See the printer at the University of Southern California Viterbi School of Engineering. I worked in Dr. Khoshnevis' lab as an undergraduate there 10 years ago.

See the printer at the University of Southern California Viterbi School of Engineering. I worked in Dr. Khoshnevis' lab as an undergraduate there 10 years ago.

The cool part the BBC story leaves out is that they print with material that simulates what the science community anticipates martian and lunar soil will be like!
