“Made In Space, Redwire, and Bigelow, transfer over,” writes lengthy-time Slashdot reader Dr. Crash. “There’s one more 3D printing in house group — and it is not a startup.”
Mitsubishi Electrical simply went public with a UV-delicate resin specifically made to print in zero-G and in a tough vacuum — as in exterior the airlock.
The polymer is tuned to harden with photo voltaic ultraviolet mild, so no UV lasers wanted (saving energy and launch weight).
Their first purpose? Printing cubesat parabolic dishes in orbit, so a 300mm cubesat may have what appears like a one-meter dish antenna — or the rest that may be freeform-printed.
This “photopolymerization” expertise “particularly addresses the problem of equipping small, cheap spacecraft buses with giant buildings, corresponding to excessive-achieve antenna reflectors,” based on Mitsubishi’s announcement — arguing that it additionally finally “permits on-orbit fabrication of buildings that drastically exceed the size of launch car fairings.”
