What Is a 3MF File?

3MF (3D Manufacturing Format) is the modern replacement for STL in 3D printing. Developed by the 3MF Consortium (which includes Microsoft, Autodesk, and HP), it overcomes STL's limitations by natively supporting multiple materials, full color information, model metadata, and assembly structure, all in a single compact file.

3MF has been widely adopted by the 3D printing industry. Bambu Lab's AMS multi-material system, PrusaSlicer, Cura, and most professional 3D printing platforms use 3MF as the primary project format. A 3MF viewer online lets you open these files without the originating slicer application.

ShareCAD's 3MF viewer in browser renders multi-material color assignments and geometry accurately, so clients and collaborators can review a model exactly as it was set up for printing, without needing Bambu Studio, PrusaSlicer, or any other slicer installed.

3MF Viewer Use Cases

Sharing multi-color print projects

Share a Bambu Lab or PrusaSlicer project file with a client for review before printing. They see the full color model in their browser without opening any slicer.

Sending to print services

Upload a 3MF to ShareCAD and share it with a 3D printing service bureau. They confirm geometry and material assignments without a shared slicer install.

Design team reviews

Product teams using 3D printing for prototyping can share 3MF project files with stakeholders for design approval before committing to a print run.

Documentation and archiving

Store 3MF files with full material data in ShareCAD and share view-only links for project records, making the design intent accessible long after print completion.
