If you didn't think that the fact that NASA was about to start 3D printing in space was impressive enough, then maybe the fact that they are working with a company called Made in Space to produce a 3D printer filament recycling system will impress you. That's right, NASA is working with the company to create a system which will allow them to turn fist sized ABS plastic objects back into 1.75mm 3D printer filament. The system would allow them to have a closed loop manufacturing facility where ever their shuttle takes them. More details on NASA's plans can be found here: http://3dprint.com/3559/nasa-made-in...ament-recycle/

NASA is also working on other interesting 3D printing projects with Made in Space as well. More details are at the article about.
