I wonder how viable an option this is.
The hardware is expensive as hell. The rig they sold at the place I used to work had the "thing bigger than an 8inch action figure" capability ran $2000 american.
Well I wonder what Beth's lawyers think about this? They aren't known to allow copyright infringement to just slide. But good for the guy and I hope this helps out everyone who wanted a pipboy but couldn't get it.
They sell replica models at Conventions all the time at Sci-Fi prop tables. As long as you're selling it as a prop and not as official merchandise, there's no harm no foul.
Unless you already have a 3D printer, it would be more cost effective to buy from people who can 3D print a model for you. Last time I checked, decent 3D printers cost at least $1500.
The cost of a 3D printer depends a lot on what you are willing to build yourself and if you just want an out of the box print setup (and if you want one that is a consumer product, commercial printer or something industrial. You can build a good quality 3D printer for less than $1000 and one on the cheap for less than $500. One major factor in the cost has to do with what materials you want to use as well. If anyone is interested in building one, the best place to start looking is http://reprap.org .
Pretty sure if someone looked into this very closely, someone was 3D printing these things LONG before Bethesda made their E3 announcement. Granted, they own the IP, but I don't think this was an original gamesas idea....
