It'll cost you around Ten Grand plus extras for a "plastic" gun maker. With 10 Gs you could buy quite a few high quality steel guns that will last a lifetime, and gain in value. It's just a gimmick, something to do because it can be done.
Or buy urself a CNC machine and do it the right way. Plus there are many other things u can do with the CNC.
3D-Gun printing is for Liberals to use an excuse that firearms can be easily made and obtained. The problem is, they forgot all about how readily available CNC machines are and how VERY often they are used to make weapons.
Nothing more than amusing curiosity that has grabbed the attention of the single minded anti gunners who have neither the desire or intellect to see it as such.
