Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...
The gun is made up of 34 3D-printed components. [14] Notable as the first fully metal 3D-printed firearm. Zig Zag revolver [2] [15] 2014, May [15] Primarily printed firearm: Revolver [2] FDM [2] Yoshitomo Imura [15].38 Caliber Named after the German Mauser Zig-Zag revolver. Holds six cartridges and can fire .38 caliber bullets. [12] Imura ...
In the United States, the Hill Air Force base is using 3D printed parts in repair of fighter jets. [76] Higher education has proven to be a major buyer of desktop and professional 3D printers. [77] Significant desktop 3D printer purchases by both K-12 and universities helped sustain a desktop 3D printer market that had problems in 2015–2016. [78]
A photomask (also simply called a mask) is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or "chips") to produce a pattern on a thin wafer of material (usually silicon ).
Mask data preparation (MDP), also known as layout post processing, is the procedure of translating a file containing the intended set of polygons from an integrated circuit layout into set of instructions that a photomask writer can use to generate a physical mask. Typically, amendments and additions to the chip layout are performed in order to ...
Giselle Smith and Semaj Morris, 17, were both killed on Wednesday, Dec. 11, with Smith's sister Paris Kiper in critical condition
The pattern and sand are then inverted so the excess sand drops free of the pattern, leaving just the "shell". Depending on the time and temperature of the pattern the thickness of the shell is 10 to 20 mm (0.4 to 0.8 in). The pattern and shell together are placed in an oven to finish curing the sand.
