Nasa to test 3-D printer as flying supply factory in space
Launch next year to test how device does in creating objects from spools of plastic strands, with hopes it will reduce need to load up on supplies
Nasa is preparing to launch into space next year a 3-D printer, a toaster-sized device 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.
Any time we realise we can 3-D print something in space, it's like Christmas
On earth, doctors already use them to make replacement joints and artists use them to build exquisite jewellery. 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 realise 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."
The spools of plastic could eventually replace racks of extra instruments and hardware, although the upcoming mission is just a demonstration printing job.
"If you want to be adaptable, you have to be able to design and manufacture on the fly, and that's where 3-D printing in space comes in," said Dave Korsmeyer, director of engineering at Nasa's Ames Research Centre at Moffett Field, about 55 kilometres south of San Francisco.
For the first 3-D printer in space test slated for autumn next year, Nasa had more than a dozen machines to choose from.
