Does anyone get Metallurgy, Forging, Heat Treating, Normalizing etc etc and Metal Certs? What are these magic printers gonna give me for a barrel or receiver and how am I gonna have any faith in it when it is esentially a printed casting in terms of porosity?
Freeper Engineering Geeks tell me where I am wrong here....Ditto That suspension arm on a race car or wing spar, I am not gonna trust it out of a printer..
Right now, the existing tech can turn out something on a par with or a bit better tan the Liberator .45 pistol (think I have the name right) that was airdropped behind Nazi lines.
In a few years a tough receiver will be possible. Barrels, I think, will be heat-treated steel for the foreseeable future, possibly machines out of car parts. Metal-lined ceramic barrels are a possibility.
