Sunnyday Technologies
Printable Concrete.
Sunnyday develops 3D printable concrete from local materials and advanced data analysis grounded in measured performance, helping teams turn regional resources into traceable candidate mixes for projects on Earth and beyond.
Products and platforms
One company, three connected pieces.
Each platform has a clear role. Together they support a repeatable path from candidate formulation to printed specimen to measured result.
CEMFORGE
Concrete mix decision support for 3D construction, local material sourcing, and LOGiMIX project reports where sufficient validated data is available.
PrintM3-CRETE
Open-source 3D concrete printer development focused on accessible research, documented process parameters, and modifiable hardware.
ProveValidation Workflows
Physical testing, thermal observation, mix records, and structured data capture for closing the gap between model prediction and real behavior.
Why this matters
In 3DCP, the printer is part of the material system.
Composition alone is not enough.
Layer height, print speed, open time, equipment geometry, curing, and specimen orientation can change measured performance. Sunnyday treats those variables as first-class data rather than background noise.
The loop creates better records.
A useful validation cycle records the mix, the process, and the test result together. That gives engineers, researchers, and models a clearer basis for the next decision.
Outputs remain decision support.
CEMFORGE and LOGiMIX reports are designed to guide candidate selection and validation planning. Final engineering decisions still require project-specific review and physical validation.
Who we build for
Useful to people doing real work.
Sunnyday is aimed at teams that need better formulation intelligence without pretending construction materials can skip validation.
Process-aware 3DCP studies
Accessible hardware, structured data, and formulation baselines for labs studying printable cementitious materials.
Project-specific mix decisions
Early-stage formulation screening, supplier context, and validation planning for construction teams evaluating 3DCP applications.
Data and deployment paths
Collaborations around Open3DCP records, printable material systems, and validation workflows for emerging construction methods.
