Laser metal deposition (LMD) is an additive manufacturing process in which a feedstock material (typically a powder) is melted with a laser and then deposited onto a substrate. [1] A variety of pure metals and alloys can be used as the feedstock, as well as composite materials such as metal matrix composites .
In powder-fed directed-energy deposition, a high-power laser is used to melt metal powder supplied to the focus of the laser beam. The laser beam typically travels through the center of the deposition head and is focused to a small spot by one or more lenses.
DragonFire is a British laser directed-energy weapon (LDEW). It was first unveiled to the public as a technology demonstrator in 2017 at the Defence and Security Equipment International (DSEI) conference in London and is being developed by UK DragonFire, a collaboration consisting of MBDA UK, Leonardo UK, QinetiQ and the Defence Science and Technology Laboratory (dstl).

Britain this week showed off a new laser weapon that the military says could deliver lethal missile or aircraft defense at around $13 a shot, potentially saving tens of millions of dollars over ...
The laser beam is directed in the X and Y directions with two high frequency scanning mirrors and remains in focus along the layer utilising an F-Theta lens arrangement. The laser energy is intense and focused enough to permit full melting (fusion) of the particles to form a solid structure.
Once the stuff of science fiction, the prospect of advanced energy weapons like lasers being used in conventional military operations is fast becoming a reality.Nations around the world—with the ...
In powder-fed directed-energy deposition, a high-power laser is used to melt metal powder supplied to the focus of the laser beam. The powder-fed directed energy process is similar to selective laser sintering, but the metal powder is applied only where material is being added to the part at that moment. [136] [137]
A plume ejected from a SrRuO 3 target during pulsed laser deposition. One possible configuration of a PLD deposition chamber. Pulsed laser deposition (PLD) is a physical vapor deposition (PVD) technique where a high-power pulsed laser beam is focused inside a vacuum chamber to strike a target of the material that is to be deposited.
