Charon (gun)
The DEFCAD Charon is an open source 3D-printable AR-15 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, a ... project that was partially inspired by the Fabrique Nationale P90. It began as a design exercise by a DEFCAD user to explore FDM additive manufacturing technology as a means of integrating the P90's ergonomics into a stock for the AR-15, resulting in the WarFairy P-15 stock set. The additive manufacturing process permits curvilinear designs that are too expensive or impossible to do by subtractive methods.Johnson,Steve"WarFairy’s Latest Additions To The Charon Line Of Printable AR-15s′" 30 May 2013.Archive From the P-15, it was integrated with the DefDist V5 lower receiver, resulting in the WarFairy Charon V0.1.

Charon Line Of 3D Printable AR-15 Lower Receivers By Shanrilivan
In Greek mythology, Charon or Kharon ( ; ) is a psychopomp, the ferryman of the Greek underworld. He carries the souls of those who have been given funeral rites across the rivers Acheron and Styx, which separate the worlds of the living and the dead. Archaeology confirms that, in some burials, low-value coins known generically as Charon's obols were placed in, on, or near the mouth of the deceased, or next to the cremation urn containing their ashes. This has been taken to confirm that at least some aspects of Charon's mytheme are reflected in some Greek and Roman funeral practices, or else the coins function as a viaticum for the soul's journey. In Virgil's epic poem, ''Aeneid'', the dead who could not pay the fee, and those who had received no funeral rites, had to wander the near shores of the Styx for one hundred years before they were allowed to cross the river. Charon also ferried the living mortals Heracles and Aeneas to the underworld and back again. Name origins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DEFCAD
DEFCAD, Inc. is an American startup that has created a search engine and web portal for designers and hobbyists to find and develop 3D printing, 3D printable and other Computer-aided design, CAD models online. History Founding When Makerbot, Makerbot Industries removed 3D printed firearms, firearms-related 3D Printable files at the public repository Thingiverse in December 2012, open-source software entrepreneurs Cody Wilson and Ashley Tyson launched DEFCAD as a companion site to publicly host the removed files. Public and community submissions to DEFCAD rose quickly, and by March 2013, at the SXSW Interactive festival, DEFCAD announced a repurposed and expanded site that would serve as a 3D search engine and development publication platform. DEFCAD has been called "The Pirate Bay of 3D Printing" and "the anti-Makerbot". Community DEFCAD began as a repository where users could upload and download CAD models, but quickly became a community with the addition of an Internet Rela ...

3D Printing
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology; in this context, the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise infeasi ...

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] |
Fabrique Nationale P90
The FN P90 is a personal defense weapon chambered for the FN 5.7×28mm, 5.7×28mm Cartridge (firearms), cartridge, also classified as a submachine gun, designed and manufactured by FN Herstal in Belgium. Created in response to NATO requests for a replacement for 9×19mm Parabellum firearms, the P90 was designed as a compact but powerful firearm for vehicle crews, operators of crew-served weapons, support personnel, special forces, and counter-terrorist groups. Designed in conjunction with the FN Five-seven pistol and FN 5.7×28mm, FN 5.7×28mm NATO ammunition, development of the weapon began in 1986, and production commenced in 1990, when it was known as the ''Project 9.0'' (from which the "90" in its name is derived), whereupon the 5.7×28mm ammunition was redesigned and shortened. A modified version of the P90 with a Magazine (firearms), magazine adapted to use the new ammunition was introduced in 1993, and the Five-seven pistol was subsequently introduced as a companion weapo ...

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] |
