Can anyone here explain to me, in common terms, exactly what a "3-D printed gun" is. Why is everyone getting so excited about it?
they got 10 .380 rounds out of it before the barrel cracked, no rifling that I know of.
It is printed with a plastic polymer that comes in cassettes it is basically a spool of plastic wire that is fed into a heated chamber (200 degrees or so) and melted and placed based on a cad file. the printers are currently $2300 and up but next month staples will be releasing a $1300 model. The material cassettes are in the $50 range. The printer they used cost them $8000 off of ebay and was a more industrial printer that probably cost $20,000 to begin with. I have had the opportunity to set up one of these printers and watch how they worked.
This pretty much hits the nail on the head. I really don't see why people are making such a big deal of this. Its always been legal for one to make their own gun...and this is plastic yeah, but the ammo is metal, they have a metal firing pin, and they have a chunk of metal to make it legal too. Just people are scared of what theybdont understand. I personally wouldn't trust an all plastic gun.3-D printers are just exactly what it sounds like. They "Print" in 3 dimensions. Some with polymers, some with metal. Basically a powder is sprayed and solidified in a 3 dimensional matrix. I'm not conversant with the exact methods. I assume that heat and or solvents are involved. This gun was produced almost entirely in one of these printers with the exception the firing pin and a chunk of metal to make it "detectable" to meet the ATF requirements of a licensed manufacturer.
This is a big deal really only to the techno geeks. It has always been legal for an individual to make their own guns(at least as far as the ATF is concerned, consult your local and state laws), this is simply a bit cheaper way of doing it, though that may be arguable right now. I have a feeling that the printer capable of this is extremely expensive as of yet. Though the bench top CNC mills are quite capable of producing a serviceable pistol or rifle except for the rifled barrels.
I haven't looked into this too deeply yet. Does anyone know if this pistol is rifled? Has it been tested for longevity/durability at all?
And I don't think Cody Wilson would either. The point is the implications of what's to come. Take a look at their website, DEFCADI personally wouldn't trust an all plastic gun.
- IMO, printing magazines would be be an even bigger challenge to existing laws. While it's easy to buy "high capacity" magazines out of state if you live in a restricted state, all you would need is to have metal springs on hand to create the magazines you would need. I would hope that this fact alone would start to break down restrictive magazine laws.No longer will it be necessary to have the know how and expensive tools (beyond the printer) to build a devastating firearm, and no longer is it the case that it's even remotely possible to ban magazines. At any level, gun laws are going to be challenged by this.
Ceramics? The functional "printed gun" is a milestone in a new tchnology. Not practicle, but an acheivement none the less. The time will come when most any product currently made by machinists can be duplicated on a "printer", but current technology creates a replica in weak plastics or crumbly metal powders, best suited for casting patterns. That method can be used to make a metal gun parts at home that will work with a little filing. Metals can be smelted in a microwave in small batches.Never mind the fact that they still have to sneak bullets through a detector somehow.
