I built a v1 RepRap about a year and a half ago, and the total cost came in at about $400. The v2 is hopefully going to be released within the next year or two, and it's already been announced that it will be able to print other materials, not just hard plastic.
Be sure to work hard and get lots of overtime. People on welfare want more steaks and free upgrades to smart phones with unlimited data packages.
Sadly I don't have enough experience of working with the materials that you're using, but I have successfully used RepRap to create molds (in pieces that have to be put together, then sanded) that I used for making carbon fiber items and fiber glass molds. I also made a chess set
Sorry for double post, seems like it won't let me edit the last post to add this but....
I just read that the next major set of plans to be made available for 3D printers is for an invisibility cloak. From what I read of how it works, it would only make something "invisible" from certain angles, and right now that "something" is only microwaves, but still, the next step is hilariously obvious; is someone going to manage to combine the two plans to create printable, invisible/semi visible guns?

Make your own invisibility cloak with a 3D printer
