I've tried pepakura and I simply don't have the time/skills/patience for it lol.

I'd like to try 3d printing some kid to adult size costumes for halloween/party type use.

I have zero knowledge about 3d printing at this point. What size printer would I need to do stuff like Ironman costumes, etc?

What type of material would I be printing with?

What kind of ballpark figure are we looking at cost wise to print something along the lines of an Ironman get-up? In my research I see everything from some sorts of plastic materials being used to I think titanium from Mythbusters lol? Obviously I'm looking at using plastic/cheap.

Any general guidance just to figure out where to get started in researching this stuff would be greatly appreciated.
