Selective laser melting (SLM) is one of many proprietary names [1] for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF).
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.
That aspect allows classification of EBM with selective laser melting (SLM), where competing technologies like SLS and DMLS require thermal treatment after fabrication. Compared to SLM and DMLS, EBM has a generally superior build rate because of its higher energy density and scanning method. [citation needed] Electron-beam melting hardware
Direct metal laser sintering (DMLS) is one type of additive manufacturing process that allows layer by layer printing of metal parts having complex geometries directly from 3D CAD data. It uses a high-energy laser to sinter powdered metal under computer control, binding the material together to create a solid structure.
Based on the foregoing merge discussion, I propose to merge Direct metal laser sintering, Selective laser sintering and Selective laser melting into a new article Laser sintering, since all 3 are just a subset of each other. There already is a lot of overlap and 1 article can simply and clearly explain the small differences between them.
I agree, in my experience, SLM and DMLS are pretty much the same thing, as indicated by this chart which lists "DMLS/SLM" as one item. —Ben FrantzDale 19:04, 6 June 2017 (UTC) I don't why SLM should be merged into DMLS, I really think DMLS should be merged into SLM. Because SLM is the common name, and DMLS is a brand-specific name, like "DMLM ...
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]
