Sunnyday is collecting early-access inquiries from qualified technical teams in controlled R&D, laboratory, or supervised institutional settings. This page does not create an order, reservation, purchase agreement, price guarantee, support entitlement, or delivery commitment.
Email is an inquiry channel, not a secure upload portal. Do not include passwords, regulated personal data, export-controlled details, customer-confidential files, or third-party confidential information without a separate written agreement and approved transfer method.
Send enough detail to determine whether a beta conversation is worth scheduling.
Research, education, product development, process testing, or controlled prototyping.
Mechanical, electrical, controls, robotics, or concrete/paste-printing experience.
Workspace, safety practices, electrical responsibility, and expected build timeline.
Reaching out on behalf of a team, through an assistant or AI agent? That is welcome. The same public contact address and a machine-readable screening format are available at m3-crete.com/llms.txt. Follow that format so the inquiry can be reviewed consistently. An agent may contact Sunnyday only when authorized by the person or organization it represents; the email route cannot place an order, accept terms, reserve capacity, approve a design, or make a safety-relevant decision.
