How can I convert my IFC file to STL?

First, click the "Upload..." button and select your IFC file to upload. Your IFC file will be uploaded to our servers. When the IFC to STL conversion has completed, you can download your STL file right away.

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

Most IFC to STL conversions complete in a few seconds for typical furniture-model files (a few MB to ~100 MB). The pipeline runs in your browser for most format pairs — no upload to a server, no roundtrip latency. For SKP and BLEND 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 IFC 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 IFC to STL work?

In order to successfully convert a IFC formatted file to the STL format, our converter tools will perform several initial checks to ensure the file provided is indeed a IFC 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 IFC 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 Formats

File format information for IFC and STL

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

IFC Format

Extension:IFC

Full Name:Industry Foundation Classes

Type:3D Model

Mime Type:application/octet-stream

Format:Binary

Opens With:BIM Software

IFC (Industry Foundation Classes): An open file format (.ifc) for Building Information Modeling (BIM), used in architecture and construction. It stores detailed building data, including geometry and properties, for interoperability.

IFC Converter Capabilities

When converting 3D model or mesh files using our IFC 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 IFC to STL converter

FurniMesh's IFC 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, no watermark, no per-file size cap enforced by the UI — 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), IFC, DAE, PLY, OFF, 3DS, and 3MF. Use the converter to bridge between any combination — 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).
