EOS Launches EOSINT M 280 Additive Manufacturing System

By DE Editors

EOS is showcasing its solution portfolio at this year’s EuroMold, including its new EOSINT M 280 additive manufacturing system for metals.

“This system sets new standards in terms of part quality and reproducibility, at the same time improving cost-effectiveness and user-friendliness,” says Peter Klink, executive vice president, Global Sales at EOS. “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.”

The EOSINT M 280 is available with either the same 200-watt fibre laser, which is used in the EOSINT M 270,  or a 400-watt fibre laser option. This higher-power laser can melt more metal powder per second, thus achieving shorter build times and higher system productivity. For example, an injection molding core is being displayed at EuroMold that was built in less than half the time compared to the EOSINT M 270.

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.

EOS has also optimized the gas management system of the EOSINT M 280. A high-velocity laminar flow of protective gas across the entire build area, combined with the high-capacity recirculating filter system, ensures even more uniform process conditions,  according to the company. It also supports processes both under nitrogen gas atmosphere, created by compressed air via an integrated nitrogen generator, as well as under argon gas. Moreover, further improvements in the gas management system enable a reduction of the gas consumption and a prolonged filter lifetime.

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-watt option new, faster 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 base module of the EOSTATE 1.2 software allows the machine status to be monitored. Additional EOSTATE modules, including Quality Assurance, Controlling and MPM (Machine Park Management), are also available. These allow a statistical overview of the built jobs and parts over freely selectable periods of time. Integrated Process Chain Management (IPCM) modules offer optimized powder and part handling.
