M3-CRETE - experimental open hardware
A modifiable concrete-printing reference design for research and development
M3-CRETE is an open-hardware reference project intended to make design files, bill-of-materials information, firmware references, and build documentation inspectable as those artifacts are published in the repository. Repository availability does not establish completeness, manufacturing readiness, performance, safety, or suitability for a particular build.
Current boundary
- Experimental reference design; not a turnkey construction printer.
- Not certified, code-approved, field-proven, jobsite-ready, or validated for structural production.
- No public claim of achieved build envelope, delivered cost, shipping configuration, repeatability, or completed physical test loop is made here.
- Fabrication and use require independent engineering review, machine guarding, electrical and controls review, commissioning, material trials, physical testing, and compliance with applicable requirements.
Important limitation: Public information is educational and informational. It does not establish printability, buildability, pumpability, strength, durability, structural adequacy, safety, code compliance, environmental performance, supplier equivalency, or fitness for a project. Hardware and materials work requires independent design review, hazard analysis, fabrication and commissioning checks, material trials, physical testing, and appropriately qualified professional review.
Data caution: Do not send confidential, personal, export-controlled, safety-critical, or proprietary material through the public site. Data intake begins only after written handling terms are agreed.
