Online 3MF Viewer
Drop a .3mf file to open it in a fast 3D viewer — drag to rotate, scroll to zoom, and inspect the model. Free, instant, and 100% local: your file never leaves the browser.

About the 3MF viewer
- Opens 3MF files — the 3D Manufacturing Format that Bambu Studio, PrusaSlicer, Cura and Windows 3D tools use. A .3mf is a zip package holding the mesh plus print metadata.
- Everything runs on your device with WebGL. There's no upload, no account, and no file-size paywall.
- The viewer renders the model geometry. Some slicer 3MFs (especially multi-plate Bambu files using the production extension) split geometry across internal parts and may show only some of it — the Bambu → Prusa tool flattens those into a single standard 3MF.
- Need to slice or edit it elsewhere? Convert the 3MF to STL or OBJ, or re-pack it for another slicer, using the links by the viewer.
Frequently asked questions
- How do I open a 3MF file online?
- Drop your .3mf file into the box above. It opens instantly in a 3D viewer — drag to rotate, scroll to zoom. Nothing is uploaded; the file is read locally in your browser.
- What is a 3MF file?
- 3MF (3D Manufacturing Format) is a modern 3D-printing file that bundles the model mesh together with print settings and metadata in a single zip-based package. Slicers like Bambu Studio and PrusaSlicer save projects as .3mf.
- Is this 3MF viewer free?
- Yes. It's completely free with no signup, no watermark, and no file-size limit beyond 200MB. The model renders locally with WebGL.
- Why does my Bambu 3MF look incomplete?
- Some Bambu Studio 3MFs use the production extension, which stores geometry across multiple internal files. A plain viewer may render only part of it. Run it through the Bambu → Prusa converter to flatten it into a single standard 3MF that opens everywhere.
- Is my 3MF file uploaded anywhere?
- No. There is no server and no upload. The file is parsed and rendered entirely on your device, and nothing is stored.
- Can I convert the 3MF to STL after viewing it?
- Yes. Flip3D converts 3MF to STL, OBJ, GLB and PLY in the browser. The convert links are next to and below the viewer.
