  1. A member recently messaged me with a question about a brain she printed from this file. I as posting the response here in the hope that it will help others in the community. QUESTION "I came across your 3D printable human brain model and was able to successfully print it. Thank you for sharing it! Now I need to post-process it and am wondering if you can explain how you post-processed your print? I have never done the post-processing before and am not sure the best approach to take. I have attached a picture of our printed brain for your reference. Thank you in advance for insight you can offer!" RESPONSE: Based on the picture you attached, it looks like you used a single extruder printer and printed both the supports and model in the same material, presumably PLA. You need to tear off the supports using pliers. This can be a time-consuming job as getting in every nook and cranny can be difficult. If you find the supports are stuck to much to the model, you may have to adjust some of the settings in your slicer software to compensate. There may be a rough surface where the supports touch the model that you can sand off. If you have a dual extrusion printer, you can print the supports using a water soluble material such as PVA, which makes the supports easy to remove by soaking in water. Dual extruders can be finicky and you will likely have to spend a lot of time trying out different settings to get the supports to work just right, including calibrating the XY offset of the second extruder, determining optimal print temperature for the PLA and support to work together, overhang speed, support infill percentage, etc. This process is very time consuming but gratifying once you get your printer dialed in. If you don't want to deal with the headache, embodi3D has a 3D printing service and can print and ship to you. Hope this helps. Dr. Mike

    An aneurysm of the abdominal aorta in close proximity to horseshoe kidney. Presurgical model. The operation is ongoing. Honestly, I'm pretty happy with the result (and also the surgical team, which ordered the model). I printed it on Prusa MK3S, the kidney with the veins and the distal parts of the arteries with white Esun PLA, the aorta with red 3dJake Eco PLA, on 0,150mm layer height. The kidney is printed on 30% gyroid infill and 2 perimeters, with support on build plate only plus several support enforcers. The aorta is with 4 perimeters and 100% concentric infill, with support on build plate only and few support blockers. I glued them together with cyanacrylic glue and used a touch of red acrylic paint to make the glued parts more appealing. It took 300 grams of plastic and the printing time was 36 hours because of the kidney.

    This is my best selling model for 2019. Download, print, assemble, enjoy. Merry Christmas Originally modded as an engagement ring box, it became really popular birthday gift for the colleague from heart-related departments. I'm selling one of those models for 35$ I'm always bringing few, when I'm going on conference. Really nice gift. I'm printing those with Silk PLA. The metalic colors looks fantastic. I'm using several support blockers for the atrii, because this negates the artefacts and makes the whole upper part hollow. It requires some experience... Slice thickness: 0,15mm Infill: 30% gyroid Circular bottom fill pattern. Six neodymium magnets, 8x2mm. If you use too powerful magnets, the parts are closing so strong, that they can hurt someone. N50 are fine. cyanacrilic glue. Make sure you're gluing the magnets with the right poles!

This model contains a high grade stenosis in the proximal left common iliac vein, the classic position of the so-called May-Thurner stenosis. In May-Thurner syndrome, chronic compression and scarring of the proximal left common iliac vein, is caused by the crossing right common iliac artery. This results in stenosis of the left common iliac vein, slow blood flow, and eventually clotting and formation of deep vein thrombosis (DVT). After the DVT is cleared with anticoagulation or thrombectomy/thrombolysis, the iliac vein stenosis must be treated with venous stenting. Contact us for model information and prices This model has a 4 mm thick, 9 mm wide stenosis at the crossing point between the left common iliac vein and the right common iliac artery. It is perfect for practicing venous stenting and thrombectomy/ thrombolysis.

