3D printing and manufacturing package workflows
3MF is designed for additive manufacturing workflows and can carry richer package context than a simple STL mesh. Use this viewer page to inspect the model before a print-prep, slicer, manufacturing, or conversion step.
Can I open 3MF files online?
Yes. Next3D can open 3MF files in a browser-based viewer workflow for quick visual inspection.
How is 3MF different from STL?
STL mostly represents mesh geometry, while 3MF can carry richer manufacturing package data for 3D printing workflows.
Can I convert 3MF after viewing it?
Yes. A common next step is converting 3MF to STL when a slicer or manufacturing workflow requires STL compatibility.
