EOS, Krailling, Germany, has launched the EOSINT M 280, an improved version of its own additive manufacturing systems for metals. The new system EOSINT M 280 is available with either a 200 W fiber laser, currently in the EOSINT M 270, or a 400 W fiber laser option. This higher power laser can melt more metal powder per second, thus achieving shorter build times and higher system productivity.
Especially for heavy use in a manufacturing environment, the newest system enables reduced costs-per-part, thereby increasing the competitiveness of laser sintering compared to other technologies and opening up new viable application areas.
Another improvement of the EOSINT M 280 compared to its predecessor is the increase of the maximum building height up to 325 mm. This enables taller parts to be placed in the process chamber, again expanding the application areas. This is particularly interesting for hybrid part building. In the hybrid process, complex parts are produced by building additional material on top of a prefabricated part.
Based on extensive process investigations and supported by fluid dynamics simulations, EOS has optimized the gas management system of the EOSINT M 280.
The EOSINT M 280 also builds on the Part Property Management concept, which enables standardization and comparability of building processes, based on the so-called Part Property Profiles (PPP). By ensuring a consistent quality assurance along the entire process chain, EOS enables machine users to reliably produce parts based on defined material and part properties.
The EOSINT M 280 supports all the materials of its predecessor, with the same or with optimized parameter sets. Currently, EOS offers 10 series materials, including the most recent EOS NickelAlloy IN625. For the 400 W option, new parameter sets with corresponding Part Property Profiles will be introduced. Customers can either use the pre-qualified EOS parameter sets or develop and modify their own.
“The EOSINT M 280 adopts all features and advantages of the well-established EOSINT M 270 system, and makes it even more attractive for a wide range of demanding applications including tooling and series production," said Peter Klink, EVP, Global Sales at EOS.
