Why is 3MF superior to STL for 3D printing?

Unlike STL, which only defines raw surface triangles with no scale or color data, 3MF stores precise physical units, multi-material specifications, color maps, texture coordinates, and even internal structural lattices. It is also highly compressed and less prone to mesh errors like self-intersections or holes.

Who supports and maintains the 3MF format?

The 3MF Consortium, a collaborative joint industry project composed of leading CAD developers, 3D printer manufacturers, and material companies, governs and continuously improves the open 3MF specification.

Can I use 3MF files in standard CAD and slicer programs?

Yes. Almost all modern 3D CAD platforms (like SolidWorks, Fusion 360) and standard slicers (such as PrusaSlicer, Bambu Studio, and Cura) fully support 3MF as a primary import and export format for 3D printing workflows.

Software That Opens & Edits 3MF Files (4 Tools, 2026)

The 3D Manufacturing Format (3MF) is the modern, open-standard file format designed specifically for additive manufacturing and 3D printing. Developed by the 3MF Consortium (which includes Autodesk, Microsoft, HP, and UltiMaker), 3MF addresses the severe limitations of the legacy STL format. It is a clean, XML-based format that packs full scene geometry, scale units, color gradients, materials, textures, and internal lattice structures into a single compressed archive. Below are the tools in our catalog that support importing, exporting, or slicing 3MF files.

3MF Multi-Material Printing Specifications

Voxel and Gradients

3MF files support voxel-based color gradients. Verify your slicer supports gradient infills to utilize advanced physical shading.

Native Lattice Structures

Lighter structures can be mathematically generated without huge STL file sizes, as 3MF stores lattice nodes directly in XML syntax.

Multi-material Tool Offset

Store distinct physical extruder designations inside the 3MF package to cleanly map dual or quad printhead color changes.
