Meshmixer
Meshmixer is Autodesk's free 3D mesh editing tool for repairing, optimizing and preparing STL, OBJ and other 3D model files before printing or further processing. It is widely used by 3D printing professionals, dental labs, jewelry designers, and medical imaging specialists to automatically fix non-manifold edges, add drainage holes, generate support structures, reduce polygon counts, and perform Boolean operations. The Inspector tool detects and fixes common mesh problems in a single click, while the tree-support generator is specifically designed for resin and SLA printing. Meshmixer remains popular for fast pre-print preparation even though Autodesk transitioned active development to Fusion 360's mesh workspace.
AI Recommendation
1 suggestionMeshmixer is an Intel-only build and Autodesk ended active development years ago, with no native Apple Silicon version ever released. It currently runs on M-series Macs only through Rosetta 2 translation; macOS prompts you to install Rosetta the first time you launch it. However, Apple is removing Rosetta 2 in macOS 28 (September 2028), which means Meshmixer will stop launching entirely on that release. If you rely on Meshmixer as part of a workflow or curriculum, you should begin planning a migration now. Autodesk recommends Fusion 360 as the successor for ongoing mesh work — Fusion 360 ships natively on Apple Silicon and includes a mesh workspace with similar repair and editing capabilities. Alternatively, if you need a lightweight, free tool specifically for quick mesh fixes and support generation, consider researching open-source alternatives like Blender (which has a full native Apple Silicon build and includes mesh repair and support-generation plugins) or MeshLab. Contact Autodesk directly if you need to confirm whether they plan any last-minute native build or extended Rosetta support for Meshmixer before the September 2028 deadline.
