A field-deployable, pallet-scale concrete 3D printer 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 baseline — while pairing with CEMFORGE™ for AI-optimized mix design.
M3-CRETE is designed to run formulations generated by the CEMFORGE™ platform — trained exclusively on 3D-printed cementitious specimen data, generating printability and mechanical property predictions purpose-built for additive construction. The hardware and formulation platform are designed 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.
