“... magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles...”
Regarding the magnnesium/silicon [link above] — nano-tech is apparently involved.
Useful for spaceships, planes, & cars to improve safety and fuel efficiency.
Nano-technology is very cutting edge. I asked if 3d printing is somehow involved. I suspect that dovetailing parts will be a revolutionary use of 3d printing, but the thought of having them printed micorscopically had not occured to me before.
