A few days ago, the Liberator test, the first 3D printer gun, was unsuccessful. Weapons spread out after the first shot. After modifying several components, successive tests began, with more success.
The new version of Liberator has undergone further tests. This time it was possible to fire a full magazine and without destroying the gun. The interesting thing is that Lulz Liberator, was created on even cheaper 3D printer model than its original version. It was made for the $ 1725 Luzbot A0-101 model for the consumer market, resulting in a total cost of $ 25.
What different Lulz Liberator from previous model apart from other printer? Also material. In this case, plastic Polylac PA-747 ABS was used, which is more durable than the more expensive plastic ABS used in the previous weapon.
Both models are not just plastic because they have some metal in them, otherwise they would not be able to fire a bullet. The metal is a trigger spindle, and additionally a piece of metal is installed so that the weapon can be detected by the detectors.
Although Lulz Liberator seems to be quite functional, it's still a long way to commercial plastic weapons production.
