Fine-focus laser speeds up precision sintering

Article-Fine-focus laser speeds up precision sintering

EOS says the newest model in its Eosint M Series for laser sintering powdered metal uses a new generation of laser to boost speed and improve part detail resolution. The M Series machines sinter powdered metal to make tooling or short-series production metal parts directly.

The solid-state fiber laser technology in the new Eosint M 270 generates a very narrowly focused beam. The beam, being both more intense and higher resolution, can increase productivity through faster build speed while simultaneously supporting an increased level of detail in the part. Besides being used to make laser sintered tools for molding plastics or casting metals (DirectTool), M Series machines are increasingly used for direct production of metal parts needed in small quantities. For example, EOS makes the closure for the processing chamber of the Eosint M 270 by laser sintering its own Alumide and DirectSteel. EOS also recently introduced a new grade of DirectSteel called H20 in response to market needs for still-harder materials. The H20 grade, which has been tested by EOS users making mold inserts, offers hardness up to 42 Rockwell C and will be on the market early this year. DirectSteel has already been used to make inserts for a four-cavity mold that has produced more than 3 million thin-wall parts in a high-speed molding operation.
