3D Slicer Printing: From Scan to Model
Turning CBCT into a 3D-printable model feels like magic the first time. I printed my first jaw from Slicer in resin — smelled awful, looked amazing.
Preparing the File
Checklist before printing:
Segmentation cleaned and closed
Units verified (mm)
STL exported and checked for holes
Scale confirmed in slicer software
Tip
Meshmixer or Blender can fix leftover gaps quickly.
Printing Workflow
Steps:
Segment jaw or tooth in 3D Slicer.
Export as STL.
Import to printer slicer (Chitubox, Lychee, etc.).
Orient model for minimal supports.
Slice and export G-code.
Print and cure.
| Step | Software | Time | Note |
|---|---|---|---|
| Segmentation | 3D Slicer | 15 min | Core step |
| Export | Slicer | 1 min | Quick |
| Slicing | Chitubox | 5–10 min | Depends on detail |
| Resin Printer | 1–2 h | Standard |
Comparison with Meshmixer
| Feature | 3D Slicer | Meshmixer | Notes |
|---|---|---|---|
| Segmentation | Yes | No | Slicer stronger |
| Support Editing | No | Yes | Meshmixer better |
| Export Options | STL | STL/OBJ | Equal quality |
Pros and Cons
Pros:
Complete scan-to-print workflow
No paid licenses
Works on average PCs
Cons:
No direct printer link
STL needs post-cleanup
Occasional scale mismatch
Conclusion
Slicer takes you from scan to tangible model with minimal tools. A bit rough at first, but once you print your first guide, you’ll never go back to 2D images.
