The result, hopefully, will be a complete physical copy of the digital file. Depending on the size of the part, the type of material being used and the model of 3D printer, this process can take several hours.

Because an FDM 3D printer is working with liquefied plastic, there are limits to what type of objects can actually be printed. For one, a 3D printer cannot create a complex mechanism like a functional gun all in one piece. Instead, each separate component of the gun needs to be 3D printed individually and then later assembled. Additionally, if the shape of any of these individual components has an overhang of more than about 45 degrees, then in order for the part to be 3D printable it needs to include some kind of support structures that will then need to be removed.

Even then, the geometries of some parts will simply be too complex to 3D print using an FDM 3D printer. These limitations make 3D printing a functional gun very time consuming and difficult, and there is a reason that there has really only been a few truly viable fully-3D printable gun designs.

Liberator (gun) - Wikipedia

The type of materials used with an FDM 3D printer are generally referred to as thermoplastics. They are a type of plastic that become pliable or a highly viscous liquid when heated, and yet when cooled will solidify without becoming weakened or chemically altered in any way. A part made from PLA will probably bend and deform before it breaks or shatters. While ABS is much harder and stronger than PLA, once it reaches its limits it tends to crack and break rather than deform.

The reality is that neither material really lends itself particularly well to something as complex as a gun. The explosive force of firing a bullet is simply too powerful for most thermoplastics to survive.

The Shuty hybrid handgun is made from both metal firearm parts and 3D printed parts. Because these hybrids contain metal parts, they are useless for sneaking past any security and they are bulkier so they would be much more difficult to hide. And again, why build a hybrid gun when you can just go buy a new one?

What You Need to Know About 3D Printed Guns and Why You Don’t Need to Fear them

There is actually a large community of custom gun makers who have the machinery and skill to make any firearm that they could possibly want, and there are not a lot of mass murderers who have used handmade firearms. In fact, a 3D printer and a CNC mill are two very similar technologies. Yes, metal 3D printing technology is real, and yes it can be used to 3D print the parts for a fully functional firearm.

There are several different metal 3D printing processes and technologies, but what they all have in common is price. What I hope all of this illustrates is that making a 3D printed gun is not easy, it is not quick, it is not cheap and it does not result in especially dangerous or deadly weapons. Not only is it cheaper to just buy a real gun in the United States, but it is also probably a lot faster to go buy one, even with any state-mandated waiting periods. Even in countries like the UK, Japan or Germany, which have very strict gun control laws, 3D printed guns have never been used to commit a serious crime or used as a viable alternative to illegally purchased traditional guns.

But so far the people who have the skill and resources to make 3D printed guns are not the people who we need to worry about hurting or killing anyone.

Problems are common at home

Frankly, anyone who brings up 3D printed guns while discussing gun control or curbing mass killings is doing so as a derailing tactic, not because they are relevant to the discussion. It is simply not possible to look at the statistics of gun deaths in our country and ignore the fact that we have a problem with gun violence that needs to be dealt with. The type of guns chosen by people who commit heinous crimes and mass killings are chosen for their ability to kill as many people as possible as quickly as possible, and I hope that at the very least we can all now agree that no one is going to get a weapon like that from a 3D printer.

Does the pistol work?

Yes, it can be fired at least once without damage to the body of the gun or the person at the trigger. Andy Greenberg at Forbes has seen the gun fire multiple times and the video above shows one shot.

First Firing of "Liberator" 3D Printed Gun

Is it a real pistol? This is more of a zip gun than a pistol.

The Gun That Sparked the 3D-Printed Weapons Debate Has an Unexpected WWII History

Zip guns were improvised firearms made of tubes, rubber bands, and nails. Kids fool-hardy enough to shoot one this cohort included my own father who showed me how to make them were promised a second of hair-raising and potentially deadly excitement when they made zip guns out of pipe and rubber.

To fire one, you fitted the cartridge into the pipe and pulled back on the nail attached to the rubber band. If it hit the charger properly the bullet would fire. A similar thing is happening here: a spring-loaded nail is hitting a cartridge. Think of this gun as a controlled explosion generator. Among the opponents is Senator Chuck Schumer from New York, who has demanded the federal government reverse the decision made in favour of Defense Distributed.

But Wilson believes that these concerns are unfounded, because it is not as easy as one might think to simply 3D-print a gun. It's just not the state of the art. Wilson first successfully fired his 3D-printed handgun , The Liberator, in May Once uploaded to the Defense Distributed, its blueprints were downloaded almost , before the government forced their removal, the organisation said at the time.
