Direct metal laser sintering (DMLS)<\/a> belongs to the powder bed fusion (PBF) category of 3D printing and is similar to the SLS<\/a> technology. In DMLS, however, metal powders are used instead of plastic powders to create metal parts that can be used both for functional prototypes and production parts. <\/p>\n\n\n\n

Direct metal laser sintering technology is similar to Selective laser melting (SLM) technology, but the difference between both processes is the temperature used for metal powder fusion. SLM, as the name suggests, heats the metal powder until it fully melts into a liquid. DMLS does not melt the metal powder but sinters heat particles enough so that their surfaces weld together. Anyway, both terms (SLM and DMLS) are often used interchangeably in the 3D printing industry.<\/p>\n\n\n\n
