Sunnyday Technologies - open foundations, bounded claims

Tools and reference projects for evidence-driven additive construction

Sunnyday Technologies LLC publishes experimental open hardware, a maintainer-authored public data schema, CAD validation tools, and early-stage materials decision support. These projects are designed to help technical teams organize evidence and plan controlled validation; they are not certifications, project specifications, production systems, or substitutes for qualified professional judgment.

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.