    This is a .stl file produced from a CT scan of myself. I used 'InVesalius 3.0 free' to convert the 2D dicom images into the .stl file. I use either 3D Tool or Materialise's MiniMagics (free versions) to view and manipulate the 3D image. I have been told I had a severe hyperflexion injury to my c spine during an assault in 1988 and sustained a number of fractures and subluxations which were not diagnosed by a hospital as they discharged me from the ER in error before I had been examined by a Dr. It wasn't until I had a CT scan in 2011 and produced 3D images from it that I discovered various bony abnormalities that were subsequently identified as fractures & subluxations by experts. I understand the right transverse process of T1, tip of C6 spinous process and the left greater cornu of the hyoid bone are the most obvious old fractures that can be seen. cervical, spine, .stl, 3d, printing, .stl, bone, 3d, model, printable, vertebrae, spine, atlas, axis, body, intervertebral, space, laminae, facet, transverse, process, spinous, process, printable, 3d, model, ribs, clavicle,

  15. Bones The main advantage of the orthopedical presurgical 3d printed models is the possibility to create an accurate model, which can be used for metal osteosynthesis premodelling - the surgeons can prepare (bend, twist, accommodate) the implants prior the operation. After a sterilisation (autoclaving, UV-light, gamma-ray etc etc), those implants can be used in the planned surgery, which will decrease the overall surgery time (in some cases with more than an hour) with all it's advantages, including a dramatic decreasing of the complication rates, the X-ray exposure for the patient and for the surgeons, the cost and the recovery rates etc etc. For this purpose, you need a smooth bone model, with clearly recognizable and realistic landmarks, realistic measurements and physical properties, close to the real bone. Traditionally, the orthopedical surgeons in my institution used polystyrene models, made by hand, now they have access to 3d printed models and they are better in any way. Here are some tips how to print that thing. 1. Method - FDM. The bone models are the easiest and the most forgiving to print. You can make them with literally every printer you can find. FDM is a strong option here and, in my opinion, the best method on choice.2. Matherial - PLA - it's cheap, it's easy to print, it's the bread and butter for the bone printing. Cool extruding temperature (195-200C) decrease the stringing and increases the details in the models.3. Layer heigh - 0,150mm. This is the best compromise between the print time, the quality and the usability of the models.3. Perimeters (shell thickness) - 4 perimeters. One perimeter means one string of 3d printed material. It's width depends on the nozzle diameter and the layer thickness. For Prusa MK3 with 0,4mm nozzle 1 perimeter is ~0,4mm. To achieve a realistic cortical bone, use 4 perimeters (1,7mm). The surgeons loves to cut stuff, including the models, in some cases I have to print several models for training purposes. 4 perimeters PLA feels like a real bone.4. Infill - 15% 3d infill (gyroid, cuboid or 3d honey comb). The gyroid is the best - it looks and feels like a spongy bone. It's important to provide a realistic tactile sensation for the surgeons, especially the trainees. They have to be able to feel the moment, when they pass the cortical bone and rush into the spongiosa.5. Color - different colors for every fracture fragment. If the model is combined with a 3D visualization, which colors corresponds with the colors of the 3d print, this will make the premodelling work much easier for the surgeons. Also, it looks professional and appealing. 6. Postprocessing - a little sanding and a touch of a acrylic varnish will make the model much better.7. Support material - every slicer software can generate support, based on the angle between the building platform and the Z axis of the model. You can control this in details with support blockers and support enforcers, which for the bones is not necessary, but it's crucial for the vessels and the heart.Conclusions - the bone models are easy to make, they look marvelous and can really change the outcome of every orthopedical surgery.
