What would you build first if you had a lunar 3D printer?

Lunar architecture sounds simple: print habitats with local regolith. But extreme temperature swings, vacuum curing, and fragile structures make 3D printing on the Moon far from easy. This video explores why nature-inspired designs like bird bones might guide the next generation of space habitats. Could biomimicry be the key to living off Earth ? https://youtu.be/kwRSBcrpyj0?si=NXXZ5CrDV1SjfQ6F
