What this tool does
Use this 3MF viewer to inspect 3MF geometry locally before converting or printing.
When this tool fits
Best when inspecting 3MF geometry before slicing
the viewer confirms that the model parses and that dimensions look right.
Best when checking whether conversion is safe
mesh stats help you decide before moving to the 3MF to STL converter.
Best when production metadata is secondary
the page focuses on mesh geometry rather than full 3MF job metadata.
How to use it
- 1
Upload a 3MF file
Choose a .3mf file from your device.
- 2
Inspect parsed geometry
Check the preview, mesh count, triangle count, and model size.
- 3
Decide the next step
Use the main 3MF to STL converter if you need STL export controls.

FAQ
Can I convert from here?
Use the main 3MF to STL converter when you want STL export controls.
Does the viewer show 3MF colors and materials?
The viewer is focused on mesh geometry. Colors, materials, and production metadata may not be fully visualized.
Why check 3MF before STL export?
A preview lets you confirm the parsed model size and triangle count before exporting mesh-only STL output.
