3D Print
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 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, whereby 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 impossible to construct ...

Fabrique Nationale P90
The FN P90 is a compact 5.7×28mm personal defense weapon designed and manufactured by FN Herstal in Belgium. It can also be considered a submachine gun. 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 5.7x28mm NATO ammunition, development of the weapon began in 1986, and production commenced in 1990 (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 adapted to use the new ammunition was introduced in 1993, and the Five-seven pistol was subsequently introduced as a companion weapon using the same 5.7×28mm ammunition. Featuring a compact bullpup design with an integrated reflex sight and fully ambidextro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stock (firearms)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LulzBot
Aleph Objects, Inc. was a small manufacturing company based in Loveland, Colorado. Their business model focused around the development of Open-source hardware for 3D printing with full support for Free and open-source software. LulzBot The company is most well known for its LulzBot 3D printer product line, which although using some extruded aluminum railing and other mass-production components still remains true to RepRap principles by having many components 3D printable. Due to its fully open source hardware and open source software design, the LulzBot Taz 6 has received "Respects Your Freedom" certification from the Free Software Foundation. In addition, the Lulzbot printers are often used in open-source tool chains on open source projects.

Fused Deposition Modeling
Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or called ''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 its use. Fused filament printing is now the most popular process ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Receiver
In firearms terminology, 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. The receiver is often made of forged, machined, or stamped steel or aluminium; in addition to these traditional materials, modern science and engineering have introduced polymers and sintered metal powders to receiver construction. Mounting A barrel can be fixed to the receiver using barrel and receiver action threads or similar methods. In US law For the purposes of United States law, the receiver or frame is legally the firearm, and as such it is the controlled part. The definition of which assembly is the legal receiver varies from firearm to firearm, under US law. Generally, the law require ...

Charon (gun)
The DEFCAD Charon is an open source 3D printing, 3D-printable AR-15 lower receiver project that was partially inspired by the Fabrique Nationale P90. It began as a design exercise by a DEFCAD user to explore Fused deposition modeling, 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. From the P-15, it was integrated with the DefDist V5 lower receiver, resulting in the WarFairy Charon V0.1. Further advantage was taken of the nature of Fused deposition modeling, FDM polymer printing to make it possible for printers with small work envelopes to produce large items, i.e., the Charon was designed to be printed in sections and then assembled with solvent cemen ...

AR-15
An AR-15-style rifle is any lightweight semi-automatic rifle based on the Colt AR-15 design. The original ArmaLite AR-15 is a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959. After most of Colt's patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. While the patents are expired, Colt retained the trademark of the AR-15 and is the sole manufacturer able to label their firearms as ''AR-15''. The "AR" in Colt AR-15 stands for "ArmaLite Rifle", not " assault rifle". The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports F ... [...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 printable and other CAD models online. History Founding When Makerbot Industries removed firearms-related 3D Printable files at the public repository Thingiverse in December 2012, open source software entrepreneurs launched DEFCAD as a companion site to publicly host the removed files. Public and community submissions to DEFCAD rose quickly, and in March 2013, at the SXSW Interactive festival, DEFCAD was announced as a repurposed and expanded site that would serve as a 3D search engine and development hub. 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 IRC channel and public forums. The site has had over 2,500 community users and offered access to over 100,000 models i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3D Printed Firearms
A 3D printed firearm is a firearm that is primarily produced with a 3D printer. They can be classified by the type of 3D printers used: plastic (desktop fused filament fabrication), metal (industrial selective laser melting), or both. While plastic ones are usually used as improvised firearms that evade gun control, 3D-printed metal guns are more commonly thought as a way for legitimate gun manufacturers to exceed traditional design limitations.New Zealand leads the way in Titanium Additive Manufacturing Metal Additive Manufacturing, May 12, 2014.
