How to Make 3D Printed Gun Parts - Step by Step Guide

Table of Contents

Isn’t 3D printing an exciting technology, with so much power to bring almost any design to life. However, a lot of critics feel that such revolutionary inventions should be limited to those who could take proper responsibility for using it for the right cause.

One such 3D file that divided everyone into two perspectives was the 3d printed gun parts. Since the time the design first surfaced, it has always been in talks.

Some believe that such easy access to 3D design for creating a weapon that cannot be traced easily or could pass through metal detectors is completely dangerous.

After the first operational gun got its fame in 2013, a lot of other designers have come up with their own styles and designs. However, it’s still isn’t very acceptable.

Many countries have refined their laws against and in for of 3D printed guns. So far, after making the 3D gun parts designs legal to upload online in the USA, many activists and government organizations are fighting to put this down.

A lot is already happening and we do not know what the future entails. However, as of now, you can find pretty amazing 3d printed gun blueprints on the internet and online repositories.

Some of them are even free to download. So, let us know a bit more about the history of the 3D printed gun parts and how legit it is to print one at home.

A Peep into the History of 3D Printed Gun Parts

Cody Wilson designed the first 3D printed gun parts in 2013 and since then, the trend is only surging. Cody is the founder of the Texas open-source gunsmith organization Defense Distributed.

He is an experienced crypto-anarchist. The guy released the first 3D files for the one-shot pistol. Soon, the 3D file created a huge spark within the 3D printing community, bringing the most unprecedented controversy to date. And, it is still ongoing.

In only two days, the 3D file had 100,000 downloads. Right after which the US Department of State insisted Defense Distributed to turn down the model from the internet. This further turned into a legal battle that the techno-anarchist is still facing by the government forces.

Later, a variety of 3D printed guns were released, however, in the form of a pistol. On the other hand, Defense Distributed developed 3D printable parts that were designed for semi-automatic weapons. Hence, these were confiscated by the police.

With the increase in the surge of popularity of the 3D printed gun parts’ blueprints, available through the internet, these firearms have become available to anyone, irrespective of age, mental condition or any other criteria.

These could be accessed by police as well as criminals alike, without any code of legality. This certainly makes the problem much bigger than we can think of.

Hence, it was not very long that the government of different countries started imposing the laws to stop the circulation of 3D printed gun parts and even the 3D files for the same so openly, through the web.

Either its Australia or Japan or even the USA, the government of every country is trying their best to find a solution to curb the issues that are obvious with allowing sharing of 3D files for 3D printed gun parts yet not affecting the freedom of expression.

There are repositories that freely feature the 3D designs for these guns which could be downloaded for free.

But it won’t be easy to find these online forums so easily because of the surging legalities and laws concerning 3D printed gun accessories and parts. 3D printed gun blueprints do pose a hidden threat that we are yet to uncover.

3D Printer Making a Gun with Thermoplastic

The firearms were available before as well, but not completely designed out of thermoplastic material. These were usually assembled with few components made from a 3D printer.

However, Defense Distributed’s Liberator proved that the gun could be designed completely from a 3D printer. Apart from the metal firing pin along with the actual bullet, for sure, everything else was made of thermoplastic.

After the release of Liberator, Cody has been trying every bit to provide a push to his DIY firearms. It did not take much effort to make the 3D file viral though.

However, with the government’s decision to take off the file from the internet, it did provide his goals, a pullback. Following this, Defense Distributed came up with the Ghost Gunner. This is a desktop CNC milling machine that manufactures guns.

At the beginning of its release, the machine only produced the lower receiver component for an AR-15.

But as you would expect, Cody isn’t going to stop anywhere. He upgraded the software and now the Ghost Gunner is also capable of manufacturing the aluminum frame of an M1911 handgun.

Cody Wilson may feel that the increased accessibility of firearm production would help refine the gun rights, others have a different take on it.

The government and others from the 3D community are worried about the consequences of making the technology available to the wrong people.

Risks Associated with 3D Printable Guns

After the 3D designs for firearms got popularity, the governments from different countries started assessing the risks associated with the same.

The first thing to note is that these weapons created by 3D printers don’t need any identification code such as the serial numbers.

These serial numbers are helpful in tracking down those owning these weapons, helping law enforcement regulate the use of such dangerous weapons. However, these cannot be traced.

And, you do not need to go through any background check before you 3D print it. Hence, you can just go ahead and manufacture a gun using a 3D printer. Hence, the probability of getting these weapons in the hands of criminals rises even more.

The question is, are these loopholes are only after the 3D files trended on the internet? The answer is no.

These loopholes existed since the start and people are engaged in creating guns illegally as well. However, 3D printing did widen that loopholes, providing even easier access to everyone.

Is it Legal to 3D Print Gun Parts?

Soon after realizing the threat hidden behind the freedom of circulating 3d printed gun blueprints, the government from the different parts of the world started acting.

