Convert FBX to STL

Free FBX to STL converter. Runs in your browser, so the file never leaves your computer. Preview the model, then download the STL.

Good to know

Characters from Mixamo or a game engine are often in centimeters and Y-up. The pose in the file is what you get; rigs and animation are dropped. Check the model is watertight before printing — the STL repair tool can fix most holes.

How it works

  1. 1Drop your FBX file in the box above. It is read in your browser.
  2. 2Check the preview and the size. If the FBX came in meters or inches, set the scale.
  3. 3Download the STL. It opens in Bambu Studio, PrusaSlicer, and Cura.

About FBX

FBX (Autodesk Filmbox). Autodesk’s exchange format for animation and games. Unity, Unreal, Mixamo, and Maya export it. Rigs and animation are dropped when you print.

Units: Stored in the file. Often centimeters. Up axis: Y. Opens in Blender, Maya, 3ds Max, Unity, and Unreal Engine.

About STL

STL (Stereolithography). The default 3D printing format since 1987: a bare list of triangles. Every slicer reads it, but it has no units, no color, and no parts.

Units: None in the file. Slicers read the numbers as millimeters. Up axis: Z. Opens in Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender.

Questions

Is the FBX to STL converter free?
Yes. You get 3 runs a month without an account. Sign in with your email, free, and there is no limit.
Is my file uploaded?
No. The file is read and converted in your browser. It never reaches our servers.
Will the STL keep colors and materials?
No. STL has no place for colors, materials, and separate parts, so only the shape carries over.
What units is the STL in?
FBX: Stored in the file. Often centimeters. STL: None in the file. Slicers read the numbers as millimeters. The converter does not guess. Use the scale option if the size looks wrong.
How do I open an STL file?
Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender all open STL.
