ISS to host zero-gravity 3D-printing experiment

NASA is preparing to launch equipment for the first 3D microgravity printing experiment to the International Space Station.

In preparation for a future where parts and tools can be printed on demand in space, NASA and Made in Space, of Mountain View, Califronia, will carry out the 3D-Printing in Zero G Experiment (3D Print), which if successful it will be the first device to manufacture parts in space.

3D Print will use extrusion additive manufacturing, which builds objects, layer by layer, out of polymers and other materials and the 3D Print hardware is scheduled to be certified and ready for launch to the space station next year.

"As NASA ventures further into space, whether redirecting an asteroid or sending humans to Mars, we'll need transformative technology to reduce cargo weight and volume," NASA administrator Charles Bolden said during a recent tour of the agency's Ames Research Center at Moffett Field, California.

"In the future, perhaps astronauts will be able to print the tools or components they need while in space."

3D-printing technology holds huge potential for future space exploration, with hopes it will one day allow an entire spacecraft to be manufactured in space, eliminating design constraints caused by the challenges and mass constraints of launching from Earth.

"The president's Advanced Manufacturing Initiative cites additive manufacturing, or 3D-printing, as one of the key technologies that will keep US companies competitive and maintain world leadership in our new global technology economy," says Michael Gazarik, NASA's associate administrator for space technology in Washington.

"We're taking that technology to new heights, by working with Made in Space to test 3D-printing aboard the space station. Taking advantage of our orbiting national laboratory, we'll be able to test new manufacturing techniques that benefit our astronauts and America's technology development pipeline."

In addition to manufacturing spacecraft designs in orbit, 3D printers also could work with robotic systems to create tools and habitats needed for human missions to Mars and other planetary destinations.

Housing and laboratories could be fabricated by robots using printed building blocks that take advantage of in-situ resources, such as soil or minerals. Astronauts on long-duration space missions also could print and recycle tools as they are needed, saving mass, volume and resources.

"The 3-D Print experiment with NASA is a step towards the future," says Aaron Kemmer, CEO of Made in Space. "The ability to 3-D print parts and tools on demand greatly increases the reliability and safety of space missions while also dropping the cost by orders of magnitude.

“The first printers will start by building test items, such as computer component boards, and will then build a broad range of parts, such as tools and science equipment."

Made in Space previously worked with NASA through the agency's Flight Opportunities Program to test its prototype 3D Print additive manufacturing equipment on suborbital simulated microgravity flights.
