Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.
Direct metal laser sintering, a process that fuses metal powder by sintering. SLM Selective laser melting, a process that fuses metal powder by melting. ABS Acrylonitrile butadiene styrene, a common thermoplastic with relatively high heat resistance. ABSplus is a stronger, proprietary blend of ABS by Stratasys. PLA Polylactic acid, a bio ...
A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing.
Silent Hunter (laser weapon) Chinese fiber-optic laser air-defense system. Described as being able to penetrate five 2 millimeter steel plates at a range of 800 meters and 5 millimeters of steel at 1,000 meters. Status unknown [61] [62] [63] Russian Sokol Eshelon: Experimental airborne laser weapon developed by Russia, mounted on the Beriev A-60.
In the mid-2010s, the next generation of laser pistols appeared, which were specially produced for modern pentathlon and laser run. [10] This resulted in different approaches to construction: On the one hand, there are still models with the structure of a match air pistol: a very thin barrel and a more voluminous container underneath which ...
An electrolaser is a type of electroshock weapon that is also a directed-energy weapon.It uses lasers to form an electrically conductive laser-induced plasma channel (LIPC). A fraction of a second later, a powerful electric current is sent down this plasma channel and delivered to the target, thus functioning overall as a large-scale, high energy, long-distance version of the Taser ...

European officials have noted that producing a 3D-printed gun would be illegal under their gun control laws, [26] and that criminals have access to other sources of weapons, but noted that as the technology improved the risks of an effect would increase. [27] [28] Downloads of the plans from the UK, Germany, Spain, and Brazil were heavy. [29] [30]
