will be yours. If you want just to download a rabbit skeleton and to 3d print it, go for the Duke University. I am really excited by their Ape and Hominin collection - already 3d printed few of them. The dinosaurs are also really good.

    You don't need to create separate DICOM files for the skull and mandible. Depending on the overlap of the teeth, you can erase some of the segmentation in order to create gaps between the skull and mandible--if you are segmenting yourself. If you are uploading to democratiz3d, you can download the model and then either apply a plane cut in Meshmixer or if you want the actual articulations, you can "paint" the parts of the model to delete to create the necessary gaps, then repair the holes. Again, the difficulty would depend on whether you can separate the teeth on the maxilla from the mandible.

    Ender 3's bigger bro, Creality CR-10 is better in any possible way - huge building volume (300-300-400 mm), better controller, better extruder and hotend, double Z axis, safer power supply... I bought my CR-10S on Black Friday for 320$... I'm not printing on it often - my other printers are much better and more expensive. But for small operation, Ender 3 and CR-10 are quite good. There are 3d printing farms with those printers and they can be very reliable after some hardware upgrades and tunning.

    Stroke is a disease that affects the arteries leading to and within the brain. It is the number five cause of death and a leading cause of disability in the United States. In 2010, worldwide prevalence of stroke was 33 million, with 16.9 million people having a first stroke. Stroke is the leading cause of adult disability. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or ruptures. When that happens, part of the brain cannot get the blood and oxygen it needs, and brain cells die. This 3D printable model of stroke contains three STL files for bioprinting. One STL file is for printing the cerebral arteries. There is a skull STL file and another file for printing the filling inside the skull which provides support for placing the vasculature in the proper position within the model. The files have been zipped to reduce file size. You will need to unzip the files once you have downloaded them.These files are distributed under the Creative Commons license Attribution-NonCommercial-NoDerivs. Please respect the terms of the licensing agreement.

    - Is it typically a requirement to have latticed internal volumes to reduce material costs? In my experience, the model have to be solid and without internal meshes. The material cost can be controlled with the percentage and the type of the infill. - What about dowels/pins so that the model can be assembled? Do people usually want this? If you're printing a bone model in two parts, its better to glue them together after the print. If you're printing a model with a important cavity (skull or aorta), pins or sockets for neodymium magnets are a choice, which guarantees good alignment for the parts of the model and increases usability. The magnets are better, unless your client specifically prefer pins. - Are there any other considerations that would make these models more valuable to the community - I potentially have a few more anatomies that could be of value. Make them shinier, more stable and design a stand for the model.