The UK Home Office restricted the creation of 3D printed gun parts in Great Britain. It even made buying and selling of these parts and 3D printed gun accessories illegal. The law passed in 2013 in the UK.

Later in 2015, the Australian parliament of the state of New South Wales also came up with a similar law putting serious prohibition against 3D printed guns.

Naming the law as Firearms and Weapons Prohibition Legislation Amendment Bill 2015, the government penalized physical as well as digital possession of 3D printable guns.

In 2016, California did make a different move though. It did not completely ban the manufacturing of 3D printed guns. However, the law required those doing so, to apply for a serial number from the state Department of Justice.

Singapore has stricter laws around Asia. The possession of 3D printed guns is punishable by death.

China wasn’t behind when it came to regulating rules regarding circulation and 3D printing of guns. In 2017, it urged by passing a law to register with the government who wish to manufacture 3D printed guns.

The law that has attracted the attention of everyone from around the world is the one passed in August 2018. The law allowed Defense Distributed to publish 3D designs for firearms.

The US Department of State decided and waived the restraint order put against Cody Wilson in 2015. Therefore, now, those who are willing to 3D print a gun in the USA can easily access the digital file online.

How to Create 3D Printed Gun Parts at Home?

There are two ways to go about it. The first one is to do it all by yourself. Or, you can take help from those who have already driven that path before.

After the restrictions were taken off that was put against Cody Wilson, the internet flooded with 3D printed guns blueprints. You can find a lot of designs to start with. It is easily downloadable and can be edited as required.

Here is what you can do to create a 3D printed gun:

Step 1: If you wish to do it on your own, you would require to create a 3D file for the same. You can use the 3D design software to make that happen.

You can use the one you are used to working with. Do not forget to ensure that the parts are properly designed to fit together.

If you at all think that you are not good enough with 3D designs, why not take help from others.

There are many designs available online. You can download the one you like and make edits to the same. You can even keep the design as it is.

Step 2: Decide to print it with a 3D printer that can provide you the accuracy and right results.

You may not want to 3D print it using a budget 3D printer. Instead, you must do some research and look for the option that could help you create accurate designs.

Step 3: Slice your 3D design. Ensure to use the tips that came along with the downloaded 3D design.

From layer height to all other precise details, you must ensure every setting is in place.

Step 4: Feed the 3D file to the 3D printer and start watching the work happen. It will take some time but the results would be remarkable if your 3D file is correctly designed.

Step 5: Assemble the parts, if any.

Step 6: If you think that the parts aren’t compatible with each other. You may edit the 3D file with a flaw and start printing again for the parts that did not come in their best shape.

Do not forget to check the legalities concerning your country. You may not be allowed to do it. If that is the case, you must make the decision accordingly. Or else, you may have to face consequences that won’t be in your favor.

The Conclusion

3D printing is a very progressive technology. And, as you would know, it could make many things possible that may seem difficult otherwise.

It could even help expedite the manufacturing process of those items that take longer to complete. All these benefits have always put 3D printing at the forefront.

The question is: Can we make sure that the technology is always used for the right cause. Or, can we make sure that the technology does not get into the hands of those who can bring the darker side of 3D printing to life?

All these questions have always bothered those who understand the limitless things that 3D Printing can accomplish.

There are always two sides to everything: the good and the bad. The greater the good, the worse the bad could be. For instance, 3D printed guns could do much worse than good.

If not you, a lot of people have that notion and for the right reasons. That is why it would be difficult to finalize a verdict against the production of 3D printed guns.

Or, even when it comes to legalizing the commercialization of such weapons, government and law enforcement bodies may have to act together to find a solution.

If we have to point in one direction, it could be towards providing better laws that could possibly ensure that the technology is not used for illegal and wrong causes.

But is that completely possible. However, whatever the future would be, and whatever the laws would surface later, as of now, not every country is that strict.

And, if yours is letting you do that, you can experience how it would be like to create 3D printed gun parts at home using your own printer.

3D Printed Pistol | Weapons printed on a 3D printer

With the help of 3D printing, you can make not only harmless souvenirs and trinkets. People did not limit themselves to the necessary mechanisms and things. Legislators were seriously worried, because enterprising designers and inquisitive minds tried to print weapons. And not just a model for cosplay, but a real one, capable of firing live ammunition. But most importantly, they succeeded! Therefore, it was necessary to introduce restrictions at the legislative level for the safety of people. nine0003

Weapons were printed not only by professional devices capable of metal printing. And quite ordinary ones, printing using FDM technology. At the same time, it was possible to print not only prototypes of existing weapon models, but also to develop completely unique models.

3D printed weapons - analogues

The most well-known variants of weapons analogues printed in whole or in part are:

  • Сolt M1911 from Solid Сoncepts
  • Replica of the grizzly .22 hunting rifle made of plastic by a Canadian with the pseudonym "Matthew"
  • Horns for AK 47 and AR-15 - Feinstein from Defense Distributed
  • Parts for AK-47

Concept3d printed Solt M1911 printer. For this, an alloy of chromium, nickel and molybdenum called Inconel 625 was used. 2000 shots can be fired from this weapon. In this case, the number of misfires will be minimal.

