Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts.The raw material (metal powder or wire) is placed under a vacuum and fused together from heating by an electron beam.
[2] 3D-printed gun culture is built around the printing of open-source firearm frames and receivers, the use of standard, metal commercial components (like an action and barrel), and other parts that can be made or purchased in a parts kit. [3] [a] While 3D-printed parts are made in the development and production of conventional firearms, they ...
The gun is made up of 34 3D-printed components. [17] Notable as the first fully metal 3D-printed firearm. Zig Zag revolver [5] [18] 2014, May [18] Primarily printed firearm: Revolver [5] FDM [5] Yoshitomo Imura [18].38 Caliber Named after the German Mauser Zig-Zag revolver. Holds six cartridges and can fire .38 caliber bullets. [15] Imura ...
At the 2017 Consumer Electronics Show, Markforged unveiled the Metal X, which is a 3D printer capable of 3D printing metal parts at a low cost, under $100k. [8] The process has been referred to as ADAM (Atomic Diffusion Additive Manufacturing) technology and it has an in-process laser inspection for dimensional accuracy. [5]
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.
This technology was first developed at the Massachusetts Institute of Technology and patented in 1993. In 1996, the ExOne Company was granted an exclusive field-of-use patent for the technology, [2] while Z Corporation, which was later acquired by 3D Systems, [3] obtained a non-exclusive patent for use of the technology for metal casting purposes. [4]
The process can not only fully build new metal parts but can also add material to existing parts for example for coatings, repair, and hybrid manufacturing applications. LENS (Laser Engineered Net Shaping), is one example of the Powder Fed - Directed Energy Deposition process for 3D printing or restoring metal parts. [65] [66]
Printing: The process begins with printing the part using a filament containing metal powder bound in plastic. This filament, similar to that used in conventional FFF printers, is infused with metal. The printer deposits the metal-infused filament layer by layer, building up the shape of the part. These printed parts are referred to as "green ...
