NASA to Test Parts Printed on ISS

Those 3D-printed objects from the International Space Station arrived at NASA’s Marshall Space Flight Center in Huntsville, AL, on April 6.

Created as part of the 3D Printing in Zero-G Technology Demonstration project, the 3D-printed items will help test the performance of additive manufacturing technology in orbit to help create tools and supplies for lengthier missions as the space agency looks to send manned missions to Mars and beyond.

The printer was installed in the ISS Microgravity Science Glovebox last November. The crew manufactured 21 items based on 14 different designs, including a ratchet wrench. They also produced some calibration coupons.

Prior to launch, NASA used the printer to make an identical set of 21 parts, which will be compared to those manufactured on the space station. Materials engineers will test both samples for durability, strength, and structural stability, in addition to scanning them with an electron microscope. The parts will also be compared to the original CAD models.

The parts printed in space were shipped back to Earth via the SpaceX Dragon in February.

The printer will remain on board the ISS for continued use this year.
