Grizzly (.22-caliber Rifle)
The Grizzly and the Grizzly 2.0 is a 3D printed .22-caliber rifle created around August 2013. It was created using a Stratasys Dimension 1200es printer. It was created by a Canadian only known by the pseudonym "Matthew" and told The Verge that he is in his late 20s, and his main job is making tools for the construction industry.First 3-D printed rifle fires bullet, then breaks NBC News, July 26, 2013.

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 sold i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberator (gun)
The Liberator is a 3D-printable single shot handgun, the first such printable firearm design made widely available online. The open source firm Defense Distributed designed the gun and released the plans on the Internet on May 6, 2013. The plans were downloaded over 100,000 times in the two days before the United States Department of State demanded that Defense Distributed retract the plans. The plans for the gun remain hosted across the Internet and are available at file sharing websites like The Pirate Bay and GitHub. On July 19, 2018 the United States Department of Justice reached a settlement with Defense Distributed, allowing the sale of plans for 3D-printed firearms online, beginning August 1, 2018. On July 31, 2018 President of the United States Donald Trump posted on Twitter about the decision to allow the online publication of the Liberator's files: “I am looking into 3-D Plastic Guns being sold to the public. Already spoke to NRA, doesn’t seem to make much sens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABS Plastic
Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)''x''·(C4H6)''y''·(C3H3N)''z'' is a common thermoplastic polymer. Its glass transition temperature is approximately . ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene crisscrossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The acrylonitrile also contributes chemical resistance, fatigue resistance, hardness, and rigidity, while increasing the heat deflection temperature. The styrene gives the plastic a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease. The polybutadiene, ...

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.
