Come and Take It: The Gun Printer's Guide to Thinking Free is an autobiographical book written by American gun rights activist, author and crypto-anarchist, Cody Wilson in 2016. The book describes Wilson's decisions behind wanting to create the world's first 3D printed gun , the Liberator , and the formation of his company Defense Distributed ...
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.
Often used in consumer-level printers when creators desire better heat resistance than PLA+ or need more flexibility. ECM Electrochemical machining, a process that uses electricity to chemically machine metal. Commonly used in 3D printed firearms to create DIY barrels with rifling, greatly increasing accuracy. FCG
Cults was founded in 2014 and is the first fully independent 3D printing marketplace. [1]In 2015, La Poste established a partnership with Cults and 3D Slash to develop impression3d.laposte.fr, a digital manufacturing service, allowing users to have objects printed and shipped to them on demand.
The market for 3D printers has grown tremendously over the past several years. According to Wohlers Report 2018, 3D printer Market reached 7.3 billions $ in 2017, with +21% growth over the previous year. [1] The market is mostly B2B right now, because 3D printing is still a complex process.
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
Both are complete systems for translating 3D computer models into G-code, the machine language that commands the printer. Later, other programs like Slic3r and Cura were created. Recently, the Franklin firmware was created to allow RepRap printers to be used for other purposes such as milling and fluid handling.
The process of transforming 3D printing filament into a 3D model The filament is fed into the FDM 3D printer. The thermoplastic is heated past its glass transition temperature inside the hotend. The filament is extruded and deposited by an extrusion head onto a build platform where it cools. The process is continuous, building up layers to ...
