3MF File Format
3MF (3D Manufacturing Format) is an open-source, XML-based 3D file specification designed by the 3MF Consortium to package 3D geometry, colors, materials, multi-part plate layouts, and printer slicing configurations into a single compressed ZIP archive.
3MF archives carry exact filament weights, print times and plate layouts from the slicer, which is why 3MF quotes are more accurate than STL estimates. Uploading the file reads those values straight into the cost breakdown.

Traditional STL files only store raw triangular surface meshes without color, units, or print orientation. 3MF files retain precise mesh vertex integrity, manifold geometry, unit scaling (millimeters), filament type assignments, and slicer modifier meshes without data loss.
3MF in MakerWorld & Bambu Studio
Modern platforms like MakerWorld and Bambu Studio use 3MF as their standard print profile format. A single 3MF project can contain multiple plates, specific AMS multi-color color assignments, support settings, and exact print time predictions.
Cost Estimating with 3MF
Because 3MF files embed slicer metadata (like slice_info.config and plate G-code), cost calculators can parse exact filament weights and print durations per plate without needing to run heuristic slicing engines.
