Thefirst 3D printer in spacehoused aboard the International Space Station (ISS) has run off its

first object. The item was a faceplate embossed with "NASA and Made In Space, Inc" and is part

of a NASA effort aimed at producing spare parts for long-range space flights and greatlysimplifying mission logistics.

Built by Made in Space, the additive 3D printer aboard the ISS uses a relatively low-temperatureplastic filament to build up objects one layer at a time, and has been modified to operate in

weightlessness and meet space station safety standards.

The 3D Printing in Zero-G Technology Demonstration that saw the production of the first object

3D-printed in space was carried out by NASA astronaut Barry "Butch" Wilmore, who is the

Expedition 42 commander. On November 17, he removed the printer from storage, installed it,

and ran calibration tests with mission control over about three days. NASA says that the printingprocess itself was controlled from the ground to free the station crew for other tasks.

The first actual printing job was executed by a command from mission control on November 24,

when the printer made a faceplate for its extruder casing. According to NASA, this not only

demonstrated that the printer worked in zero g, but that it could create its own spare parts.

Though the first print was successful, the part adhered to the tray, which may be due to themicrogravity environment. This was not anticipated and NASA says that this effect will be

studied further.

The ultimate goal of the experiment is to determine the feasibility of 3D printing in space as a

way of replacing large stocks of spares with a supply of digital printing files and raw materials to

fabricate parts as needed. To achieve this, getting the printer to make its own replacement parts,or even another printer, is a key capability.

NASA says that it will continue to fine tune the process as calibration tests continue. Meanwhile,the test pieces will be returned to Earth next year for detailed comparison with control objects

printed out on an identical printer on the ground.

"The operation of the 3D printer is a transformative moment in space development," says Aaron

Kemmer, chief executive officer of Made In Space. "We've built a machine that will provide us

with research data needed to develop future 3D printers for the International Space Station andbeyond, revolutionizing space manufacturing. This may change how we approach getting

replacement tools and parts to the space station crew, allowing them to be less reliant on supply

missions from Earth."
