About Materializr

Materializr is open-source 3D CAD for makers - the middle ground between dead-simple tools like Tinkercad and full professional suites like FreeCAD. Enough genuine solid modeling to make real parts, without a steep learning curve, a subscription, or an account. Sketch on a plane, pull it into a solid (extrude, revolve, loft, sweep), fillet and chamfer, run boolean operations, cut threads, and edit any step of the history later - even after closing and reopening the project. Sketches export to SVG at 1:1 millimeters for laser cutters and 2.5D CNC. It also imports STEP and IGES, and exports STEP, STL, IGES and glTF. The geometry kernel is OpenCASCADE - real B-rep solids, not meshes.

Privacy and F-Droid

F-Droid builds Materializr from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
