Convert an FBX file to STL

Drop in an .fbx and get an STL for your slicer, in millimetres and standing upright. Converted on your own machine.

How to convert FBX to STL

Drop your .fbx file onto the panel, or click to browse for it.
The file is read and converted on your own machine. Nothing is uploaded to a server.
Download the STL file. You get binary .stl in millimetres.

From a game or animation model to a print

FBX models are made for screens. They are often several separate meshes, open at the seams, with details like hair and fabric made of single-sided planes. A screen does not care. A slicer does: it needs one closed surface it can fill.

The converter merges every mesh into one STL, placed as in the FBX.
It writes millimetres and stands the model with Z up, so it lands on the bed at its modelled size.
Colour, textures, bones and animation are dropped. STL stores only triangles.

Make it printable

After you convert, run the STL through the STL repair tool. It fills holes and turns reversed triangles, which fixes most game models. Then scale the model in your slicer if you want it bigger or smaller than its modelled size, and add supports under arms, chins and other overhangs.

Your file never leaves your browser

This tool is JavaScript running on your own machine. Your file is read into memory, processed there, and gone when you close the tab. It is never sent to us, so there is no upload, no queue, no retention period, and no account to create. You can disconnect from the network after the page loads and it will still work.

JPEG or PNG, up to 4 images, 18 MB each. We'll generate the angles.

Your first model is $2, refunded in full within 14 days if you do not like it. Try it with a sample photo

Frequently asked

How do I convert FBX to STL for 3D printing?

Drop the .fbx on this page and download the .stl. The converter takes the FBX as centimetres, the default in Blender, Maya and 3ds Max, writes millimetres, and stands the model with Z up, so it lands on your slicer's bed at the size it was modelled. No Blender and no Autodesk account needed.

Will a character or game model print?

It will open in your slicer, but game models are often several separate meshes that overlap or are left open. Run the STL through the STL repair tool first, which fills holes and fixes reversed triangles. Thin details like hair cards and capes rarely print well at small scale.
