The early protos used polymers akin to what's used in a hot glue gun and the intention was to use them as visualization tools...then came stereolithography, a different process than we were using...at the time we thought that it would be eventually possible to print with low temp metals or sinterable materials...but these are not suitable to the production of a muzzle for instance, because of the precision and materials required. Some of these parts would still have to be produced by conventional means. That's my opinion anyway.

Material science is in a different place than it was ten years ago.

It is extremely naive to believe that within a few years the materials will not have have been resolved adequately to permit home users to create serviceable weapons. The 3d printed weapons created to date HAVE included parts produced by conventional means; however, it is silly to assume these hurdles won't be cleared. The well-publicized creation of a .22 caliber pistol six months ago is if nothing else a proof of concept. While only the lower receiver of the weapon was printed, it held up for 200 rounds.

It is a matter of time, and probably not much time. The materials are in demand and will eventually become available.
