Printing 3d models of patient bones derived from CT scan results (such a medical study)

  • Tutorial

Task: 3d printing of a part of a bone obtained as a result of X-ray computed tomography (CT)
Materials:
1. Results of X-ray CT of a person (on the disc that is issued after the examination, the results are in the DICOM folder)
Methods:
1. 3D Slicer - to convert DICOM to 3d model, edit the resulting model and export to * .STL
2. Slic3r - slicing
3. Print on RepRap Prusa i3

The results of CT, MRI and, theoretically, any medical research with visualization can traditionally be obtained in the DICOM format, an
invaluable tool for converting DICOM to a 3d model - 3D Slicer.
In this Tutorial: Preparing Data for 3D Printing Using 3D Slicer , we need to describe this action.
If in our:


Already need to make additions. IMPORTANT!
To make the model smoother it makes sense in the Crop Volume before the Crop! just above the Crop button! In the Interpolation Option Input section, select the Input spacing scaling constant parameter for less (I entered 0.25) and select the B-spine Interpolator parameter. The model will turn out to be smooth.

Slicing in Slic3r with a layer height of 0.25, width 220%, with standard speed settings, automatic support temperature HotEnd
245, table 100.
And this is the result after printing for 1h 50 minutes on RepRap Prusa i3 with ABS plastic, colorless, manufacturer FDPlast.
