Materializr
What it is
Materializr is open-source parametric 3D CAD for makers, built on the OpenCASCADE kernel. It includes sketching tools such as inference snapping, optional dimensions and constraints, SVG import, text outlines, and reference images. Solid modeling tools include push/pull, extrusion, revolve, loft, booleans, fillet, chamfer, shell, patterns, and direct face editing. It also supports validated internal and external screw threads, plus engraving or embossing sketches onto flat or curved faces. Projects retain an editable operation history after saving and reopening, with auto-saved version snapshots and crash recovery. File support includes STEP, IGES, BREP, STL, glTF, OBJ, 3MF, SVG, DXF, PDF, and .mzr. Materializr is free and open source under GPLv3, with no account required. It supports Linux, macOS, Windows, iPad, and Android; the Linux AppImage requires glibc 2.38 or newer, and the macOS release is Apple Silicon only and ad-hoc signed rather than notarized.
For and against
For
- Free and open source under GPLv3.
- No account is required.
- Projects keep editable operation history.
- Supports sheet-metal tools and screw threads.
- Imports and exports a wide range of formats.
Against
- Linux AppImage requires glibc 2.38 or newer.
- macOS release is Apple Silicon only.
- macOS release is not notarized.
- The maker advises saving often because bugs may occur.
The verdict
Materializr offers parametric modeling, retained operation history, and broad file-format support without a paid plan. Check its platform requirements and the maker’s warning that the software is young and may have bugs.
Who it suits
Materializr is described as a middle ground for people who find beginner CAD tools too limited and professional CAD tools too heavy. Its parametric modeling and sheet-metal tools may suit makers working across supported desktop and mobile platforms.
