I would like to paint everything with Rustoleum eventually, but my company has kind of hijacked this project in order to show off the capabilities of 3D printing, so it will remain unpainted for now. Also, there was a ton of support material since none of these things had good printing surfaces. It took so long because of the fine layers, which really weren't necessary. I estimate the total print time at about 120 hours. Red pieces were printed on an Ultimaker 2 at 0.1 mm layers, and the gold ones were done on a WASP 40 70 at 0.2 mm layers. Its semi-translucent, so you can see the infill pattern (picture doesn't really capture this). I printed it with MatterHackers' pro series red PLA and standard series gold PLA. Its not really obvious where the smaller pieces go, so I also included a Blender file of the fully assembled helmet, so you can see how it all fits together. I'm reposting the files here (with permission) so that you don't have to deal with downloading them from 4shared. It also has some excellent detail in the mouth area.
I did a lot of digging and although this model has been around a while, it still seems to be the community favorite for 3D printing. The helmet model was designed by drumguy560 on the Replica Prop Forums.
