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. 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 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 repo for updates, or contact Sunnyday Technologies directly for consulting or partnership inquiries.
