3D printing seems to be omnipotent, whether in commercial, research, industry, or in the medical, military or aerospace technology, an increasing number of 3D printing products are trying to change our lives, to make it more convenient and efficient. However, there are some things later in the use of 3D printing becomes more frightening them, for example, led to a variety of 3D print pistol weapon.
May 8, 2014, Japanese police arrested a man named Imura work righteousness Friends 27-year-old university employee, because he was suspected of illegal possession of two bullets can be fired true 3D printed gun, and Imura from foreign web sites on easy access to 3D print guns drawings. As of May 2013, the world's first 3D printed gun making CAD files on the network has accumulated downloaded more than 100,000 times, even with US senators demanded an end to provide relevant documents on the Internet, but still can not prevent all kinds of 3D Printing development of the gun. It is even more panic, because the relationship between materials, the current security equipment can not detect a good 3D print weapons, firearms if similar equipment is on board the aircraft, the consequences could be disastrous.
So, 3D printed gun is a step by step how to develop it?
1. The world's first 3D print pistol
The world's first 3D print pistol, the 25-year-old University of Texas student Cody Wilson made by Defense Distributed founder in 2012.
This pistol called the Liberator, which consists of 16 parts, including grip, trigger, frame and barrel, including 15 are using Stratasys 3D printer to print from the use of plastic, only some parts are made of non-functional metal, making this pistol can be detected, and therefore in line with "undetectable firearms Act" (undetectable firearms Act) requirements.
Liberator of CAD production of documents subsequently leaked on the network, and soon accumulated downloaded more than 100,000 times.
2.Liberator tests
May 2013, the world's first 3D print pistol Liberator in Texas Central Austin a range completed the first test. But Wilson this exciting "first" does not seem satisfied, because after only a few shots, Liberator protection guide pin at the barrel will be shattered, but fortunately the gun itself is no serious damage or cause accidents.
3. The world's first 3D printed rifle
Gun enthusiasts "HaveBlue" announced its 3D printing rifle (A.22 rifle) specification documents in his blog, has become the first successful 3D print out the rifle and gun test of the success stories.
HaveBlue uses 3D printers by Stratasys, CMMG .22 installation package, print out a a. 22 rifle (caliber 5.58mm), with the AK-47, are firing operation by gas firing, gunpowder airway gas through the barrel above the machine directly into the box, but there is a "gas button" on the barrel, when pressed, will air throughout the barrel.
4. 3D printing rifle upgrade
Matthew D print on the rifle which has been improved, its strength has been enhanced, projectiles amounted to 14 hair.
This .22 caliber rifle called "The Grizzly 2.0" is to use ABS material and plastic, the test-firing experiments, this rifle shot 14 times after cracks appeared, although compared to modern firearms, the 14 times the number of shots still seems too fragile, but this is a rifle with ABS plastic material and made it can be considered a good result.
5. pure metal 3D printing gun
Many gun 3D printing thanks BS and plastics manufacturing, in terms of durability compared to genuine nature can not drink. However, recently, known as the world leader in 3D printing technology of Solid Concepts companies said they use 3D printing technology successfully printed pure metal gun. This pistol super classic 1911 pistol as the prototype, uses a "laser printing technology", after successive rounds fired 50 guns still able to maintain intact.
Solid Concepts company says this technology to 3D printing has brought a qualitative leap, 3D printing will also apply to those from high-strength products and industries.
