3D printing in the International Space Station
could reduce the cost and frequency of resupply missions

Nasa plans first 3D printer space launch in 2014
US space agency Nasa
is planning to launch a 3D printer into space next year to help astronauts
manufacture spare parts and tools in zero gravity.
It will be the first
time a 3D printer has been used in space and could help reduce the costs of
future missions.
The device will have
to withstand lift-off vibrations and operate safely in an enclosed space
station environment.
Nasa has chosen
technology start-up Made in Space to make the microwave-sized printer.
"Imagine an
astronaut needing to make a life-or-death repair on the International Space
Station," said Aaron Kemmer, the company's chief executive.
"Rather than
hoping that the necessary parts and tools are on the station already, what if
the parts could be 3D printed when they needed them?"
In 1970, Apollo 13
astronauts had to cobble together a home-made carbon dioxide filter using a
plastic bag, a manual cover and gaffer tape.

A 3D printer might
have solved the problem in minutes and helped them reach the Moon.
"If you want to
be adaptable, you have to be able to design and manufacture on the fly, and
that's where 3D printing in space comes in,'' said Dave Korsmeyer, director of
engineering at Nasa's Ames Research Center.
Nasa is also
experimenting with 3D printing small satellites that could be launched from the
International Space Station and then transmit data to earth.
Additive
manufacturing, as 3D printing is also known, builds up objects layer by layer,
commonly using polymer materials.
But laser-melted
titanium and nickel-chromium powders are now being used to build much stronger
components.
In August, Nasa successfully tested a metal 3D printed rocket component as part of its drive to
reduce the costs of space exploration.
