MarkWhittington writes: "t has been a truism among space planners that future space settlers will have to build things on other worlds out of as much local materials as possible, saving the cost of transporting things from Earth to the moon or Mars. Two professors at the School of Mechanical and Materials Engineering at Washington State University have taken a step forward toward developing that technology using laser enabled 3D printing using simulated moon rocks to create simple objects."
"A complex system that works is invariably found to have evolved from a simple
system that worked."
