Due to its potential hazards, the issue of 3D printing guns always affects people's nerves. Earlier this month, US Customs and Border Protection officials arrested Julian Higuera, a US citizen from Phoenix, Arizona, who was trying to enter Mexico with a truck loaded with guns and ammunition. Among these weapons, Customs officers discovered an assault rifle that was semi-automatically converted to fully automatic with 3D printing technology .
The inspectors found that Higuera replaced the lower jaw of the gun with a plastic 3D printing unit, allowing the gun to be fully automated, as long as you pulled the trigger. It is understood that in the United States, it is illegal to privately change weapons to fully automatic, but there are many techniques in this area that make it easy for people to do this, including the first in the world to release 3D printed pistols. Cody Wilson's Ghost Gunner, a small CNC device that can make the AR-15's undercarriage. In fact, the AR-15 is the assault rifle that Higuera modified with 3D printing. The difference between the two is that Higuera is a lower case with plastic 3D printing, while Ghost Gunner uses metal to make parts. The former is not only easier and more convenient, but also difficult to trace.
As we all know, the most worrying thing about 3D printing weapons is that it makes it easy for people to make their own weapons, and it is completely difficult to trace them. This obviously attracts smugglers like Higuera. Although Cody Wilson, who is in court with the US State Department, insists that his online release of open source 3D printing gun design files is a matter of freedom of expression. But one fact that cannot be ignored is that these 3D printing guns and gun parts are often found in the hands of criminals. For the US debate on 3D printing weapons and the grievances of Wilson and the US State Department, please refer to the following reports:
"The problem is not freedom of speech in the country." An official from the US State Department recently said in an interview with the media: "It is to prevent unauthorized foreigners or organizations from acquiring US defense items and potentially sensitive defense manufacturing technologies. Protect the United States because these technologies and items may be used by terrorists or other bad actors to harm Americans, including our overseas service forces."
Recent reports have shown that homemade weapons (though not 3D printed) are being used for violent attacks on the West Bank. According to Nitzan Nurie, the former head of the Israeli government’s fight against terrorism, small-scale terrorists are showing up against 3D. Interest in printing technology. Of course, 3D printing is not the only way to make and modify weapons, but it is definitely the easiest way.
