Lower Receiver
In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving") components such as the barrel, stock, trigger mechanism and iron/ optical sights. Some firearm designs, such as the AR-15 platform, feature receivers that have 2 separate sub-assemblies called the upper receiver which houses the barrel/trunnion, bolt components etc and the lower receiver (Trigger Mechanism Housing in some cases) that holds the fire control group, pistol grip, selector, stock etc. The receiver is often made of forged, machined, or stamped steel or aluminium. Apart from these traditional materials, modern techniques have introduced polymer and sintered metal powder receivers to the market. Mounting A barrel may typically be affixed to a firearm receiver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Defense Distributed
Defense Distributed is an online, open-source hardware and software organization that develops digital schematics of firearms in CAD files, or "wiki weapons", that may be downloaded from the Internet and used in 3D printing or CNC, CNC milling applications. Among the organization's goals is to develop and freely publish firearms-related design schematics that can be downloaded and reproduced by anyone with a 3D printing, 3D printer or Milling (machining), milling machine, facilitating the popular production of ghost gun, homemade firearms. The company is best known for developing and releasing the files for the Liberator (gun), Liberator, the world's first completely 3D printed gun.

Stratasys
Stratasys, Ltd. is an American-Israeli manufacturer of 3D printers, software, and materials for polymer additive manufacturing as well as 3D-printed parts on-demand. The company is incorporated in Israel. Engineers use Stratasys systems to model complex geometries in a wide range of polymer materials, including: ABS, polyphenylsulfone (PPSF), polycarbonate (PC) and polyetherimide and Nylon 12. Stratasys manufactures in-office prototyping and direct digital manufacturing systems for automotive, aerospace, industrial, recreational, electronic, medical and consumer product OEMs. History Stratasys was founded in 1989, by S. Scott Crump and his wife Lisa Crump in Eden Prairie, Minnesota. The idea for the technology came to Crump in 1988 when he decided to make a toy frog for his young daughter using a glue gun loaded with a mixture of polyethylene and candle wax. He thought of creating the shape layer by layer and of a way to automate the process. In April 1992, Stratasys so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fused Deposition Modeling
Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or ''filament freeform fabrication'', is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer. The speed of the extruder head may also be controlled to stop and start deposition and form an interrupted plane without stringing or dribbling between sections. "Fused filament fabrication" was coined by the members of the RepRap project to give an acronym (FFF) that would be legally unconstrained in use. Fused filament printing has in the 2010s-2020s been the most popular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3D Printed Firearms
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.New Zealand leads the way in Titanium Additive Manufacturing Metal Additive Manufacturing, May 12, 2014. Although it is possible to create fully-printed plastic firearms and silencers, these tend to have short working lives. 3D-printed gun culture is built around the printing of |
Firearm Components
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see #Legal_definitions, legal definitions). The first firearms originated in 10th-century History of science and technology in China, China, when bamboo tubes containing gunpowder and Lead shot, pellet projectiles were mounted on Spear, spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have riflin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ArmaLite AR-10 Derivatives
ArmaLite, or Armalite, is an American small arms engineering company, formed in the early 1950s in Hollywood, California. Many of its products, as conceived by chief designer Eugene Stoner, relied on unique foam-filled fiberglass butt/stock furniture and a composite barrel using a steel liner inside an aluminum sleeve, including the iconic AR-15/ M16 family. While the original ArmaLite ceased doing business in the 1980s, the brand was revived in 1996, by Mark Westrom. Originating as the light firearms division of Fairchild Engine and Airplane Corporation, ArmaLite was formally incorporated in 1954. Stoner's first design, the AR-1 Parasniper (dating from 1952), was relatively unsuccessful. However, in 1956, when ArmaLite competed in a contest for an aircrew survival rifle, its AR-5 and AR-7 designs were put into production and adopted by elements of the US military. In 1957, ArmaLite also competed for the contract for a new main US combat rifle, in the NATO standard 7.62 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
