3D Printed AR-15 Part Linked to Extreme Right Boogaloo Group - 3DPrint.

When the topic of 3D printing guns comes up, it’s always difficult to know what to do. On the one hand, we can cover it and add to the scaremongering around the topic. Or we can ignore it and let a potentially newsworthy story slip by. However, as the trend has evolved, it may become increasingly difficult to look past it, as demonstrated by a recent criminal complaint filed against a West Virginia resident accused of selling over 600 3D-printed plastic parts that convert semi-automatics into fully automatic rifles.

The FBI has claimed that Timothy Watson used a website, Portablewallhanger.com, to sell what is known as a “drop-in auto sear” that makes it possible to turn an AR-15 semi-automatic assault rifle, legal in the U.S., into an automatic machine gun, banned in the country for over 20 years. The federal investigators suggest that Watson was disguising the device as a wall hook. Once an extra bit of 3D printed plastic was removed, buyers were left with a 3D-printed auto sear.

An Instagram commenter refers to “red coats”, code for the enemy of the Boogaloo Boys. Image courtesy of Wired.

For the over 600 units Watson sold, customers included multiple members of the Boogaloo group, the FBI claims. The far-right movement is the latest manifestation of newer right-wing extremists that have emerged leading up to the 2016 presidential election in the U.S. The group was said to have been responsible for the murder of multiple police officers. The Boogaloos have been involved in inciting violence at racial justice protests that erupted in the U.S. in the summer of 2020 in response to the police murder of George Floyd.

Most alarmingly, among those Boogaloo customers was Steven Carrillo, according to the FBI. Carrillo is accused of shooting Santa Cruz police officers and two Oakland courthouse security guards in May and June, which resulted in the deaths of one police officer and one guard.

The 3D printed auto sear works by preventing the bolt within an AR-15 from stopping when fired. As a bullet is fired from the weapon, the gases within the chamber push the bolt back to retrieve a new round from the magazine. The bolt pushes a spring in the gun’s stock down before propelling forward. The auto sear stops the bolt and causes the hammer to push the firing pin once more. This allows the gun to continue firing without any further pulling of the trigger.

Once the extra black portion is removed, the red hook fits into an AR-15 to convert it into an automatic rifle. Image courtesy of Wired.

As we’ve covered in the past, 3D printed guns have so far posed little threat to the public at large due to the fact that the plastic parts are easily destroyed by the extreme forces of the weapon upon firing. They have been capable of firing but are dangerous to the users for this reason. However, this latest story represents a growing trend in the 3D printing of arms.

A consultancy group called Armament Research Services published a report in March 2020 noting that the current trend for DIY gun enthusiasts has grown to include individual components and not entire weapons. This has resulted in hybrid guns, made up of a combination of 3D printed and traditionally made or off-the-shelf parts, and market-bought weapons with 3D printed receivers. The report notes:

“At present, the material limitations of consumer-grade 3D printers, and the high cost of those small number of industry-grade printers capable of producing objects in metals, means that certain essential pressure-bearing components must either be fabricated from metals using alternative methods or substituted for commercially made parts. In the case of a Glock-series handgun, for example, the frame and magazine body may be printed from PLA while the slide, barrel and trigger would usually be original, factory-made parts. The emergence of other technologies such as ECM and desktop/micro-CNC milling machines have bridged the technological gap, and now mean that viable, capable self-loading hybrid firearms such as the FGC-9 can be produced by the home gunsmith without using any regulated components. Other areas for development, such as the production of 3D-printed ammunition, remain in their infancy.”

The auto sear part itself doesn’t take the stress of the bullets being fired, meaning that it can be used successfully even if made out of plastic. The piece would eventually wear away but could easily be replaced. With the price of industrial-grade polymer printers now dropping, it may be increasingly possible to print an auto sear from materials that can withstand the heat and impact of bullets firing.

In some cases, the 3D printing of guns or gun parts may just be a hobby or a means to procure weapons outside of government control. The Ghost Gunner from Defense Distributed, for instance, was focused specifically on CNC machining the lower receiver for an AR-15 so that it might not be traced by government authorities.

Watson was specifically selling a component that would convert an AR-15 into a fully automatic rifle. U.S. legislation frames the auto sear itself as an automatic weapon, making anyone who 3D prints one a potentially culpable in a federal crime. However, groups like Deterrence Dispensed have released their own files for 3D printable auto sears.

While there may be a plethora of reasons for crafting guns or procuring guns outside of government scrutiny, 3D printable weapons and guns rights activists have seemingly been aligned with the right wing of the country. Ghost guns have been involved in more than one mass shooting in the US since 2013. Just this October, a far-right terrorist in Halle, Germany used a homemade submachine gun to murder two people following an attempt performing a mass shooting at a synagogue.

