Sorry. That is illegal. You cannot transfer a gun without a serial number.
I particularly love the "less guns == less gun crime" arguments. This is like saying that a lot of race cars are red, so let's ban red cars to make the streets safer. After a decade, the number of car deaths due to red cars is reduced to nearly zero, so you loudly trumped the fact that the streets are safe from red cars!
So reducing gun crime is an admirable goal is you would hate to have a loved one shot to death, but not bothered so much if they are bludgeoned or stabbed to death.
Point in case: I ran the numbers for Australia myself (even adjusted for population). Since the have almost banned all guns, gun deaths have gone WAY down. However, stabbings have gone up. The net effect is that overall violent crime is up by 40%, while murders went down a little. For every single person in Australia NOT killed, there were approximately 656 more people subject to assault or sexual assault. Yet people laud this country as being a great model for gun control. No thanks.
DETAILS: All crime numbers came from the Australian government, years 1995 and 2007 (last year I could find numbers for). Population numbers were approximate to 1,000 for 2007, approximate to 100,000 for 1995.
There are a lot of open-source printers out there. Security mechanisms??? Look up "open source" and show me what security mechanisms can withstand that...
Also, what "security mechanisms" are built into printers? I remember that some yellow dots would be added as kind of a serial number to know which printer made the print a few years ago. Great for proving guilt after the fact, but useless for actually stopping anything.
Oh, and printer software is supposed to magically know that this hollow tube is actually a barrel and not a drinking straw?
Ever heard of CSS? Breaking that was a new technology once. Copying a recipe is isn't new. Coming up with the recipe is.
Copying a recipe for a liberator pistol is not new either.
Please use logic. It has been proven to work.
Have you even heard of a "3D" printer? They will only get better and more affordable. It is already illegal to sell a gun that you made yourself unless you are a licensed manufacturer. So, there are only two types of people that can legally manufacture guns at all:
1) Real companies who file the paperwork and pay their taxes. And a "real" business would not dare sell an all-plastic gun because of liability issues (both "getting past a metal detector" suits as well as "this thing blew up in my face" suits).
2) It is perfectly legal to make a gun for your own use. However, you cannot legally sell or transfer the gun to another person. After you die, it must be destroyed.
If an enterprising criminal wants to make a bunch of 3D printed guns and sell them, he is ALREADY breaking the law, no matter if they have metal or not. Once again, honest people do not need this law, and criminals will not obey it.
Oh, wait. Is this the "magic" law that criminals will suddenly start obeying?
Ummm. It is already completely illegal to sell a gun without being a licenses manufacturer (read "company with deep pockets). Nobody in their right mind would actually sell a plastic gun due to the liability issues involved. Gets smuggled past a metal detector = massive law suits from relatives of victims = no more company.
First, the law was first passed once the first Glocks came out with a polymer frame. All Glocks have been VERY detectible with any metal detector, as the barrel and slide are all solid metal. So this law was passed out of complete ignorance and an irrational fear for something that, quite simply, was not a problem in the first place. Yes, the law makers that want to tightly regulate guns do not actually know much about them -- what a surprise.
Now, this law is trying to be applied to home printers. Really, all you will have to do is buy the printer and set it up. Download the design files, and run them through the printer. Add ammo and shoot. Assuming that your printer is good enough, and that the files are formatted for your particular model of printer, then making your own gun should be pretty easy -- well within the reach of anybody with a few thousand to blow on a printer. Currently, there might be software issues, but I am sure that printing will get easier as time goes on, not harder.
As to there being little public benefit in plastic guns, there is little benefit to the law itself. People who intend to do bad things with guns are not going to be stopped by yet another law. Honest citizens will do anything wrong even with a plastic gun.
Stopping a technology from being created? Yup. That has worked out quite well in the past. Look at the DMCA. Stopped piracy cold, with absolutely no bad effect at all. I sure am glad that nobody has managed to cook up crystal meth in their own home because the laws clearly make trying to do this with, say, an empty soda bottle are illegal. Explosives are also illegal to play with, so nobody has figured out how to use a pressure cooker to make a bomb. I feel safer already.
This law is like trying to stop rape by making penises illegal.
Now, back in the real world, criminalizing objects rather than behavior only hurts the honest citizens, while doing nothing to stop the real criminals.
First, let's assume that we can categorize people into two categories: honest and criminal.
A ban on "plastic" guns from a 3D printer will do exactly what?
1) It will stop the honest people from making their own 3D printed guns. These are the people who obey the law. Since these people are the ones who obey the law, who cares if they have a plastic gun? They will not do anything bad anyways. For the record, the number of guns used in crimes is something like 0.001% of the total guns out there. Similar argument for gun owners.
2) If a criminal wants to commit crimes with a 3D printed gun, do you really think that they will actually obey the law banning plastic guns? If so, you are a special kind of stupid.
So, this law will do absolutely NOTHING to stop crime with "plastic guns" that can be printed in your own home.
I should also like to point out that even a plastic gun will NOT shoot plastic ammunition. Bullets are made of metal -- and should be readily detected by any decent metal detector.
