Dear Community Members,
After many months of work, we are happy to announce the addition of a feature that will allow you to sell medical models you have designed on Embodi3D.com. While we always have encouraged our members to consider allowing their medical STL files to be downloaded for free, we understand that when a ton of time is invested in creating a valuable and high-quality model, it is reasonable to ask for something in return. Now Embodi3D members have two options: 1) You can share
In this tutorial we will learn how to use the free medical imaging conversion service on embodi3D.com to create detailed anatomic muscle and skin 3D printable models in STL file format from medical CT scans. Muscle models show the detailed musculature by subtracting away the skin and fat. Even when created from a scan of an obese person, the model looks like it comes from a bodybuilder, Figure 1A. Skin models show an exact replica of the skin surface. The finest details are captured, including w
Please note the democratiz3D service was previously named "Imag3D"

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
Infants born with congenital heart defects often need to undergo surgery quickly to repair the holes in their heart. But for a two week old at a hospital in New York, the surgery was going to be especially difficult. The child’s heart not only had holes that needed to be repaired, but the heart was structured in a very unusual way. Dr. Emile Bacha related the heart chambers to that of a maze. Typically in cases like this, doctors would have to open the chest and stop the heart in order to figure
A two week old baby, with a complicated heart problem that required an equally complicated surgery, in a New York hospital has been saved with the help of a 3D printed heart.
At the Morgan Stanley Children’s Hospital in New York City, the baby’s heart was 3D printed with the help of an MRI scan data. The baby was suffering from coronary heart disease (CHD). Commonly with CHD, the heart is riddled with holes—this is likewise true of the baby’s heart but what made the condition worse was that the
Gone is the time when would-be surgeons have to study human anatomy with the help of a detailed picture of a human heart or with the help of a cadaver heart. This time around, thanks to the invention of 3D printers, trainee surgeons can study a lifelike heart prosthetic—with all the works. This is as close as you can get to a real human heart without a patient, of course.
The creator of this 3D printed prosthetic is Richard Arm of the Nottingham Trent University. The prosthetic is made from a s
Today when a child is born without ears or with severe ear deformities they may have to undergo four or more surgeries to correct the problem. This not only means months waiting for the process to be completed, but painful recoveries and significant expense. However, researchers at the University College London are about to begin a trial in which they use a 3d printer to create new ears.
Early next year researchers will start a clinical trial on children in London and Mumbai to create new ears
Garrett Peterson is an 18-month old baby who has never been to his home because of a medical condition known as Tetralogy of Fallot with a missing pulmonary valve. This condition places a great deal of pressure on the baby’s airways. And worse is, the condition led to the development of tracheobronchomalacia which is the softening of the bronchi and trachea thereby causing his airways to become tiny slits. With this condition, baby Garrett has lived all his life attached to a ventilator in a hos
A 3D printer, which is already in the process of being commercialized, makes 3D printed skin grafts a reality. Known as the PrintAlive Bioprinter, it was designed and created by engineers of the University of Toronto, namely Arianna McAllister, Boyang Zhang, Lian Leng and associate professors Milica Radisic and Axel Guenther. The designed printer has already reaped the 2014 James Dyson Award for student design.
What’s so groundbreaking about this microwaved sized 3D printer is that it can creat
Organovo Holdings, Inc. is a manufacturer and creator of functional 3-Dimensional human tissues that are applied in therapeutic applications and medical research. Organovo collaborates with academic and pharmaceutical partners in order to come up with 3D human biological disease models.
With the current innovation of the 3D bioprinted liver tissue, it opens a lot of possibilities and new hopes when it comes to drug discovery. Discovering drugs is an easy process but testing the drugs for safety
Lately I've been working on creating a 3D printed human heart from a CT scan. Printing cardiovascular structures like the heart is more difficult than bony structures since the blood vessels are usually not well visualized without a CT scan that uses intravenous contrast. Furthermore, the heart is always moving, and special techniques need to be performed during the scan to generate high-quality images that are free from motion artifact.
This is one of several models I've been working on. I
Researchers at the University of Illinois at Urbana-Champaign have created an innovative robot which has a more dramatic range of motion and a more accurate control of its movements. Researchers hope that this "bio-bot" can enhance future designs of robots for research, construction, exploration, and even disaster relief operations.
This bio bot is powered by a skeletal muscle tissue from a mouse. It is skeletal tissues that drive human movement – from a little twitch of the finger to the whole
With the combined efforts of the Bristol Robotics Laboratory and the researchers from the University of Bath (Department of Chemical Engineering), they have created a water sensor through 3D printing that can check the water system’s safety levels for consumption. The device created by the researchers can provide round the clock water quality assessment which is a useful tool for people in the developing world to ensure that their drinking water is safe.
