# Materializr (open-source app)

> Materializr is a free, open-source app for Android and iOS. Maker 3D CAD - the middle ground between Tinkercad and FreeCAD. It has 142 GitHub stars and is released under the GPL-3.0-or-later license, and you can install it from F-Droid, Google Play and the App Store.

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.
