MOFFETT FIELD, Calif. (AP) - NASA is preparing to launch a 3-D printer into space next year, a toaster-sized game changer that greatly reduces the need for astronauts to load up with every tool, spare part or supply they might ever need.
The printers would serve as a flying factory of infinite designs, creating objects by extruding layer upon layer of plastic from long strands coiled around large spools. Doctors use them to make replacement joints and artists use them to build exquisite jewelry.
In NASA labs, engineers are 3-D printing small satellites that could shoot out of the Space Station and transmit data to earth, as well as replacement parts and rocket pieces that can survive extreme temperatures.
"Any time we realize we can 3-D print something in space, it's like Christmas," said inventor Andrew Filo, who is consulting with NASA on the project. "You can get rid of concepts like rationing, scarce or irreplaceable."

Project manager Matthew Napoli, left, and director of research and development Michael Snyder test a 3D printer which will eventually be used in space on Monday, Sept. 16, 2013, at Made in Space in Mountain View, Calif. One of the biggest obstacles to space exploration is that you need to bring everything with you: tools, equipment, spare parts, satellites. NASA is working with a Silicon Valley company to make specialized 3D printers that would allow astronauts to produce the things they need on-demand when they're in space, allowing them to travel farther from the Earth.
