11 of the metal parts on the NASA Perseverance Rover were 3d printed. These metal parts will land on will arrive on mars, on February 18th, 2021. Here’s more from SlashGear:
The 3D printing process allows engineers to make unique designs and traits, allowing parts to be produced that are lighter, stronger, and more responsive to heat or cold. The first rover to carry 3D printed parts to Mars’s surface was the Curiosity rover, which has been on the Red Planet since 2012. Curiosity has a 3D printed ceramic part inside of its Sample Analysis at Mars instrument.
Perseverance’s 3D printed components are known as “secondary structures,” which wouldn’t jeopardize the mission if the part should fail to function as intended. NASA officials say that taking additional 3D printed components to Mars is a “huge milestone,” opening the door for more additive manufacturing in the space industry. One of Perseverance’s 3D printing components is the outer shell of the PIXIL instrument intended to seek out signs of fossilized microbial life using x-ray beams directed at rocks.
