Iron Man 2 is currently crushing its box office competition, with fans rushing to catch the iconic Marvel comic in his cinematic sequel. Whether you’ve seen the movie or plan on seeing it, one production feat that’s sure to blow your socks off is incredible form-fitting body armor donned by Tony Stark (a.k.a. Iron Man, for the latecomers). But don’t think these are the products of CGI artists or even crafty big-budget costume designers. They are in fact the precision perfect prototypes generated by cutting edge rapid 3D printers. Yes, 3D printers have come a long way!
