3D Printed Parts on the Mars Perseverance Rover: The Cool Parts Show #23

An instrument system that is part of NASA’s Mars Perseverance Rover, scheduled to land on Mars soon after we post this episode, uses components 3D printed through electron beam melting (EBM) by Carpenter Additive. The titanium parts were challenging to produce because of a design relying on internal lattices and other delicate features to achieve high strength despite minimal material use in accordance with a strict mass budget. As this episode of The Cool Parts Show describes, NASA engineers had to design these components without considering how they might be made. The resulting manufacturing process demands not just 3D printing, but also a sequence of postprocessing steps including chemical milling.
See replicas of the Perseverance additive manufactured parts in this episode, which we filmed while Perseverance was in the final days of its approach to Mars.

really interesting how you can offload constraints from design to manufacturing, especially when you said at the start the constrain envelope was already so large for design! amazing content, many thanks and looking forward to more!

Super cool! And super complicated... Really interesting episode Peter and Stephanie!!!
