Made In Space nabs Guinness world record for longest-ever 3D-printed object
If you haven't heard of Made in Space, you should.

Part of the challenge of space development and space colonization is the difficulty of bootstrapping technology and civilization. It's clear that compact and flexible manufacturing, like 3D printing is going to be a part of that.
