Metal printing is one of the rarest 3D printing technologies. The metal powder is bonded by laser sintering to form the object. This technology produces highly detailed objects directly into metal without the limitations of CNC tools, die casting or other traditional methods of metal production.
In Laser Metal Fusion technology, also known as selective laser melting, the laser heats the metal dust by melting it right on the site, according to CAD data, and attaches certain points to the bottom layer. This means that the powder is not just heated, but is actually melted in a homogeneous medium with the bottom layer. Which allows the use of pure metal powder materials, in addition to metal alloys.
