Can OrcaSlicer Open GLB Files? How to Import Them
OrcaSlicer is a free, open-source slicer forked from Bambu Studio that supports printers from many brands.
Short answer · Convert first
Not directly. OrcaSlicer doesn't import GLB, so convert the file to STL first and import the STL.

- 1Check the fileA GLB is self-contained: geometry, materials and textures are inside the one file, so there is nothing else to copy.
- 2Convert GLB to STLDrop the file into our GLB to STL converter. It runs in your browser, so the model never leaves your computer.
- 3Import into OrcaSlicerFile › Import › Import 3MF/STL/STEP/SVG/OBJ/AMF (Ctrl+I).
- 4Check scale and orientationOrcaSlicer works in millimetres and is Z-up. GLB files are metres by convention, so they normally arrive at the right size.
- 5Place it and sliceLay the flattest face on the plate, confirm the dimensions in the object panel, and slice. Slicers ignore textures and animation.
What comes through
| Shape | Yes, always. |
| Colours and materials | Ignored: OrcaSlicer only uses the shape. |
| Textures | Not used by a slicer. |
| Animation | OrcaSlicer doesn't play animation. |
Things to watch for
- OrcaSlicer doesn't read GLB; convert it to STL.
- Run the built-in calibration prints (flow, pressure advance, temperature) once per filament; they matter more than model tweaks.
Questions
- Does OrcaSlicer support GLB files?
- Not directly. OrcaSlicer doesn't import GLB, so convert the file to STL first and import the STL.
- Why is my GLB model the wrong size in OrcaSlicer?
- GLB files are metres by convention, while OrcaSlicer works in millimetres. Scale the model after importing, then apply the scale before you continue.
- What is the best 3D format for OrcaSlicer?
- 3MF and STL are the most reliable choice for OrcaSlicer. If you have a choice when exporting, pick 3MF over GLB.
