Aerospace startup GRU Space has opened reservations for its 2032 lunar hotel, requiring deposits between 250,000 and 1 million dollars. The mission roadmap includes a 2029 demonstration of 3D printing regolith bricks with geopolymers for radiation shielding. This signals a systemic shift where additive manufacturing becomes the primary infrastructure layer for space colonies. Utilizing on-site materials bypasses the prohibitive cost of Earth-to-Moon logistics. 🚀🧱 #3DPrinting #SpaceTech #AM