One of the key creators of the 3D printed gun movement, Cody Wilson, is a self-identified libertarian that has been described as right wing and founded Hatreon, referred to as an “alt-right crowdfunding platform.” Wilson himself was charged with sexually assaulting a minor when he allegedly met a 16-year-old on a site, SugarDaddyMeet.com, and paid her $500 in exchange for sex. This led him to step down as CEO of Defense Distributed, the leading site for 3D printable gun files. However, news of Timothy Watson’s 3D printed auto sears suggests that the far right and the 3D printed gun movement continue to commingle

A screenshot from the Portable Wall Hanger website.

As detailed in a recent Wired article on the subject, the FBI claims that one witness in the case was a Boogaloo member who told the federal agency that he learned of Watson’s product from ads on a Boogaloo Facebook group. Portablewallhanger.com also advertised that it would donate 10 percent of its proceeds to Duncan Lemp, a militia member killed by police in March 2020.

Jon Lewis, a research fellow at the George Washington University Program on Extremism, told Wired:

“To the best of my recollection, there has been very little in the way of tangible evidence that domestic extremist groups have successfully used 3D printing to modify guns, until now. When you have individuals who so strongly support the second amendment—pro-gun, anti-government individuals trying to evade any kind of gun control measure—it makes sense for them to shift to this kind of technology. ”

20 Use Cases for 3D Printing

3D printing has progressed so rapidly in recent years that we will soon stop talking about what can be created using additive manufacturing. It will be easier to mention what cannot be done. Yes, this list will continue to grow rapidly. But for now, let's take a look at some examples showing the wide range of 3D printing possibilities. We warn you in advance: the list is far from complete.

Fruit

A gift for impatient parents

Young parents often experience an irresistible desire to acquire all sorts of items, one way or another related to their child, even if not yet born. The Japanese company Fasotec offers future parents models of unborn babies made from images of real fetuses obtained using magnetic resonance imaging. The finished model consists of two materials - a fetal figurine made of white photopolymer, and a transparent material that imitates the shape of the mother's womb. At around $1,275, the fun isn't cheap, but Fasotec already has some competition. So, 3D Babies offers a similar service for only $200, although the size of the finished model is much smaller, and the quality is not quite on the same level.

Although the desire to get such a model may seem a bit strange, there is a perfectly logical explanation. As it turns out, the idea was originally aimed at giving blind parents the opportunity to "look" at the ultrasound of the unborn child.

Weapons

Functional 3D printed receiver from AR-15 without any numbers

The possibility of 3D printing of weapons has seriously alarmed law enforcement agencies around the world. After all, even simple FDM printers allow you to create all-plastic guns. Although such a weapon is primitive, even a disposable pistol with a single cartridge in the hands of a criminal can cost someone a life, and it is impossible to trace such a weapon. However, there are also people who believe that 3D printing of weapons should be allowed. Thus, the US Constitution gives citizens the right to freely carry weapons, although certain restrictions still apply. The non-profit organization Defense Distributed, which released the Liberator plastic pistol into the public domain, went further by unveiling the design of the lower receiver of the AR-15 carbine. AR-15 is actually a civilian counterpart, even a prototype of the M-16 automatic rifle, which is in service with several countries of the world. The lower part of the receiver bears the registration number - this is the only part of the rifle that cannot be purchased as a spare. Thus, the printing of this part can bypass the need to register weapons. Some countries have already banned the 3D printing of weapons, although it is not entirely clear how to apply this ban in practice.

Clothes

One of Snezhana Gross' designs

Some consumables for 3D printing, especially soft photopolymers, are quite suitable for making clothes and even underwear. The bra in the illustration was laser sintered from nylon. This design from Continuum Fashion aims to showcase the possibilities that 3D printing opens up for couturiers. However, don't think this is an experimental model: the company offers finished products for sale on the Shapeways website.

Russian designers did not bypass the new technology either: Snezhana Gross demonstrated casual wear designs integrating functional 3D printed components.

Art

Easy to print. Take a picture - as lucky

Would you like a replica of the Venus de Milo? No problem, just choose the material and printing method. True, marble is not yet on the menu, but sandstone imitators are already available. Gypsum was one of the first materials for 3D printing. A three-dimensional image of the original can be obtained using a regular photo and then converted to 3D. In addition, more and more 3D scanners have recently appeared on the market, including portable hand-held options that can capture images of large objects. It remains a mere trifle - to agree on a stereo photo session with the security of the Louvre.

Although, if you are too lazy to make digital models yourself, you can always download them.

Products

What's for breakfast?

Although giant hot dogs are still far away, 3D printers have already learned how to print minced meat. An example of this is the Foodini culinary printer, a simple and practical device using syringe extrusion. Moreover, printing is possible not only with minced meat, but also with any pasty product - dough, cheese, tomato puree. The only thing that Foodini is not yet capable of is heat treatment. It is to be expected that soon there will be devices that combine 3D printing with refrigeration units and, say, microwave ovens. Then sci-fi tales of "replicators" can come true. One press of a button, and the device will lay out the desired pizza and bake it to the delight of the user. Just one question: do you like thin dough or fluffy?