    If you are planning on using the democratiz3D service to automatically convert a medical scan to a 3D printable STL model, or you just happen to be working with medical scans for another reason, it is important to know if you are working with a CT (Computed Tomography or CAT) or MRI (Magnetic Resonance Imaging) scan. In this tutorial I'll show you how to quickly and easily tell the difference between a CT and MRI. I am a board-certified radiologist, and spent years mastering the subtleties of radiology physics for my board examinations and clinical practice. My goal here is not to bore you with unnecessary detail, although I am capable of that, but rather to give you a quick, easy, and practical way to understand the difference between CT and MRI if you are a non-medical person. Interested in Medical 3D Printing? Here are some resources: Free downloads of hundreds of 3D printable medical models. Automatically generate your own 3D printable medical models from CT scans. Have a question? Post a question or comment in the medical imaging forum. A Brief Overview of How CT and MRI Works For both CT (left) and MRI (right) scans you will lie on a moving table and be put into a circular machine that looks like a big doughnut. The table will move your body into the doughnut hole. The scan will then be performed. You may or may not get IV contrast through an IV. The machines look very similar but the scan pictures are totally different! CT and CAT Scans are the Same A CT scan, from Computed Tomography, and a CAT scan from Computed Axial Tomography are the same thing. CT scans are based on x-rays. A CT scanner is basically a rotating x-ray machine that takes sequential x-ray pictures of your body as it spins around. A computer then takes the data from the individual images, combines that with the known angle and position of the image at the time of exposure, and re-creates a three-dimensional representation of the body. Because CT scans are based on x-rays, bones are white and air is black on a CT scan just as it is on an x-ray as shown in Figure 1 below. Modern CT scanners are very fast, and usually the scan is performed in less than five minutes. Figure 1: A standard chest x-ray. Note that bones are white and air is black. Miscle and fat are shades of gray. CT scans are based on x-ray so body structures have the same color as they don on an x-ray. How does MRI Work? MRI uses a totally different mechanism to generate an image. MRI images are made using hydrogen atoms in your body and magnets. Yes, super strong magnets. Hydrogen is present in water, fat, protein, and most of the "soft tissue" structures of the body. The doughnut of an MRI does not house a rotating x-ray machine as it does in a CT scanner. Rather, it houses a superconducting electromagnet, basically a super strong magnet. The hydrogen atoms in your body line up with the magnetic field. Don't worry, this is perfectly safe and you won't feel anything. A radio transmitter, yes just like an FM radio station transmitter, will send some radio waves into your body, which will knock some of the hydrogen atoms out of alignment. As the hydrogen nuclei return back to their baseline position they emit a signal that can be measured and used to generate an image. MRI Pulse Sequences Differ Among Manufacturers The frequency, intensity, and timing of the radio waves used to excite the hydrogen atoms, called a "pulse sequence," can be modified so that only certain hydrogen atoms are excited and emit a signal. For example, when using a Short Tau Inversion Recovery (STIR) pulse sequence hydrogen atoms attached to fat molecules are turned off. When using a Fluid Attenuation Inversion Recovery (FLAIR) pulse sequence, hydrogen atoms attached to water molecules are turned off. Because there are so many variables that can be tweaked there are literally hundreds if not thousands of ways that pulse sequences can be constructed, each generating a slightly different type of image. To further complicate the matter, medical scanner manufacturers develop their own custom flavors of pulse sequences and give them specific brand names. So a balanced gradient echo pulse sequence is called True FISP on a Siemens scanner, FIESTA on a GE scanner, Balanced FFE on Philips, BASG on Hitachi, and True SSFP on Toshiba machines. Here is a list of pulse sequence names from various MRI manufacturers. This Radiographics article gives more detail about MRI physics if you want to get into the nitty-gritty. Figure 2: Examples of MRI images from the same patient. From left to right, T1, T2, FLAIR, and T1 post-contrast images of the brain in a patient with a right frontal lobe brain tumor. Note that tissue types (fat, water, blood vessels) can appear differently depending on the pulse sequence and presence of IV contrast. How to Tell the Difference Between a CT Scan and an MRI Scan? A Step by Step Guide Step 1: Read the Radiologist's Report The easiest way to tell what kind of a scan you had is to read the radiologist's report. All reports began with a formal title that will say what kind of scan you had, what body part was imaged, and whether IV contrast was used, for example "MRI brain with and without IV contrast," or "CT abdomen and pelvis without contrast." Step 2: Remember Your Experience in the MRI or CT (CAT) Scanner Were you on the scanner table for less than 10 minutes? If so you probably had a CT scan as MRIs take much longer. Did you have to wear earmuffs to protect your hearing from loud banging during the scan? If so, that was an MRI as the shifting magnetic fields cause the internal components of the machine to make noise. Did you have to drink lots of nasty flavored liquid a few hours before the scan? If so, this is oral contrast and is almost always for a CT. How to tell the difference between CT and MRI by looking at the pictures If you don't have access to the radiology report and don't remember the experience in the scanner because the scan was A) not done on you, or you were to drunk/high/sedated to remember, then you may have to figure out what kind of scan you had by looking at the pictures. This can be complicated, but don't fear I'll show you how to figure it out in this section. First, you need to get a copy of your scan. You can usually get this from the radiology or imaging department at the hospital or clinic where you had the scan performed. Typically these come on a CD or DVD. The disc may already have a program that will allow you to view the scan. If it doesn't, you'll have to download a program capable of reading DICOM files, such as 3D Slicer. Open your scan according to the instructions of your specific program. You may notice that your scan is composed of several sets of images, called series. Each series contains a stack of images. For CT scans these are usually images in different planes (axial, coronal, and sagittal) or before and after administration of IV contrast. For MRI each series is usually a different pulse sequence, which may also be before or after IV contrast. Step 3: Does the medical imaging software program tell you what kind of scan you have? Most imaging software programs will tell you what kind of scan you have under a field called "modality." The picture below shows a screen capture from 3D Slicer. Looking at the Modality column makes it pretty obvious that this is a CT scan. Figure 3: A screen capture from the 3D Slicer program shows the kind of scan under the modality column. Step 4: Can you see the CAT scan or MRI table the patient is laying on? If you can see the table that the patient is laying on or a brace that their head or other body part is secured in, you probably have a CT scan. MRI tables and braces are designed of materials that don't give off a signal in the MRI machine, so they are invisible. CT scan tables absorb some of the x-ray photons used to make the picture, so they