Melt 3D

Melt 3D

Melt 3D is free open-source CAD that melts shapes like clay with millimetre accuracy and exports STL/3MF for school 3D printers.

AI integration

A local MCP server (meltcad --mcp) lets Claude/ChatGPT drive the modeller with undo-safe commands, so students go from idea to printable part.