  16. The Coalition for Imaging and Bioengineering Research (CIBR) is a dedicated partnership of academic radiology departments, patient advocacy groups, and industry with the mission of enhancing patient care through advances in Biomedical Imaging. My good friend and colleague Dr. Beth Ripley and I recently participated in the sixth annual Medical Technology Showcase at Capitol Hill organized by CIBR, representing the Department of Radiology at the Brigham and Women’s Hospital (BWH) where we emphasized the importance of 3D printing in healthcare. The annual Medical Technology showcase aims to bring examples of medical breakthroughs in imaging and bioengineering to members of congress and demonstrate how these advances are impacting patient care. In addition to educating policy makers and the public about innovative imaging technology, the event demonstrates the value of NIH funded academic research and the importance of collaborations between academia, industry and patient advocacy groups. Our display booth comprised of the Department of Radiology at BWH, the Lung Cancer Alliance, and Fujifilm was a hit among attendees and we were pleased to see the level of interest in medical 3D printing. We displayed 3D printed models that have been used for different clinical applications and our booth partners from Fujifilm demonstrated Synapse 3D, a software that allows conversion of 2D image data from CT/MRI into 3D printable files. Our goal was to demonstrate the importance of 3D printing in pre-surgical planning and how it can benefit patients by allowing surgeons to devise a patient specific treatment strategy and minimize post-surgical complications. Sheila Ross, a lung cancer survivor and patient advocate from the Lung Cancer Alliance emphasized how 3D printed models can give patients and their families a better understanding of the planned procedure. A lung model from Fujifilm demonstrating a nodule (green) and surrounding bronchioles The Lung & Brain cookies might have been slightly more popular than our 3D models It is our hope that more funding and resources will be allocated to investigate innovative medical technologies such as 3D printing, which can then be translated to impact patient care. In order to transform 3D printing from being a fad, to a mainstream tool that fosters precision medicine, evidence based benefits of its different applications will need to be demonstrated in clinical trials which will require funding.

  20. I'm trying to 3d print my own skull just for fun and well I have the DCOM file but every time when I try and convert it the whole skull doesn't come out. Whenever I convert the DCOM file any of them it only gives me from the top do about the middle of the eye socket and i want the whole thing. Can someone please help me and tell me what i might be doing wrong.
  21. I receive a lot of inquiries to my account. I'm going to try to share them with the community in the hope that any information that is shared can help many others. A member recently contacted me and asked the following: "I am a Biomaterials and Tissue Engineer by profession and recently got into 3d printing of medical implants. I would be greatly obliged if you could please advice me on designing 'cranial mesh' My task is to design titanium based cranial mesh. I would like to know if you can suggest me any tutorial on the same." Another member asks, " I am a resident in neurosurgery in Brazil and I have a dream to allow cheap cranioplasty for those in need that depend on Brazilian public health system. If you have some sort of tutorial using free software to make those prosthetic cranial grafts of a cheap way to make a mold out of it I will be glad to hear from you. I am planning on buying the ultimaker 2 printer which allows direct PEEK print and also PLA print for mold to go through autoclave." I must admit that I have limited experience with craniofacial implants. I know that the physicians at Walter Reed Army Medical Center in Bethesda Maryland are doing pioneering work in the field. Regarding making titanium-based implants I am unaware of any tutorials, but a search on Pubmed has yielded a few helpful articles. Here is one https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4073471/ From what I have seen most of these implants are designed using the Mimics system by Materialise. Regarding the low-cost solution for cranial implants, I'm not familiar with any freeware software that specifically does implants. From the hardware perspective, you may want to consider a Form 2 stereolithographic printer in addition to the Ultimaker 2 (FYI, there is a new Ultimaker 3 printer out). Formlabs, the makers of the Form 2 have a tutorial on using their printer to make molds for casting. https://formlabs.com/blog/3d-printing-for-injection-molding/ Formlabs has a dental biocompatible resin that I know some hospitals (Mayo Clinic) are using for in-surgery cutting guides. I heard them talk about that at a conference I recently attended. Whatever you do, make sure you follow the health safety rules in your country and take all necessary steps for patient safety.
