I would also like to know the current advancement of technology and 3d printing...

It'll probably get shot down, but the idea streaked through my mind of a cyborg beserker with cybernetic limbs and essentially advanced 3d printers in the sockets, allowing him to essentially rip off useless/damaged limbs and re-print a new one in the field (it would also fit the idea of taking 200% more damage as the beserker core states). Also the idea of him ripping off his damaged arm and using it to batter someone was quite entertaining. 

Should that idea not fly, I have more reserved and down to earth concepts in mind as well.
