[NBC] 3-D printed gun fires 6 shots — then falls apart - Page 7

post #61 of 440
The gun probably broke because the printer was probably an HP....
post #62 of 440
Making a lower receiver with a 3d printer is not very impressive; they sometimes make those out of plastic already. The upper and the barrel are the parts that actually need to be extremely strong.

This is true, but they are usually designed that way from the ground up and are shaped in such a away that the weaker material can take the strain.

This thing looks like they just used the plan for the metal receiver and changed little but the material.

Take a second mortgage to buy a 3d printer in order to make a unreliable gun part or grab a kitchen knife?
The funny thing is that the #d printer is treated like a magical device with which you can make stuff. Where the making of stuff is the important thing. Banning 3d printers because you can make barely functioning parts with them is as stupid is as banning rocks because you can bash it against another rock and make em smaller and easier to throw. (unless you have flint which as far as i know is worse than WMD's)
We're a long way from a 3d printer that can make usefull everyday crimecomitting stuff.

I'm thinking more along the lines of organized criminal groups and people looking to murder without association.
Imagine this situation:
Someone relatively wealthy via dealing in arms and or drugs purchases a 3d printer under the table and downloads the schematic at the local public library. Then produces many of these temporary use weapons that have no serial numbers, and theorhetically no traceable barrel signature (given they are able to eventually craft a barrel as well) The weapon won't be very accurate, but it will still be deadly. Now, instead of having to have a large amount of money to pay for a weapon who has never been fired whose serial numbers have been scraped - you can simply buy a disposable, kill your family members and loved ones because your life sucks and get away with it. In fact you could probably take the used weapon back to the guy you bought it from and he would be more than willing to recycle it for you. Even worse, gang members and teenagers, and people with existing criminal records would have little to no problems getting their hands on these. And it circumvents the firearms manufacturing regulations, there are no serial numbers or documentation saying these weapons exist. This is a nightmare from a law enforcement perspective.

Wow the level of stupid here is off the charts. Who cares if it can last through a whole mag it can fire 6 rounds and that's enough to kill. Plus the people that made this have the download on their site so, anyone right now could print off a whole bunch and go do a lot of bad.

They can print out a bunch, assuming they have a 3D printer, and complete AR15 uppers....

or they could just get illegal AR15 lowers to go with their AR15 upper receiver assemblies that they must already have.

Plastic guns already exist, most of which are easily available to the public in some variation:

This is an absurd and needlessly convoluted fantasy scenario. It might make a good comic book story, after you close the gaping plot holes.

Literally nothing you mention here is made any easier by 3D printing firearms.

Or they could just buy a dozen different guns, and throw each one away after a crime.

Would cost less than the printer, wouldn't be any more illegal than printing off firearms to use for crime.

The whole argument falls apart since the same individual could just buy a CNC and make guns that would last fine and still not have serial numbers. Hell he could even put plastic in it if he wanted. Thus, 3d printers wont change anything from how it is currently.

You can get a desktop CNC for about 2k, small lathe and a drill press would be reasonable as well.

Regular printers can print out step by instructions on how to make a gun with a cheap used CNC; better ban printers while we're at it.
