Despite concerns that weapons made with 3D printers could allow criminals and terrorists to easily create undetectable and undetectable plastic weapons at home, my own experience with 3D production quality control shows that, at least for now, it will be 3D Printed firearms carry many or even more threats to those who try to make and use them.
One firearm expert suggested that even the best 3D-printed guns can fire only “five bullets [before] exploding in your hand”. Weapons with design or sealing defects may explode or be destroyed in the hands of the weapon. the user even one bullet before firing.
Problems are common in 3D printing at home made weapons or parts
Many custom 3D printers encounter various problems that cause errors in the items they create. Sometimes an object becomes detached from the platform on which it is aligned, breaks, or breaks during manufacture. Cons can be much more difficult to spot when the flow of thread – the liquid plastic material
When a bad toy or jewelry breaks, it can be dangerous. A child may be left with parts that may, for example, be suffocated. However, if a weapon broke, the repercussions could be more serious – even fatal. In 2013, agents at the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives tested a 3D printed weapon and found that the quality of the materials and production determined whether the gun would successfully fire multiple bullets during or after the first shot will fall apart.
Home printing also runs the risk of criminals tampering with design files on websites, accidentally posting the wrong designs, or even creating viruses that affect the operation of the 3D printer itself. Hackers can target 3D printing tools for ideological or other reasons or accidentally cause mistakes with attacks that are more common on 3D printing systems.
Does not meet commercial standards
Commercial gun manufacturers review designs, test models, and carry out rigorous inspections to ensure that their firearms are correct. Flaws still appear, but the odds are much less than self-printed weapons.
Home printers were not designed to provide the consistent quality needed to make weapons. They also lack the systems to detect everything that can go wrong and make print guns potentially dangerous.
This doesn’t mean that 3D printing in itself is dangerous. In fact, many companies use 3D printing to make parts where safety is important. Printed spare parts are used in aircraft and for medical devices, patient-only surgical instruments, personalized time-relief drugs, prostheses and hearing aids. Scientists have even suggested printed skeletons for growing or repairing parts of the human body.
Bug fixes, but not finished
Over time, improvements to popular 3D printers can enable the safe manufacture of reliable parts. For example, new technologies could monitor the printing process and the threads used. The group I work with and others have developed methods for evaluating components during and after printing.
Other researchers are developing ways to prevent malicious errors from being added to existing printing instructions and printing more safely.
Currently, however, these advances are being developed and tested in research laboratories not found in mass-produced 3D printers. Today, most of the quality control for 3D printed parts is left to the person operating the printer or the person using the product. Most users lack the technical skills to design or run a suitable test and will likely never learn about them. While the machines were no more sophisticated, there was no guarantee that anything made for them – be it a firearm or some other object – was reliable enough to be used safely.
As someone who uses 3D printing in their work and researches quality assurance technology, I have had the opportunity to find a lot of printing errors and analyze the reasons that cause them. The problem is not with the 3D printing concept, but with the process of creating certain elements. Consumer 3D printers do not always produce high-quality goods, and it is unlikely that ordinary people go through rigorous quality assurance tests before using 3D printed firearms.
