Next-generation LPBF with six 400 W lasers (450×450×400 mm), or four 1 kW FLX variant. 50% faster, 30% cheaper than prior EOS systems.
Launching Q1 2026 (base model); Q3 2026 (FLX variant with 1 kW lasers). Succeeds the M 400 series.

Six independent laser beams work simultaneously, each melting a separate zone. This parallelism doubles the throughput compared to four-laser systems.
Integrated thermal sensors and active gas flow keep the build volume at optimal temperature, reducing warping and cracking.
Sensors detect defects in-process, reducing inspection time by up to 50% and lowering scrap rates.
