Amazing 3D Printed Models on Display at RSNA 2014

Dr. Mike



3D printing is a hot topic at this year's Radiological Society of North America (RSNA) meeting in Chicago. I've been involved in medical 3D printing for the past two years, and every month there seems to be more interest. At this year's RSNA meeting, the level of interest is higher than I have ever seen before. There are literally dozens of sessions related to 3D printing in radiology, and they all seem to be very well attended. The Sunday session on "Fundamentals of 3D Printing" had a line out the door and down the hall as shown by the picture below. So many people were standing in the room that they had to close the session due to fire safety limits.


Perhaps one of the biggest draws is the vast array of striking 3D printed models on display from a variety of vendors that offer 3D printing and consulting services. 3D printer manufacturers have been working hard on new and exciting 3D printing materials. As a result, there is now a large selection of materials to choose from, each with a unique set of properties. When the right anatomy, materials, and printers are combined effectively, the models can truly become things of beauty.

While you can't get your hands on the individual models shown here, Embodi3D does maintain a growing library of 3D printable models for you to download and 3D print yourself. I will put links to some of my favorite downloadable files at the end of this article.
