Easier to print, stiffer, and more brittle than other plastics. PLA+ is a term for any blend that enhances some characteristic. PETG Polyethylene terephthalate (glycol-modified), a plastic made by changing the chemicals used to synthesize the more common PET. Easier to print than ABS, and moderately better heat resistance than PLA.
The design of the Urutau is inspired by previously published 3D-printable firearm designs, the Shuty AP-9 pistol by Derwood, the FGC-9 by JStark1809, and the Partisan 9 by ImmortalRevolt [6] [7] [8] [9].While most of the underlying mechanics of The Urutau are comparable to the FGC-9, all parts were significantly redesigned. Compared to these ...
Piece of a 3D-printed Defense Distributed AR-57. A 3D-printed firearm is a firearm that is partially or primarily produced with a 3D printer.While plastic printed firearms are associated with improvised firearms, or the politics of gun control, digitally-produced metal firearms are more associated with commercial manufacturing or experiments in traditional firearms design.
The Liberator is a 3D-printable single-shot handgun, the first such printable firearm design made widely available online. [2] [3] [4] The open source firm Defense Distributed designed the gun and released the plans on the Internet on May 6, 2013.
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

The crossbow as a weapon had been around long before Leonardo's designs. However, his designs made the weapon more advanced and why Leonardo's crossbows stands out. If a crossbow is designed with a narrower shaft and a tapered bolt, which adjusts the nocking of arrows, it greatly improves the airflow of the bow and the drag on arrows.
