History was made on November 24th at 9:28pm GMT, when the first 3D printer built to operate in space successfully manufactured its first part on the International Space Station (ISS). This is the first time that hardware has been additively manufactured in space, as opposed to launching it from Earth.

“When the first human fashioned a tool from a rock, it couldn’t have been conceived that one day we’d be replicating the same fundamental idea in space,” said Aaron Kemmer, CEO of Made In Space, Inc. “We look at the operation of the 3D printer as a transformative moment, not just for space development, but for the capability of our species to live away from Earth.”
 
The first part made in space is a functional part of the printer itself - a faceplate for its own extruder printhead. “This ‘First Print’ serves to demonstrate the potential of the technology to produce replacement parts on demand if a critical component fails in space,” said Jason Dunn, Chief Technical Officer for Made In Space.
 
For the entirety of the space program, tools and parts have been built on Earth and required a rocket to get to space. The presence of a 3D printer onboard the ISS will allow hardware designs to be made on Earth and then digitally beamed to the space station, where the physical object will be created in a matter of hours. “For the first time, it’s no longer true that rockets are the only way to send hardware to space,” said Mike Chen, Chief Strategy Officer for Made In Space.
 
The “3D Printing in Zero-Gravity Experiment” is a technology demonstration intended to learn about additive manufacturing processes in reduced gravity. The experiment is being jointly conducted by NASA’s Marshall Space Flight Center (MSFC) and Made In Space, which designed and built the unique 3D printer for NASA through their Small Business Innovation Research (SBIR) program. The printer was delivered to the ISS in September 2014, and on November 17th astronauts installed it in the station’s Microgravity Science Glovebox.
