The EOSINT M 280 machine, which was introduced at the EuroMold 2010 show, is an improvement version of the company’s current additive manufacturing systems for metal components. "The machine sets new standards in terms of part quality and reproducibility, while at the same time improving cost-effectiveness and user-friendliness,” claims Peter Klink, executive vice president global sales at EOS. EOSINT M 280 is now available with either the same 200 Watt fibre laser as fitted to the EOSINT M 270, or a new 400 Watt laser for increased build speed and productivity. This higher power laser can melt more metal powder per second, achieving shorter build times and higher system productivity. This in turn can help reduce cost-per-part, raising the competitiveness of laser-sintering compared to other technologies and opening up additional application areas. The laser sintering machine also has a maximum build height to 325 mm, compared with 215 mm for the M 270. Taller parts may therefore be produced in the process chamber, expanding the range of applications, including for hybrid part building. In this hybrid process, complex parts are produced by building additional material on top of a prefabricated part. EOSINT M 280 also has improved gas management, featuring a high velocity, laminar flow of protective gas across the entire build area and a high capacity recirculating filter system.  

  • EOS has also developed new plastic and material material to be launched at the show. These include EOS NickelAlloy IN625 and, PrimePart FR (PA 2241 FR) and PrimePart ST (PEBA 2301) for plastic parts. EOS NickelAlloy IN625 has high tensile strength, improved processability and uniform corrosion resistance, making it suitable for use in aerospace, chemical, motorsport and marine applications. It has been successfully tested in the building of complex aerospace parts for high temperature and high strength applications.
