The printer adds support for them, or tries to place them mid-air, resulting in whiskers. The CT scan has a lot of noise in it - there are artifacts from the oxygen mask and hoses that were on my face. Then a few years later I re-ran it with a Cura update and had success! I had it done on an industrial machine (with a lot of cleanup). The first time I tried this print, years ago, the prints constantly failed. Here are more specific steps to do this yourself using 3DSlicer, from an article I coordinated on with Luis Ibanez in Volume 42 of Make: magazine: /projects/make-42/3d-print-your-medical-scan If you want to download my own skull, I put the STL on thingiverse: /thing:1935234 I’ve done a lot of prints so far, each time tweaking print angles, support material, etc, to see what results I get. You’ll probably want to play with the settings to get something that works to your liking for this. I’ve printed mine successfully on Ultimaker and Printrbot Play printers. Once set as an STL, you’re able to use a 3D printer slicing software like Cura to slice it into layers that are designed for a 3D printer to create. Be warned, this will likely be a very large file. The menu options on the top of the screen here allow for you to reconfigure the render, rotate it, zoom in and out, and even create video files like the one below.įor 3D printing, however, you’ll want to use the “Export 3D-SR” option, then chose the last option “Export as STL (.stl).” That’s the file type that 3D printer software is most familiar with, and can convert into a printable file.
Or just do skin only! It’s pretty creepy and totally amazing.
There are options for two materials - you can choose to isolate just bone material, or leave the skin on the scan. Most of these go way beyond my understanding of CT imaging, so I suggest that you play around with the rendering options to see what results you get. You can even export this “fly-through” view as a 2D movie file, using the menu option “Movie Export” at the top of the screen.īut for 3D viewing and printing, you’ll want to select the menu bar option “2D/3D” then “3D Surface Rendering.”Ī pop-up box will offer you a lot of options.
You can slide your way through the scan to see your body from one slice to the next - it’s pretty fascinating. Select the set you want to work with.įrom here, it organizes the slices in order. There may be folders for different scans (in my case, I had head scans from different angles, and a torso scan). Next open the software and import your DICOM files. This is a Mac-only software tool an alternative is to use the program 3DSlicer, which works on Mac, Windows, and Linux. I used Osirix to convert the CT scans in their native DICOM format into an STL. Watch my two hour discussion as I extract all the support material from my just-printed skullįirst, get your software.
