How can I convert my FBX file to STL?

Click the upload area and select your FBX file. It opens and converts in your browser, so the file is not uploaded. When the FBX to STL conversion has finished, download your STL file right away.

How long does it take to convert my FBX to STL?

Most FBX to STL conversions complete in a few seconds for typical furniture-model files (a few MB; uploads up to 50 MB). The pipeline runs in your browser for most format pairs — no upload to a server, no roundtrip latency. For SKP, BLEND and FBX outputs the conversion runs server-side via the native Blender or SketchUp engine, with a hard 5-minute timeout per conversion; most server-side conversions finish in well under a minute.

What does the FBX to STL conversion preserve?

Materials, UV maps, vertex normals, and scene hierarchy are preserved wherever the STL format supports them. STL is the exception — it is a geometry-only format by design and discards materials and UVs. GLB and GLTF preserve embedded textures inside the file; OBJ produces an accompanying MTL material descriptor; SKP groups components logically with materials applied; BLEND preserves the full Blender scene graph with modifiers.

How does converting FBX to STL work?

In order to successfully convert a FBX formatted file to the STL format, our converter tools will perform several initial checks to ensure the file provided is indeed a FBX file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type.

What if I don't have a FBX file to convert yet?

Browse the FurniMesh 3D furniture library — every model exports natively to STL (visit https://furnimesh.com/library/format/stl/ for the STL catalog). Or generate a custom 3D model from any furniture photo with the Image to 3D AI generator at https://furnimesh.com/image-to-3d/ — output formats include STL natively.

File format information for FBX and STL

Detailed information about the source and target file formats, including their capabilities and specifications.

FBX Format

Extension:FBX

Full Name:Filmbox

Type:3D Model

Mime Type:application/octet-stream

Format:Binary

Opens With:Maya, 3ds Max, Blender

FBX (Filmbox) is a proprietary file format (.fbx) developed by Kaydara and owned by Autodesk since 2006. It is used to provide interoperability between digital content creation applications.

FBX Converter Capabilities

When converting 3D model or mesh files using our FBX converter, we will attempt to convert color materials into a suitable format for use in the converted file.

STL Format

Extension:STL

Full Name:Stereolithography

Type:3D Model

Mime Type:model/stl

Format:Binary

Opens With:3D Printers, Slicing Software

STL (Stereolithography): A file format (.stl) for 3D printing and CAD, representing surface geometry as a mesh of triangles. It's simple, widely supported, but lacks color or texture data.

About the FBX to STL converter

FurniMesh's FBX to STL converter runs entirely in your browser using a WebAssembly glTF/3D-mesh pipeline — your file never leaves your tab, and the conversion completes in seconds for typical furniture-model files. Materials, UV maps, and scene hierarchy are preserved wherever the STL format supports them (note: STL is a geometry-only format and discards materials by design). There's no sign-up (up to 20 conversions a day) and no watermark; files up to 50 MB — practical limits depend on your browser's available memory.

FurniMesh natively outputs four formats — GLB, OBJ, SKP (SketchUp 2017+), and BLEND (Blender 3.0+). Bridge conversion via this converter additionally produces FBX, STL, GLTF, 3DM (Rhino), PLY and OFF, and reads IFC, DAE, 3DS and 3MF files. Use the converter to bridge between supported formats — or skip the conversion step entirely if you don't have a source file yet (the FurniMesh library ships every model in all four native formats pre-rendered).
