Experimental tools for evidence-driven additive construction
Sunnyday Technologies publishes open project records and early-stage tools intended to make additive-construction decisions easier to inspect and validate.
Current project boundaries
These projects are designed to organize evidence and plan controlled validation. They are not certifications, production systems, project specifications, or substitutes for qualified professional judgment.
- M3-CRETE — an experimental open-hardware reference project. Repository availability does not establish completeness, safety, field readiness, or build performance. Project site.
- Open3DCP — maintainer-authored schema and documentation, not a supplied dataset or ratified standard. Schema site.
- CEMFORGE — early-stage materials decision support, available only where sufficient validated data exists. Outputs require independent review and physical validation. Project site.
- CADCLAW — open-source CAD validation tooling. Results depend on the model, rules, evidence, and reviewer; tool output is not engineering approval. Project site.
Sunnyday's proposed workflow connects candidate formulation, documented process context, experimental hardware, and appropriate testing. This site does not claim that an autonomous predict-print-test training loop is operating today.
