alt Hacker Newsi mean speed and consistency, compared to manually CnC [crank n curse] cutting, or printing.
if you set up your job so that you print a block of, lets say 4 lower receivers for a stoner style firearm. and you ran a number of printers, you start an arsenal, for a fire team, not just a lonewolf, and that scares people.
You know what’s even faster and cheaper than building a 3d printing gun factory?
Just buying a bunch of lower receivers. There are plenty available for less than $50. Hell, there are companies that sell them in 3 packs. If you are trying to build an arsenal you can just go to a gun store, there’s no limit on how many you can buy at once. If you don’t want the purchase to be background checked go to one of the many states that allow unrestricted private gun sales and go nuts.
