Visualized: NASA's MakerBot Replicator
 

Between this and the Arduino, you'd think NASA's Swamp Works was a hackerspace -- though, perhaps in a sense, the research facility kind of is. And really, between the organization's on-going fascination with the potential of 3D printing and a desire to meet budgetary concerns, we probably shouldn't have been all too shocked to see a first-gen MakerBot Replicator on a table of the former Apollo-testing facility. The printer wasn't actually in use during our visit, and the Hazardous Operation tag could probably be taken to be a bit tongue-in-cheek -- though, when it comes to space travel, you can never be too careful.
