Recently, the US media and Congress have been debating whether 3D printing of firearms should be allowed. However, it was also pointed out that this national debate is actually meaningless, because 3D printing guns are inevitable, and how to deal with them is the first priority.
Whether the pistol is allowed to print is not over yet. Today, 3D printing technology has been widely used in the research and development of US military weapons and equipment. The US military has applied 3D printing technology to assist in the manufacture of pop-up igniter models for missiles, and achieved good results. The US Navy is also seeking to enable robots to "communicate, collaborate, and manufacture" capabilities semi-automatically by implanting 3D printers in robots.
According to a report on May 21 from the American Fun Science website, the US Navy may soon use 3D printing these popular technical tools to disrupt the traditional supply chain and revolutionize the maritime strategy.
Lieutenant General Michael Lenza recently wrote a review of the US Navy ’s use of 3D printing. He believes that this advancement in emerging technology may change the construction and repair of aircraft, ammunition, design of bunkers, food and Ways to cure illnesses and recuperate.
"The ship does not have to carry real accessories, just carry a 3D printer and various powdered raw materials in bags, and download the design drawings of the items to be printed as needed," Lenza wrote.
He said that the future navy can even have floating factory ships, which can accept on-demand print orders and produce complete drones.
Lenza and his colleagues in the US Army believe that printing ammunition is not as far away as people think. Researchers at the 3D printing laboratory of Virginia Tech said that future printers may not only be able to regenerate cartridges, but also their energetic components. Researchers say that 3D printing may even produce better ammunition.
3D printing is sometimes called additive manufacturing, and it can also be used to create better bunkers and other structures in beachheads and forward combat bases.
Lenza pointed out that the military's use of 3D printing to create better prostheses for veterans of the Walter Reed National Military Medical Center proves that this technology has been increasingly recognized.
Lenza also pointed out that experts in the field of regenerative medicine are already using living cells and 3D printers to reconstruct heart and lung tissue, cartilage and bones. Bioprinting can also be used for on-site medical treatment, testing the effects of biochemical substances on the printed lungs or skin, and developing printable medicines and vaccines.
According to the Beijing Daily, the most prominent advantage of 3D printing technology is that it can generate parts of any shape directly from computer graphics data without mechanical processing or any molds, thereby greatly saving the time for industrial samples and greatly shortening the product development cycle. , Increase productivity and reduce production costs. These advantages of 3D printing technology will bring revolutionary new changes to the technical equipment maintenance support in wartime:
One is to use 3D printing technology to print damaged parts in time. In the future information warfare, if the damaged parts need to be replaced on the battlefield at any location, the 3D printer can directly "print" the required parts one by one on the battlefield, and then the technical support personnel can assemble the weapons and equipment. Re-enter the battlefield to regenerate damaged weapons and equipment. It is foreseeable that the 3D printing technology, which represents the new development trend of the manufacturing industry, may in the future subvert the traditional equipment technology maintenance guarantee methods.
The second is that 3D printing technology can reduce the pressure of logistics support. For now, using the same amount of consumables to manufacture parts, 3D printers are three times more productive than traditional methods. During wartime, if there is such a 3D printer on the battlefield, the weapons and equipment consumed on the battlefield can be produced in time, which will greatly reduce the pressure on the rear production and logistics support.
The third is to promptly print out the urgently needed weapons and equipment. Today, AR-15 submachine guns can be "printed" by 3D printing. In the future, small guns and ammunition, as well as warships, aircraft, and tanks, can be quickly manufactured directly by 3D printers, which can quickly supplement combat consumption during wartime.
