NASA engineers pushed the limits of technology by designing a rocket engine injector --a highly complex part that sends propellant into the engine -- with design features that took advantage of 3-D printing. To make the parts, the design was entered into the 3-D printer's computer. The printer then built each part by layering metal powder and fusing it together with a laser, a process known as selective laser melting.
 
now that's what I'm talking about! Enough of this ABS plastic bullshit, if I'm forced to go with that a 3D printer should cost me $200 tops, think inkjet vs laserjet back in the day :D
 
That's some bad ass shit. Sooner our grand kids get off this planet the better.
 
Saw these a few years ago at a trade show. They were "printing" everything from steel car and appliance parts to edible candies.
