In my experience SLA or ballistic particle prototypes are good to identify "oops" type mistakes and to can serve for low tolerance / low stress parts. From numerous prototypes I have seen, surface finish is poor and material properties aren't on par with an injection molded engineering plastic.
Same strength as like a molded plastic
Just whatever you do, don't print them in one location, then finish/assemble them in another location.... didn't work out too well for the last guys who did that.If the plastic can handle being an AR 15 lower, if you get your manufactur license, you can really crank them out with possibility of high profit, it would pay for itself in no time if people were interested.

The future is nearly here... ready made tools from scrap material, clothes, parts... 3d printing will be of utmost importance to the space program.
For us we can only wait and drool until properly high-tensile metal printing allows us to recreate the guns of the past in our garages. I'd print a 9mm Broomhandle Mauser and just keep going from there. (Manufacturing laws aside etc for a different discussion)
