Selective laser melting (SLM) machines can operate with a work space up to 1 m (39.37 in) in X, Y and Z. [10] [11] Some of the materials being used in this process can include Ni based super alloys, copper, aluminum, stainless steel, tool steel, cobalt chrome, titanium and tungsten.
A variety of Selective Laser Melting machines with laser outputs from 100 to 2800 Watt are sold, the latter distributed on four lasers. According to manufacturer specifications, the top model is the currently (April 2014) highest-performing metal 3D printer on the market and cost approximately 1.5 million euros. [1]
As the laser source moves away, the melt pool follows, with the material at the previous location solidifying. This process is typically achieved using a laser cladding head, which integrates the powder nozzles and the laser optics into one assembly, with both focused at a single target location. The size and area of the melt pool and the ...
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...
An immense slab of "continuous melt" processed neodymium-doped laser glass for use on the National Ignition Facility. This is a list of laser types, their operational wavelengths, and their applications. Thousands of kinds of laser are known, but most of them are used only for specialized research.

Selective laser melting (SLM) does not use sintering for the fusion of powder granules but will completely melt the powder using a high-energy laser to create fully dense materials in a layer-wise method that has mechanical properties similar to those of conventional manufactured metals. [36] [37]
