Meshmixer
Meshmixer is a free 3D mesh editing application from Autodesk designed for editing, repairing, and preparing 3D models for 3D printing. It specialises in STL file manipulation, allowing users to fix geometry errors, hollow out models, scale and position objects, and prepare meshes for manufacturing. The tool is particularly popular with 3D printing enthusiasts, engineers, and design professionals who need to patch broken geometry, combine multiple models, or adapt existing meshes without needing a full CAD suite. It can import and export multiple mesh formats and is widely used as a preprocessing step before sending designs to commercial or home 3D printers.
Suggested Replacements
1 suggestionMeshmixer development has been officially discontinued by Autodesk. The latest version is 3.5, released in 2018, and there is no native Apple Silicon build or any planned updates from the vendor. For Mac users needing to prepare models for 3D printing, consider Fusion 360, which is Autodesk's modern successor and offers native Apple Silicon support with integrated mesh repair and 3D printing preparation tools. Other actively maintained alternatives include Blender (free, open-source, runs natively on M-series Macs with powerful mesh editing tools) or Netfabb Standard (Autodesk's newer web-based repair tool). If you must continue using Meshmixer on an Intel-only Mac, you can still download version 3.5 from Autodesk's website, though it will not receive updates or support for modern macOS versions.
