The Plan to Put a 3-D Printer With Robot Arms Into Orbit

Space is indifferent to your suffering. And it certainly doesn't care how difficult it is for humans to get stuff done in the void: practical things like screwing in bolts and drinking water and 3-D printing replacement parts. But a company called Made in Space is indifferent to space's indifference. In a first, it's showed that it can 3-D print in a thermal vacuum chamber, which simulates the nastiness of space. It's a milestone in the outfit's ambitious Archinaut program, which hopes to launch a 3-D printer with robot arms into orbit.