A grizzly .22 plastic hunting rifle capable of firing 14 rounds, after which its barrel becomes unusable. The weapon was built through trial and error on a Stratasys Dimension 1200e. nine0003

Other legally restricted options are hybrid systems of existing firearms.

New Designs

Many have gone further and have not tried to print existing models of weapons, but have tried to create new unique models. The most famous among them are:

  • Liberator and Lulz Liberator
  • Shutu-MP1
  • Reprringer Pepperbox

The very first additive pistol was the Liberator. This iconic weapon appeared in 2013. It is completely printed on a Stratasys Dimension SST 3D printer, and its cost is about $10. The drawings of this device were freely available. The disadvantages of this weapon were that it gave a lot of misfires, and was only capable of one shot. The shortcomings have been eliminated in the improved Lulz Liberator model. This plastic pistol is capable of firing up to 8 shots. Now the drawings are removed from the public domain. And the distribution and printing of Liberator is prohibited by law, although you can find a photo of it without problems. nine0003

There is a video on the Internet that shows the tests and characteristics of the combat Shut-MP1. This is a half-printed firearm, meaning it consists of an AR15 receiver and a printed plastic module.

Non-combat printed weapons

This is not about cosplay, but about other options, such as, for example, airsoft guns and air pistols. The printing of such weapons can be carried out on conventional FDM printers. At the same time, there are samples of air rifles printed on 3D printers. This weapon may well be used even in competitions, and it is even capable of outperforming many analogues produced using classical technologies. This rifle has a light weight, a rate of fire comparable to market weapons and is equipped with a comfortable handle and stand. nine0003

So the seal of the weapon is a reality. On the one hand, now everyone can practice as a weapon designer or create a tool for self-defense. But on the other hand, it is important to control the production of firearms, because the security of society directly depends on this.

An American will create a library of blueprints for printable weapons. And it's legal

American amateur gunsmith Cody Wilson, who in 2013 created and tested the world's first 3D-printed pistol, began to create a library of drawings for printable small arms. As Wired writes, the library will work at defcad.com. It is planned to include drawings not only of the weapons developed by Wilson and his company Defense Distributed, but of the "barrels" that other enthusiasts are creating. In the future, any person on the planet, if access to the library is not blocked for him by local authorities, will be able to download any drawing and use it to print small arms or mill some of their parts on a numerically controlled machine. nine0003

The creation of the library became possible after the US authorities agreed to a settlement agreement with Wilson over a lawsuit on the freedom of dissemination of information. After testing the printed pistol The Liberator in 2013 (a single-shot plastic weapon of .380 caliber), Wilson opened the website defcad.com and posted the drawings of this weapon in the public domain. After the number of downloaded them exceeded one hundred thousand, Wilson received a letter from the US State Department demanding to stop the free distribution of drawings. The department said that the enthusiast violated the provisions of the rules of the international circulation of weapons - officials claimed that by laying out the drawings, Wilson was actually exporting weapons without a license. nine0003

Shortly thereafter, the amateur gunsmith closed the site defcad.com, and the founders of The Pirate Bay torrent tracker posted the blueprints of his weapons on their site. In 2015, Wilson sued the US government. He and his lawyers stated in the statement of claim that by demanding the removal of The Liberator drawings from the network, the authorities violated two of the enthusiast's constitutional rights at once - to own weapons and freedom of speech. The latter, it was argued, is the freedom to disseminate information. As a result, in May 2018, the US Department of Justice offered Wislon a settlement agreement, which he accepted. This agreement is recorded in court documents. nine0003

In the settlement agreement, the US Department of Justice recognized the freedom of speech to disseminate information on the Internet, including blueprints for weapons. The department also promised to make appropriate amendments to the rules for the international circulation of weapons - the changed rules will not consider the distribution of drawings for "trunks" with a caliber of less than .50 (with the exception of automatic and using caseless ammunition for firing) as weapons exports. In addition, the circulation of such weapons will be transferred to the jurisdiction of the US Department of Commerce, which will not have the authority to regulate the distribution of technical information (including drawings) about small arms. nine0003

The defcad.com website is already up and running, but only a subscription to informational messages is available on it. When exactly it is planned to launch a library of drawings of printed weapons, Wilson does not specify. Drawings of small arms on the site will be available in CAD format. In addition to printable weapons, the library will also include drawings of some parts that can be made on the Ghost Gunner desktop machine, which is manufactured and sold by Defense Distributed. This milling machine allows you to make ready-made frames for Glock 19 pistols.and M1911 and the lower parts of the receivers of AR-10 and AR-15 self-loading rifles from blanks.

In 2015, the American consulting company ARES published a report on the development, distribution and use of 3D-printed firearms. According to the company, although 3D printing technology is becoming more widespread and more accessible for home use, weapons created on 3D printers will not pose a significant security threat in the foreseeable future.