With the help of a 3d printer, the resea
One of the biggest obstacles that the medical world confronts when it comes to 3D Bio-printing is the cost of the printers which can go for US$300,000 or more. But a recent development by the Louisiana Tech University researchers showed that it was possible to create drug emitting implants with a MakerBot Replicator which is an affordable desktop 3D printer. This has opened a lot of avenues for the medical world to create innovative ways of prototyping possibilities to treat diseases and patient
Community member Mike Kessler has successfully printed a half skull available for download in the File Vault using a filament printer. He made the skull to help a family member who is learning skull anatomy in medical school. The skull looks great. Fantastic job Mike! Check out Mike's complete album here.
If you have had success with printing one of the 3D anatomic models available for download on the site, please let us know how things went. If you are creating your own medical 3D models,
I've been working on ways to artistically expand on 3D printed anatomic models beyond an exact replica of the anatomy. My first project is this Lace Skull. The skull is based on an anatomically accurate skull generated from a CT scan. I have made several of the earlier skull models available for download on the Embodi3D website here and here. Using a variety of methods, I have transformed the skull and given it a unique lace-like appearance. The overall surface contours are still anatomically ac
Today I was interviewed and featured on Radbuz. I spoke with Dr. Jenny Chen about my experiences with 3D printing in the biomedical space and where I think the field is going.

E-Nabling the Future is a volunteer organization dedicated to creating inexpensive 3D printable prosthetic hands and arms for children around the globe who are missing limbs. The movement has grown from an informal collaboration to a veritable movement, and they are now producing functional and inexpensive prosthetic limbs. Traditionally designed arm and hand prostheses can cost up to $40,000. According to 3Dprint.com, it is now possible to create an entire functional my electric arm for $350. T
There has been a lot of hype recently about 3D printed organs. There have been several instances in recent memory where somebody holds up a kidney or liver shaped 3D printed blob of jello-like cells and the press goes wild, as if the jello blob, because it is shaped like an organ, must be an organ and is ready to go directly into a patient. As someone who works with transplant patients all the time I can tell you it's not that simple. Real organs are incredibly complex.
Take the liver for e
Thanks to 3D printing understanding of the complex neural pathways of the human brain became a little bit easier. The Philadelphia-based Franklin Institute's new exhibit, Your Brain, features a striking 3D printed model of the white matter tracts of the human brain. White matter tracts are the pathways that nerve cells use to connect to each other inside the brain, and are incredibly complex.
Dr. Jayatri Das, chief bioscientist at The Franklin Institute, incorporated the displays in
Last week, 3D Systems announced the successful completion of its pilot program for a 3D-printed brace for children and young adults with scoliosis (curved spine). As with other 3D-printed braces, the “Bespoke Brace” is personalized for each patient. In a first step, the patient is fitted with a prototype brace. Once this prototype has been customized, it is digitized to create a digital reference underlay. Next, the brace is further adjusted digitally and finally 3D-printed using selective laser
We have seen some interesting articles and posts on the amazing things 3D-printing can do for rare medical conditions. But have you, like me, been wondering how this promising technology can benefit you, personally? How it can benefit lots of people, rather than just a few with serious medical conditions? Here is an example: you can have an ankle brace 3D-printed that fits your ankle perfectly! Significantly reduce the risk of a sprained ankle when running, playing soccer, volleyball, basketball
I apologize for being slow with the posting recently. I was at a conference last week and this week I have been working on creating a 3D printable cardiac and arterial model (see image). More interesting blog articles will be coming shortly.
In the meantime, I encourage you to check out the blog of my friend, neuroradiologist, and 3D printing enthusiast Jenny Chen, MD., at Radbuz.com. You can follow her on twitter at @radbuzzz.
This is the second in a series of articles about skull models created from CT scan data and designed to provide a low-cost means of anatomy teaching. To see my past article about the skull base model, click here.
Learning detailed anatomy is a grueling process that doctors, nurses, and other health science students must go through. Traditionally, learning anatomy involved detailed study of textbooks, but learning 3D structures from 2D pages just doesn't work well. Dissecting cadavers is the
Researchers at the Children's National Medical Center in Washington DC have used 3D printed heart models to aid repair of congenital heart defects. In the International Journal of Cardiology, the researchers report the case of a patient with transposition of the great arteries, a congenital heart defect in which the pulmonary artery and aorta are switched. Without treatment this condition is fatal in infancy. The man apparently had surgical treatment as a child, but as an adult began to have pro
The base of the skull is one of the most complex and difficult parts of the body for doctors in training to master. And one of the most important. It is comprised of multiple bones (the ethmoid, sphenoid, occipital, frontal, parietal, and temporal, to be exact) and has numerous foramina (holes) through which arteries, veins, and the vital cranial nerves and spinal cord exit the skull on their way to and from the body.
These structures, although very small, are critically important c
