Materializr

What Materializr is
Materializr is open-source, parametric 3D CAD for makers, built on the OpenCASCADE kernel. It provides sketching with inference snapping, optional dimensions and constraints, SVG import, text outlines, and reference images. Solid tools include push/pull, extrusion, lathe, revolve, loft, booleans, fillet, chamfer, shell, patterns, and direct face editing. Sheet-metal tools, validated internal and external screw threads, and engraving or embossing on flat or curved faces are included. Projects retain editable operation history after reopening, with auto-saved snapshots and crash recovery. It imports and exports formats including STEP, IGES, BREP, STL, glTF, OBJ, 3MF, SVG, DXF, PDF, and .mzr. Its AI Assistant accepts user keys for Anthropic, OpenAI, compatible endpoints, Ollama, or LM Studio; local endpoints can keep data on the machine. Materializr is free under GPLv3 with no account required, and runs on Linux, macOS, Windows, iPad, and Android.
Who it suits
It suits makers who find beginner CAD tools limiting but professional CAD tools too heavy. Users needing parametric modeling, sheet-metal work, and broad file exchange can use it across supported platforms.
