Can Bambu Studio Open GLB Files? How to Import Them

Bambu Studio is Bambu Lab's slicer for its X1, P1 and A1 printers, and it opens models through File › Import.

Short answer · Convert first

Not directly. Bambu Studio doesn't import GLB, so convert the file to STL first and import the STL.

Getting a GLB file into Bambu Studio

  1. 1Check the fileA GLB is self-contained: geometry, materials and textures are inside the one file, so there is nothing else to copy.
  2. 2Convert GLB to STLDrop the file into our GLB to STL converter. It runs in your browser, so the model never leaves your computer.
  3. 3Import into Bambu StudioFile › Import › Import 3MF/STL/STEP/SVG/OBJ/AMF (Ctrl+I).
  4. 4Check scale and orientationBambu Studio works in millimetres and is Z-up. GLB files are metres by convention, so they normally arrive at the right size.
  5. 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

ShapeYes, always.
Colours and materialsIgnored: Bambu Studio only uses the shape.
TexturesNot used by a slicer.
AnimationBambu Studio doesn't play animation.

Things to watch for

  • Slicers don't read GLB. Converting to STL keeps the printable shape; colours and textures are dropped.
  • Use Lay on Face (F) to put the flattest side on the plate before slicing.

Questions

Does Bambu Studio support GLB files?
Not directly. Bambu Studio doesn't import GLB, so convert the file to STL first and import the STL.
Why is my GLB model the wrong size in Bambu Studio?
GLB files are metres by convention, while Bambu Studio works in millimetres. If a model imports tiny, Bambu Studio offers to convert from inches or metres; accept it or scale by 1000% in the object panel.
What is the best 3D format for Bambu Studio?
3MF and STL are the most reliable choice for Bambu Studio. If you have a choice when exporting, pick 3MF over GLB.
