3D Printing an Iron Man Helmet

The first project I've tackled since hacking the 3D printer at school is printing an Iron Man helmet. There are some excellent files available over at the Replica Prop Forum that just need some scaling to fit your head. Since the printer has a 10"x10"x12" build area I did the helmet in three pieces, with the biggest piece taking over 50 hours to print. There were a few hiccups with the new black support material mixing in with the red model material, but nothing that some paint won't hide.
