What is a 3MF file?
3MF (3D Manufacturing Format) is the modern format of 3D printing. It is a compressed package with the models, their units and their position on the plate, and slicers also use it to save whole projects.
Unlike STL, it stores the units, so models always open at the right size, and it takes much less space.
Bambu Studio and Orca Slicer projects
Bambu Studio and Orca Slicer keep each part in a separate file inside the 3MF. The viewer reads them all and places them as in the project. Colors, painted areas and print settings are not shown.
Frequently asked questions
Is this 3MF viewer free?
Yes. You can open, view and measure 3MF files for free, with no account and no limits on normal use.
Are my files uploaded to a server?
No. The 3MF file is opened entirely in your browser and never leaves your device.
Can I open Bambu Studio and PrusaSlicer projects?
Yes. Projects from Bambu Studio, Orca Slicer, PrusaSlicer and Cura open with all the models of the plate.
Can I convert the 3MF to STL?
Yes. Use the 3MF to STL converter to download every model of the plate in one STL.
Why are the colors not shown?
The viewer shows the geometry with a color of your choice. Filament colors and painted areas are slicer settings and are not loaded.
