They're using a printer you can buy on Amazon: http://www.amazon.co.uk/Draper-57567-Square-Mouth-Shovel-Fibreglass/dp/B0002GUMDW/ref=sr_1_1?ie=UTF8&qid=1359722298&sr=8-1
Why the hell would you build anything for 4 people? Surely they can live in a big hole with a lid, can't they? This seems more like a job for a mining machine than a 3D printer. Then again, I'm not a rocket scientist, so I don't know what I'm talking about.
