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]
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.
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 .
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]
Direct metal laser sintering, or DMLS, uses a laser to sinter powdered metal into a solid object in gradual layers built upon each other. Cooling channels can be printed to any shape in this process, which lessens time and waste and improves quality. [2] Selective laser melting, or SLM, completely melts the powder to form a homogeneous part ...
