How to fix inert gas flow faults on an EOS M 290 / M 400 metal additive manufacturing system
Inert gas flow faults interrupt the build to protect part quality and prevent fire. Check the gas supply pressure, verify the flow sensor, and inspect the filter cartridge before resuming.

How to diagnose laser power drift on an EOS M 290 / M 400 metal additive manufacturing system
Laser power drift causes inconsistent melt pool size and part density. Perform a laser power measurement with the EOS power meter and recalibrate if output deviates from the nominal parameter by more than 3 percent.

How to fix recoater blade streaking on an EOS M 290 / M 400 metal additive manufacturing system
Recoater streaks create density voids in the build layer. Inspect the recoater blade for chips or debris, clean the blade edge, and check for spatters in the build plane before resuming.