  22. Please note the democratiz3D service was previously named "Imag3D" In this tutorial you will learn how to quickly and easily make 3D printable bone models from medical CT scans using the free online service democratiz3D®. The method described here requires no prior knowledge of medical imaging or 3D printing software. Creation of your first model can be completed in as little as 10 minutes. You can download the files used in this tutorial by clicking on this link. You must have a free Embodi3D member account to do so. If you don't have an account, registration is free and takes a minute. It is worth the time to register so you can follow along with the tutorial and use the democratiz3D service. >> DOWNLOAD TUTORIAL FILES AND FOLLOW ALONG << Both video and written tutorials are included in this page. Before we start you'll need to have a copy of a CT scan. If you are interested in 3D printing your own CT scan, you can go to the radiology department of the hospital or clinic that did the scan and ask for the scan to be put on a CD or DVD for you. Figures 1 and 2 show the radiology department at my hospital, called Image Management, and the CDs that they give out. Most radiology departments will have you sign a written release and give you a CD or DVD for free or with a small processing fee. If you are a doctor or other healthcare provider and want to 3D print a model for a patient, the radiology department can also help you. There are multiple online repositories of anonymized CT scans for research that are also available. Figure 1: The radiology department window at my hospital. Figure 2: An example of what a DVD containing a CT scan looks like. This looks like a standard CD or DVD. Step 1: Register for an Embodi3D account If you haven't already done so, you'll need to register for an embodi3d account. Registration is free and only takes a minute. Once you are registered you'll receive a confirmatory email that verifies you are the owner of the registered email account. Click the link in the email to activate your account. The democratiz3D service will use this email account to send you notifications when your files are ready for download. Step 2: Create an NRRD file with Slicer If you haven't already done so, go to slicer.org and download Slicer for your operating system. Slicer is a free software program for medical imaging research. It also has the ability to save medical imaging scans in a variety of formats, which is what we will use it for in this tutorial. Next, launch Slicer. Insert your CD or DVD containing the CT scan into your computer and open the CD with File Explorer or equivalent file browsing application for your operating system. You should find a folder that contains numerous DICOM files in it, as shown in Figure 3. Drag-and-drop the entire DICOM folder onto the Slicer welcome page, as shown in Figure 4. Click OK when asked to load the study into the DICOM database. Click Copy when asked if you want to copy the images into the local database directory. Figure 3: A typical DICOM data set contains numerous individual DICOM files. Figure 4: Dragging and dropping the DICOM folder onto the Slicer application. This will load the CT scan. Once Slicer has finished loading the study, click the save icon in the upper left-hand corner as shown in Figure 5. One of the files in the list will be of type NRRD. make sure that this file is checked and all other files are unchecked. click on the directory button for the NRRD file and select an appropriate directory to save the file. then click Save, as shown in Figure 6. Figure 5: The Save button Figure 6: The Save File box The NRRD file is much better for uploading then DICOM. Instead of having multiple files in a DICOM data set, the NRRD file encapsulates the entire study in a single file. Also, identifiable patient information is removed from the NRRD file. The file is thus anonymized. This is important when sending information over the Internet because we do not want identifiable patient information transmitted. Step 3: Upload the NRRD file to Embodi3D Now go to www.embodi3d.com, click on the democratiz3D navigation menu and select Launch App, as shown in Figure 7. Drag and drop your NRRD file where indicated. While NRRD file is uploading, fill in the "File Name" and "About This File" fields, as shown in Figure 8. Figure 7: Launching the democratiz3D application Figure 8: Uploading the NRRD file and entering basic information To complete basic information about your NRRD file. Do you want it to be private or do you want to share it with the community? Click on the Private File button if the former. If you are planning on sharing it, do you want it to be a free or a paid (licensed) file? Click the appropriate setting. Also select the License Type. If you are keeping the file private, these settings don't matter as the file will remain private. Make sure you accepted the Terms of Use, as shown in Figure 9. Figure 9: Basic information fields about your uploaded NRRD file Next, turn on democratiz3D Processing by selecting the slider under democratiz3D Processing. Make sure the operation CT NRRD to Bone STL is selected. Leave the default threshold of 150 in place. Choose an appropriate quality. Low quality produces small files quickly but the output resolution is low. Medium quality is good for most applications and produces a relatively good file that is not too large. High quality takes the longest to process and produces large output files. Bear in mind that if you upload a low quality NRRD file don't expect the high quality setting to produce a stellar bone model. Medium quality is good enough for most applications. If you wish, you have the option to specify whether you want your output file to be Private or Shared. If you're not sure, click Private. You can always change the visibility of the file later. If you're happy with your settings, click Save & Submit Files. This is shown in Figure 10. Figure 10: Entering the democratiz3D Processing parameters. Step 4: Review Your Completed Bone Model After about 10 to 20 minutes you should receive an email informing you that your file is ready for download. The actual processing time may vary depending on the size and complexity of the file and the load on the processing servers. Click on the link within the email. If you are already on the embodied site, you can access your file by going to your profile. Click your account in the upper right-hand corner and select Profile, as shown in Figure 11. Figure 11: Finding your profile. Your processed file will have the same name as the uploaded NRRD file, except it will end in "– processed". Renders of your new 3D model will be automatically generated within about 6 to 10 minutes. From your new model page you can click "Download this file" to download.

