The OPM series is a fully automatic machine which performs high precision finish machining where a metal powder is spread uniformly (recoating process), the metal powder is scanned with a laser beam to solidify the melted powder, and a rotary tool is used to perform high-speed milling. The adoption of an Yb fiber laser with a maximum output of 500W for the laser oscillator which solidifies the melted metal powder, realized high-speed metal 3D printing.
