A field-deployable, pallet-scale concrete 3D printer based on a scaled CoreXY gantry architecture. Designed for robust performance in dusty construction environments with a lightweight printhead (~1.5 kg) and counterweighted material delivery. Target system cost under $5,000.
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 validated baseline — while pairing with CEMFORGE™ for AI-optimized mix design.
M3-CRETE is designed to run formulations generated by the CEMFORGE™ platform — 8,000+ AI-optimized cementitious composites achieving R² 0.85–0.88 via XGBoost models. The hardware and formulation platform are built to work together.
The project is in active development. Documentation, CAD files, BOM, and build guides are published to the GitHub repository as they are validated. Watch the repo for updates, or contact Sunnyday Technologies directly for consulting or partnership inquiries.