Characters

Parts of models used to animate ParaNorman's protagonist

Whether it's a miniature version of a giant robot from a favorite manga, a creepy alien creature from Alien, or a Keanu Reeves action figure (as in a black cape and sunglasses, and with a beard and a sandwich sitting on a bench), 3D printing allows you to create replicas of game and movie characters for the delight of fans. And the fact that such souvenirs can be printed even on household 3D printers opens up great opportunities for those who like to collect such models - after all, not all of them are available for sale. Do you want a model of a rare aircraft? Print it.

And what is most interesting, this application has already had the opposite effect. ParaNorman cartoon characters were still printed. Like the new RoboCop suit. True, inside it was still stuffing from a person. But why stop at simple visualization?

Home Robots

Early Terminator Prototype

The advent of inexpensive Arduino boards made it possible to design a wide variety of electronic devices at home. Here are your own 3D printed robots. You printed the case, inserted the servos and the board, and you have a new au pair. But what about people who do not understand programming or elementary soldering? Scientists from the Massachusetts Institute of Technology are developing a project aimed at automating the design and construction of domestic robots. Ideally, the user will only have to set the necessary functions for the future device, after which the system will compile the required design and send it to print. A few hours later, it will be possible to pick up a ready-made device - a robot-spider for wiping chandeliers or a machine for turning pancakes.

Aviation

3D printed part used in Chinese fifth generation fighter aircraft prototypes

The toy airplanes we have already mentioned. What about real ones? There is also a place for additive manufacturing in the aircraft industry, although here one cannot do without expensive industrial plants capable of creating high-quality parts, including all-metal ones. Leading aircraft manufacturers, including Boeing and Lockheed Martin, are already testing laser sintering and melting technologies for the production of ventilation systems, structural components and even jet engine parts. Chinese engineers, on the other hand, set to work on a real scale, creating installations for the additive production of parts weighing up to 300 tons.

Space

Dragon v2 is Space's latest creation

The space industry is not far behind the aviation industry in its interest in 3D printing. NASA has successfully tested titanium rocket engine nozzles, and a few weeks ago, Elon Musk, the head of the private space company SpaceX, held a presentation of the new Dragon v2 orbiter, which also uses engines with 3D printed parts.

Bioprinting

Biopens can help treat fractures

Vessels, tissues, whole organs - several companies are simultaneously developing the production of organic imitators that are completely similar to natural tissues. Although transplantation of 3D printed organs is still far away, work in this direction is underway. In parallel with the production of organic tissues from scratch, methods are also being developed to restore damaged tissues, such as cartilage or bone. Devices called "biopens" are able to apply living cells to damaged areas, promoting their healing.

Prostheses

Titanium orthopedic prostheses with a porous structure for improved osseointegration

What if the tissues cannot be restored? 3D printing can help with prosthetics. Thus, the Swedish company Arcam creates installations for electron-beam melting, which make it possible to create virtually monolithic metal products, including titanium. Titanium orthopedic prostheses have become one of the most sought-after products created on the devices of this company - according to company statistics, their number exceeds thirty thousand copies.

Not only that, 3D printed limbs can compete with high-tech designs with one difference - their cost cannot be compared. How many people can afford a tens of thousands of dollars of prosthetic hands? How about a $50 fully functional prosthesis? And it's possible.

An even more common application of additive manufacturing is in dental prosthetics. If you have recently had a crown or bridge placed, it is possible that they were cast from models created with a stereolithography printer that prints with photopolymer resins.

Musical instruments

3D printed musical instruments

Guitars? Flutes? Drums? Easy. Broke your oboe - print a new one. Of course, professional musicians can argue: plastic guitar? Not seriously. But who said that all tools have to be made of plastic? The same neck can be printed from wood resin, similar in density to natural wood. You can even print a composite carbon fiber core. And as far as simply decorating your favorite harpsichord, 3D printing can work wonders here. It would be fantasy!

Shoes

Luc Fusaro's stylish trainers

Eight-time world sprint champion Usain Bolt is famous for his love of gold. This includes not only medals, but also cars and even shoes. During his contract with renowned manufacturer Puma, Bolt wore signature gold-plated sneakers. And more recently, engineer and designer Luke Fusaro has taken on the development of sports shoes that Usain would like. Its distinctive feature is its golden color. Oh yes - and it's also designed for 3D printing. The use of additive manufacturing has one important bonus, namely the ability to produce shoes that are precisely tailored to the size and contours of the athlete's foot. Such shoes are produced by laser sintering, although this technology has already had a competitor.

Drugs

3D printing can facilitate the production of mixed drugs and help with drug testing on living tissues often in combination with tissue engineering. Thus, the Organovo company directs its efforts to create artificial human liver tissues to test new drugs for toxicity without risk to human health. But the drugs themselves can also be printed by binding the drugs with a gel material. As a result, we get ordinary-looking pills, but with a complex content of drugs, tailored to a particular patient.
