DCC scene in. Slicer mesh out.
A print exit from FBX when you do not want to open Maya. The converter writes binary STL from the imported mesh. It will not repair solids. It will not write FBX. Check scale in the slicer.
Source FBX, target STL, preview the hull, download binary STL.
1
Source is FBX. The File API reads it in this tab. Nothing is posted. Keep it under 80 MB.
2
Binary STL from the FBX mesh.
3
Open in the slicer. Confirm units.
This page is only FBX → STL. Other pairs have their own keep and lose notes so they do not repeat this conversion.
| On this conversion | What happens |
|---|---|
| Keeps | Triangles for a slicer. |
| Drops | Materials, clips, and FBX as an output. |
| Next step | Slice. Keep the FBX for the DCC. |

FBX as the source: Geometry only. Color and clips are dropped. Measured 2026-08-27 by running this converter’s own loaders and exporters headlessly. How every format was measured.
FBX is parsed with the File API. STL is written in memory. Materials, clips, and FBX as an output. That is a format rule, not an upload. Files over 80 MB are refused because RAM is the limit.
A print exit from FBX when you do not want to open Maya. The converter writes binary STL from the imported mesh. It will not repair solids. It will not write FBX. Check scale in the slicer.
Source FBX, target STL, preview the hull, download binary STL. No Blender and no account.
You can convert FBX to STL here, then slice. The browser will not thicken walls or fix holes.
No. STL is triangles. Keep FBX or convert FBX to GLB if you still need a look.
No. FBX is parsed here and STL is written in memory. There is no convert API.
Yes. Open the FBX viewer if you only need to orbit. Convert when the next tool actually wants STL.
Slice. Keep the FBX for the DCC.
