I'm, sure the process starts with detailed CAD drawings, so I am assuming the operator simply selects a scale and sends it to Start printing. A 1/12 scale set of the '50 Cal. Would be nice also.
If this is real (no reason to doubt it, as it appeared on PMMS), and they are reasonably priced, then they will be a winner !.
I better start saving my pennies !.

I'm 99% sure these are cast in resin the same way as normal resin parts, they have just started from an (expensive) stereolithography rapid prototyped master, which is generated from a 3D modelled CAD part. The definition is too good for the cheaper 3d printing type of rapid prototyping. The stereolithography part is then cleaned up and used to make silicon moulds in the traditional way. I expect he has modelled the pouring stubs as part of the 3D CAD so he can make those funky prongs rather than a solid block to remove.
They are not individually 3D printed as such, just the master.
