While 3-D printers are becoming commonplace, nowhere are their benefits more obvious than in the confines of space. Cargo resupply missions to the ISS are routine, but as human spaceflight pushes farther out into deep space, there will be more pressure for self-sufficiency, as resupply missions become more difficult and expensive. That means not only manufacturing supplies, but also conserving and reusing the supplies on hand.
