Permanent Filtration and Closed-Loop Powder Circulation

EP-M400S uses a three-stage blow-back filtration system with a permanent filter element, reducing routine filter replacement around long production jobs. The machine supports one to four lasers with multiple power levels, top-fed powder dosing, and bidirectional recoating to shorten non-exposure time. Closed-loop powder circulation and the ability to refill powder without interrupting the print keep material handling inside a controlled inert workflow.
