I want to share this with you all.
8 yrs ago I use to work for a company that was a prototyping shop.
we made a lot of the stuff that you might be using today.
anyway, when I left and got the job I have now I knew where the field that I was working was headed.
it was 3d rapid prototyping, the industry was just experimenting with metal printing. however, there were
rumors about medical possibilities. Well, now they can and did 3d print handguns,fully functional.

now there is something wonderful, happening. take a look. caution some stuff might be not for the faint of heart.
