RAPID PROTOTYPING

6.5 DIRECT METAL LASER SINTERINGDMLSDMLS technology was developed jointly by Rapid Prototyping Innnovations(RPI) and EOS Gmbh in 1994. It was the first commercial RP-method to producemetal parts in a single process. Metal powder (20 µm diameter) without binder iscompletely melted by scanning of a high power laser beam. The density of aproduced part is about 98 %. SLS has about 70 %. One advantage of DMLScompared to SLS is the small size of particles which enables very detailed parts.Abbreviation:Material type:Materials:Min layer thickness:Surface finish:Build speed:Applications:DMLSPowder (Metal)Ferrous metals such as Steel alloys, Stainless steel, Tool steel;Aluminium, Bronze, Cobalt-chrome, Titanium, Ceramics..0,02 mmAverageFastForm/fit testing, Functional testing, Rapid tooling, High heatapplications, Medical implants, Aerospace parts..15/02/2010 S.AARNIO
