You're comparing a computer which is strictly electronics to a milling capable product.... and you think someone else has bad logic lol
You.re right, circuitry based electronics will always get cheaper. This is not that.
You're comparing a printer for a grand that can make a plastic tie clip, to a printer that is laser machining gears, cylinders, etc. It's not even in the same realm. The components are not the same. the technology is not the same. It's akin to saying well I bought a wood lathe at harbor freight.. I ought to be able to turn my rotors on my car.. they're both lathes after all right? That's what I'm trying to get it. A 3d printer isn't a 3d printer isn't a 3d printer. A $1000 printer will never be able to manufacture a gun. It doesn't, and can't have the capability. Maybe a polymer look a like.. but what's going to be useful for that? Something that will have the ability to precision laser machine and mill will always be way too expensive for you and I to buy.
You do have a valid point about gangs and other cartels and what not. But just the idea that the average gun fanatic is going to manufacture one in his basement is what I'm disputing.
Proof you don't know the technology behind 3D pringint. Most 3D printers use deposition technology like Fusion Deposition Models, CVD (chemical vapor deposition), etc. They basically add a layer at a time. They do NOT etch/cut/laser out the part like a CNC does.
Think of sliced bread but in reverse. You cook a slice of bread at a time then stack them on top each other to make a loaf.
The only type of 3D printing that even uses a laser is one that only uses a laser to sinter a powder turning it into a solid layer. No 3D printer is precision layer cutting like a CNC does.
I actually have worked on and been published years ago on some of these physical processes (chemical vapor deposition and plasma vapor deposition primarily), so I understand the science behind 3D printers. 3D printers and CNC machining are not even close to similar technologies.
Funny thing is, back when we were doing the initial science/math modeling we figured this technology would be HUGE in the formation of miniature microchips...and it has been. We never really thought of the idea of 3D printing.
Also, before you say "but you can't deposit things like metal..." while most 3D printers now only work for polymer materials, when we were doing this in a lab back 15 years ago we were doing it with highly conductive metals like gold, silver, and copper to show its applications in the miniature microchip world.
So yes, metal can be deposited 1 layer at a time, just not as "easy" on the large scale (firearms) yet.
