Versions:
MatterControl 2.22.04.11498, released by MatterHackers, Inc., is an open-source application positioned in the 3D-Printing category that combines CAD design, slicing, and print-job management within a single desktop workspace. Makers load STL, OBJ, or AMF files, create simple geometry with the built-in 3D modeler, orient parts on the virtual build plate, and then generate G-code through an integrated slicer that supports FFF, SLA, and belt-printer kinematics. A customizable support engine, 60-plus filament profiles, and a layer-preview mode let users predict surface finish, structural strength, and print duration before exporting the job to any Marlin, RepRap, or Klipper-powered printer connected via USB, Ethernet, or Wi-Fi. The library system stores previous projects with thumbnails, while the queue manager schedules overnight batches and tracks completion statistics. Educational labs use the same interface to teach design-for-manufacturing concepts, hobbyists rely on its cloud library to re-print proven parts, and small businesses automate serial production through the scripting panel that injects custom start, layer-change, and end G-code. Because the codebase is GPL-licensed, firmware developers fork it to test new motion algorithms and share printer-specific enhancements back to the community repository. MatterControl is available for free on get.nero.com, where downloads are supplied through trusted Windows package sources such as winget, always offering the latest build and enabling batch installation alongside other applications.