are visible on the scan. Figure 4: A CT scan (left) and MRI (right) that show the patient table visible on the CT but not the MRI. Step 5: Is fat or water white? MRI usually shows fat and water as white. In MRI scans the fat underneath the skin or reservoirs of water in the body can be either white or dark in appearance, depending on the pulse sequence. For CT however, fat and water are almost never white. Look for fat just underneath the skin in almost any part of the body. Structures that contained mostly water include the cerebrospinal fluid around the spinal cord in the spinal canal and around the brain, the vitreous humor inside the eyeballs, bile within the gallbladder and biliary tree of the liver, urine within the bladder and collecting systems of the kidneys, and in some abnormal states such as pleural fluid in the thorax and ascites in the abdomen. It should be noted that water-containing structures can be made to look white on CT scans by intentional mixing of contrast in the structures in highly specialized scans, such as in a CT urogram or CT myelogram. But in general if either fat or fluid in the body looks white, you are dealing with an MRI. Step 6: Is the bone black? CT never shows bones as black. If you can see bony structures on your scan and they are black or dark gray in coloration, you are dealing with an MRI. On CT scans the bone is always white because the calcium blocks (attenuates) the x-ray photons. The calcium does not emit a signal in MRI scans, and thus appears dark. Bone marrow can be made to also appear dark on certain MRI pulse sequences, such as STIR sequences. If your scan shows dark bones and bone marrow, you are dealing with an MRI. A question I am often asked is "If bones are white on CT scans, if I see white bones can I assume it is a CT?" Unfortunately not. The calcium in bones does not emit signal on MRI and thus appears black. However, many bones also contain bone marrow which has a great deal of fat. Certain MRI sequences like T1 and T2 depict fat as bright white, and thus bone marrow-containing bone will look white on the scans. An expert can look carefully at the bone and discriminate between the calcium containing cortical bone and fat containing medullary bone, but this is beyond what a layperson will notice without specialized training. Self Test: Examples of CT and MRI Scans Here are some examples for you to test your newfound knowledge. Example 1 Figure 5A: A mystery scan of the brain Look at the scan above. Can you see the table that the patient is laying on? No, so this is probably an MRI. Let's not be hasty in our judgment and find further evidence to confirm our suspicion. Is the cerebrospinal fluid surrounding the brain and in the ventricles of the brain white? No, on this scan the CSF appears black. Both CT scans and MRIs can have dark appearing CSF, so this doesn't help us. Is the skin and thin layer of subcutaneous fat on the scalp white? Yes it is. That means this is an MRI. Well, if this is an MRI than the bones of the skull, the calvarium, should be dark, right? Yes, and indeed the calvarium is as shown in Figure 5B. You can see the black egg shaped oval around the brain, which is the calcium containing skull. The only portion of the skull that is white is in the frontal area where fat containing bone marrow is present between two thin layers of calcium containing bony cortex. This is an MRI. Figure 5B: The mystery scan is a T1 spoiled gradient echo MRI image of the brain. Incidentally this person has a brain tumor involving the left frontal lobe. Example 2 Figure 6A: Another mystery scan of the brain Look at the scan above. Let's go through our process to determine if this is a CT or MRI. First of all, can you see the table the patient is lying on or brace? Yes you can, there is a U-shaped brace keeping the head in position for the scan. We can conclude that this is a CT scan. Let's investigate further to confirm our conclusion. Is fat or water white? If either is white, then this is an MRI. In this scan we can see both fat underneath the skin of the cheeks which appears dark gray to black. Additionally, the material in the eyeball is a dark gray, immediately behind the relatively white appearing lenses of the eye. Finally, the cerebrospinal fluid surrounding the brainstem appears gray. This is not clearly an MRI, which further confirms our suspicion that it is a CT. If indeed this is a CT, then the bones of the skull should be white, and indeed they are. You can see the bright white shaped skull surrounding the brain. You can even see part of the cheekbones, the zygomatic arch, extending forward just outside the eyes. This is a CT scan. Figure 6B: The mystery scan is a CT brain without IV contrast. Example 3 Figure 7A: A mystery scan of the abdomen In this example we see an image through the upper abdomen depicting multiple intra-abdominal organs. Let's use our methodology to try and figure out what kind of scan this is. First of all, can you see the table that the patient is laying on? Yes you can. That means we are dealing with the CT. Let's go ahead and look for some additional evidence to confirm our suspicion. Do the bones appear white? Yes they do. You can see the white colored thoracic vertebrae in the center of the image, and multiple ribs are present, also white. If this is indeed a CT scan than any water-containing structures should not be white, and indeed they are not. In this image there are three water-containing structures. The spinal canal contains cerebrospinal fluid (CSF). The pickle shaped gallbladder can be seen just underneath the liver. Also, this patient has a large (and benign) left kidney cyst. All of these structures appear a dark gray. Also, the fat underneath the skin is a dark gray color. This is not in MRI. It is a CT. Figure 7B: The mystery scan is a CT of the abdomen with IV contrast Example 4 Figure 8A: A mystery scan of the left thigh Identifying this scan is challenging. Let's first look for the presence of the table. We don't see one but the image may have been trimmed to exclude it, or the image area may just not be big enough to see the table. We can't be sure a table is in present but just outside the image. Is the fat under the skin or any fluid-filled structures white? If so, this would indicate it is an MRI. The large white colored structure in the middle of the picture is a tumor. The fat underneath the skin is not white, it is dark gray in color. Also, the picture is through the mid thigh and there are no normal water containing structures in this area, so we can't use this to help us. Well, if this is a CT scan than the bone should be white. Is it? The answer is no. We can see a dark donut-shaped structure just to the right of the large white tumor. This is the femur bone, the major bone of the thigh and it is black. This cannot be a CT. It must be an MRI. This example is tricky because a fat suppression pulse sequence was used to turn the normally white colored fat a dark gray. Additionally no normal water containing structures are present on this image. The large tumor in the mid thigh is lighting up like a lightbulb and can be confusing and distracting. But, the presence of black colored bone is a dead giveaway. Figure 8B: The mystery scan is a contrast-enhanced T2 fat-suppressed MRI Conclusion: Now You Can Determine is a Scan is CT or MRI This tutorial outlines a simple process that anybody can use to identify whether a scan is a CT or MRI. The democratiz3D service on this website can be used to convert any CT scan into a 3D printable bone model. Soon, a feature will be added that will allow you to convert a brain MRI into a 3D printable model. Additional features will be forthcoming. The service is free and easy to use, but you do need to tell it what kind of scan your uploading. Hopefully this tutorial will help you identify your scan.

