The table below lists noteworthy 3D printed weapons (mainly 3D printed firearms) and parts of weapons as well as items with a defense-related background. It includes 3D printed weapons and parts created using plastic producing printers as well as metal producing printers. The Liberator .380 was the first 3D printed plastic gun made widely ...
3D printed firearm. A 3D printed firearm is a firearm that is partially or primarily produced with a 3D printer. While plastic printed firearms are associated with improvised firearms, or the politics of gun control, digitally-produced metal firearms are more associated with commercial manufacturing or experiments in traditional firearms design.
Laser printing (toner printing) mainly used in offices and for transactional printing (bills, bank documents). Laser printing is commonly used by direct mail companies to create variable data letters or coupons. Pad printing, popular for its ability to print on complex three-dimensional surfaces.
Like other SSRIs, sertraline can cause a range of possible side effects that typically occur during the first few weeks of treatment, including: Nausea. Fatigue and tiredness. Intimacy problems ...
Left: Halftone dots. Right: Example of how the human eye would see the dots from a sufficient distance. Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. [1] ". Halftone" can also be used to refer specifically to ...
List of refractive indices. Refraction at interface. Many materials have a well-characterized refractive index, but these indices often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers .
Upon heating, it softens at 50 °C and converts to gray selenium at 180 °C; the transformation temperature is reduced by presence of halogens and amines. [9] The red α, β, and γ forms are produced from solutions of black selenium by varying the evaporation rate of the solvent (usually CS 2 ).
Ursus lotor Linnaeus, 1758. The raccoon ( / rəˈkuːn / or US: / ræˈkuːn / ⓘ, Procyon lotor ), also spelled racoon [3] and sometimes called the common raccoon or northern raccoon to distinguish it from the other species, is a mammal native to North America. It is the largest of the procyonid family, having a body length of 40 to 70 cm (16 ...
