3MF Viewer Online: See Inside Any 3MF File
Open 3MF projects saved by Bambu Studio, Orca Slicer, PrusaSlicer or Cura and check every object on the plate, with its size and volume.
Quick start
- Drop the .3mf file on the viewer, or press “Choose file”.
- Every object in the project loads together. Orbit, pan and zoom to check them.
- Read the size, volume and filament estimate in the info panel.
About the 3MF format
3MF is a newer printing format that can hold several parts, real units, colors and slicer settings in one compressed file. Bambu Lab and Prusa use it by default.
3MF or STL?
A 3MF is usually smaller and more complete than an STL. When a site or tool only takes STL, export one with the STL converter.
Questions & answers
Do you keep a copy of my model?
Never. The file is opened by your own browser and is not sent to any server, which makes the tool safe for commissioned, paid or unreleased models.
Does it cost anything?
No. There is no account to create, no watermark and no limit on how many files you open.
Can I open a Bambu Studio project?
Yes. The geometry of every part on the plate is displayed. Plate layout and print profiles are skipped.
Why does my multicolor model show one color?
The viewer focuses on shape. Pick any display color you like in the View panel.
How do I get an STL from a 3MF?
Load it in the STL converter, choose STL and download.
