NSW Police Commissioner warns of dangers of 3D guns
bkoenig:
Oh, I fully expect that will be possible as well. Maybe not as soon on consumer grade printers but eventually.

The ad claims otherwise. I have no experience with sintered metal or MIM but I can see how the method of melting the metal powder would make little difference in the final properties. The ad gives pictures of parts which are impellers, gears, etc... Parts which are the focal points of high torque, stress and strain.

As if "Government Bans" were really effective on anyone but the really stupid or those who willingly are Law Abiding ..... The only reason the .gov can "govern" is that those "governed" consent to such ........ I'm thinking most are on the verge of "Losing Their Religion" .... and if the Welfare checks ever stop, or even slow down, a solid majority will say "screw it".....

The lockwork of my Colt Trooper is all "sintered iron" and has held up for 30+ years and tens of thousands of rounds .......

Has no one seen the 3D printers that use metal for material?

We can make full 3D printed metal products....the printers are just probably super expensive (have to get a quote just to find out the cost).
There is even a liquid metal that can be printed for flexible metal products being developed for 3D printers.

Any decent machine shop and a bit of know how will make better, more useful guns than a 3D printer (for the moment) .....
