STL Is Obsolete: How 3MF Revolutionizes 3D Printing Workflows
Last Updated: 21 Oct, 2026
3MF vs STL: Why 3MF Could Replace STL for Modern 3D Printing Workflows If you have been involved in 3D printing for more than a few days, you know the routine: finish modeling in your CAD software, click export, choose .STL, import the mesh into your slicer, configure your print settings, and hit print.
For nearly four decades, the STL (Stereolithography) file format has served as the universal lingua franca of additive manufacturing.