    Not a word about Prusa Slicer - maybe THE BEST slicer so far, frequently updated and user-friendly. Maybe Simplify3d has more useful options and extras, but it's not updated regularly, so in my opinion, it's number 2 after Prusa Slicer. The best slicer is Netfabb - an Autodesk program, which combines design, simulation and CAM in one and can do amazing stuff with basically everything (I'm talking about alchemy level stuff). The price is too hefty for my operation, though. Did you know, that you can use the latest version Fusion360 as a slicer? I was also surprised. It's actually not bad at all, but I prefer Prusa Slicer and Cura for my printers.

    Medical 3D printing isn't at a point where a user can buy a printer, plug it in and do a few prints a year. There is a big learning curve a user must go through in order for prints to turn out correctly. This is especially true for medical trial exhibits where certain anatomy or conditions need to be highlighted from a CT scan. This requires 3D printing expertise and medical training. Furthermore, you will need space and all the related tools that go with 3D printing. Some printer manufacturers show their printers sitting on an office desk. This really isn't practical because of the noise, heat and messy post print processing. We offer a 3D printing service specifically for medical trial exhibits: https://www.embodi3d.com/3d-printing-anatomy-models-for-medical-malpractice-trial-exhibits/

    This model is the right foot and ankle bone rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient unfortunately died 9.5 months after diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. The ankle is a hinge (or ginglymus) joint made of the distal tibia (tibial plafond, medial and posterior malleoli) superiorly and medially, the distal fibula (lateral malleolus) laterally and the talus inferiorly. Together, these structures form the ankle “mortise”, which refers to the bony arch. Stability is provided by the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL) laterally, and the superficial and deep deltoid ligaments medially. The ankle is one of my most common sites of musculoskeletal injury, including ankle fractures and ankle sprains, due to the ability of the joint to invert and evert. The most common ligament involved in the ATFL. Radiographic analysis of an ankle after injury should include the so-called “mortise view”, upon which measurements can be made to determine congruity of the ankle joint. Normal measurements include >1 mm tibiofibular overlap, </= 4mm medial clear space, and <6 mm of tibiofibular clear space. The talocrural ankle is measured by the bisection of a line through the tibial anatomical axis and another line through the tips of the malleoli. Shortening of the lateral malleolus can lead to an increased talocrural angle. The foot is commonly divided into three segments: hindfoot, midfoot, and forefoot. These sections are divided by the transverse tarsal joint (between the talus and calcaneus proximally and navicular and cuboid distally), and the tarsometatarsal joint (between the cuboids and cuneiforms proximally and the metatarsals distally). The first tarsometatarsal joint (medially) is termed the “Lisfranc” joint, and is the site of the Lisfranc injury seen primarily in athletic injuries. This model was created from the file STS_023.

    Methods 3D Medical imaging data was obtained in the .stl format. The hyoid bone was localized from the .stl --sectioned off in the software -- and that part of the anatomy was revised using 3D modeling techniques to be highly adaptable to 3D printing platforms for potential regenerative medicine applications. Author and Licensing This hyoid bone re-topology was performed by Chris Leggett.