  25. Hello the Biomedical 3D Printing community, it's Devarsh Vyas here writing after a really long time! This time i'd like to share my personal experience and challenges faced with respect to medical 3D Printing from the MRI data. This can be a knowledge sharing and a debatable topic and I am looking forward to hear and know what other experts here think of this as well with utmost respect. In the Just recently concluded RSNA conference at Chicago had a wave of technology advancements like AI and 3D Printing in radiology. Apart from that the shift of radiologists using more and more MR studies for investigations and the advancements with the MRI technology have forced radiologists and radiology centers (Private or Hospitals) to rely heavily on MRI studies. We are seeing medical 3D Printing becoming mainstream and gaining traction and excitement in the entire medical fraternity, for designers who use the dicom to 3D softwares, whether opensource or FDA approved software know that designing from CT is fairly automated because of the segmentation based on the CT hounsifield units however seldom we see the community discuss designing from MRI, Automation of segmentation from MRI data, Protocols for MRI scan for 3D Printing, Segmentation of soft tissues or organs from MRI data or working on an MRI scan for accurate 3D modeling. Currently designing from MRI is feasible, but implementation is challenging and time consuming. We should also note reading a MRI scan is a lot different than reading a CT scan, MRI requires high level of anatomical knowledge and expertise to be able to read, differentiate and understand the ROI to be 3D Printed. MRI shows a lot more detailed data which maybe unwanted in the model that we design. Although few MRI studies like the contrast MRI of the brain, Heart and MRI angiograms can be automatically segmented but scans like MRI of the spine or MRI of the liver, Kidney or MRI of knee for example would involve a lot of efforts, expertise and manual work to be done in order to reconstruct and 3D Print it just like how the surgeon would want it. Another challenge MRI 3D printing faces is the scan protocols, In CT the demand of high quality thin slices are met quite easily but in MRI if we go for protocols for T1 & T2 weighted isotropic data with equal matrix size and less than 1mm cuts, it would increase the scan time drastically which the patient has to bear in the gantry and the efficiency of the radiology department or center is affected. There is a lot of excitement to create 3D printed anatomical models from the ultrasound data as well and a lot of research is already being carried out in that direction, What i strongly believe is the community also need advancements in terms of MRI segmentation for 3D printing. MRI, in particular, holds great potential for 3D printing, given its excellent tissue characterization and lack of ionizing radiation but model accuracy, manual efforts in segmentation, scan protocols and expertise in reading and understanding the data for engineers have come up as a challenge the biomedical 3D printing community needs to address. These are all my personal views and experiences I've had with 3D Printing from MRI data. I'm open to and welcome any tips, discussions and knowledge sharing from all the other members, experts or enthusiasts who read this. Thank you very much!
