Sunnyday may provide
Open-source design references and, only if separately offered and quoted, selected components, documentation, software access, or scoped support. Availability and suitability are not established by this page.
Professional Use Boundary
Not a consumer product.
M3-CRETE is intended for qualified technical teams in controlled R&D, laboratory, or supervised institutional settings. It is not a consumer product, hobby kit, finished machine, certified construction printer, validated field-use system, or structural concrete production system.
Sunnyday does not provide public AC mains wiring instructions, control-panel build instructions,
facility-connection instructions, safety-rated emergency-stop circuit designs, or code-compliance
instructions. Any electrical power system, control panel, grounding/bonding system, disconnect,
overcurrent protection, emergency-stop power circuit, machine guarding, facility connection,
inspection, certification, field evaluation, or AHJ review must be designed, built, inspected,
and accepted by qualified professionals for the specific installation and intended environment.
Responsibility Split
These boundaries should be confirmed in writing before any paid commitment.
Buyer must provide
Controlled workspace, qualified assembly, local-code review, material testing, machine guarding, training, PPE, lockout/tagout, and operating procedures.
Electrical work
AC mains, high-current distribution, safety-rated circuits, and facility integration are excluded unless separately scoped and performed or reviewed by qualified professionals.
No public page, inquiry response, modeled output, software check, portfolio link, or component list establishes safe operation, mechanical integrity, electrical compliance, material performance, structural adequacy, or project suitability. Those conclusions require configuration-specific professional review and physical evidence.
