3MF viewer FAQ
How do I view a 3MF file online?
Unlock 3MF Viewer once and choose the .3mf file to preview compatible geometry in your browser.

Does 3MF Viewer show colors and materials?
Available color and material data may be previewed when it is packaged in a compatible 3MF file; application-specific profiles may not appear.
What is 3MF used for?
3MF is used in modern 3D-printing workflows to package model and production-related information.

This tool accepts the compatible 3MF extension shown in the upload area. Use the dedicated format viewer when a file has a related extension or an application-specific variant.
