A pallet-scale concrete 3D printer designed for field deployment, based on a scaled Cartesian dual-Y belt-pinion architecture with quad-Z self-tramming. Designed for robust performance in dusty construction environments with a lightweight printhead (~1.5 kg) and V-groove motion system. The open BOM is intended to keep self-sourced component cost under $5,000 where current commodity pricing and substitutions allow.
The concrete 3D printing industry moves faster when hardware isn't a barrier. M3-CRETE is released openly so researchers, universities, and contractors can build, modify, and improve on a published CAD/BOM development baseline — while pairing with CEMFORGE™ for AI-optimized mix design.
M3-CRETE is designed to run formulations generated by the CEMFORGE™ platform — trained on validated 3D-printed cementitious specimen data, generating supported printability and mechanical property predictions where sufficient data is available. The hardware and formulation platform are designed to work together.
The project is in active development. CAD files and BOM are published, with build guides and documentation added to the GitHub repository as they are validated. Watch the repository, open an issue, or start a discussion for design feedback, build reports, or technical questions.
M3-CRETE is not a casual hobby kit, finished certified printer, or jobsite-ready electrical product. It is intended for qualified technical users, labs, schools, R&D teams, and experienced builders. Any AC mains wiring, control-box integration, grounding, disconnects, emergency-stop power circuits, facility connection, inspection, or code compliance work must be performed by qualified personnel, a licensed electrician where required, or a qualified control-panel shop. Public project files identify interfaces and components; they are not AC mains wiring instructions.
