NASA has made no secret of its ambitions for the technology, suggesting it could even be used to streamline the process of humans becoming an interplanetary species. The space agency has said it intends to look further into the possibility of 3D printing settlements on Mars. Redwire, the company behind the printer, says that the device can be used to create small fixtures and fittings, but added that it could potentially stretch to printing larger parts like landing pads, roads, or even habitats on the lunar surface. the printer will use a human-made “moon stimulant”, a compound similar enough in make-up to lunar regolith to warrant testing. Do you think that it could help humans become an interplanetary species?
