Abstract (en)

[origin: WO2021038170A1] Equipment (10) comprising a laser head (18) intended to emit a laser beam (L) defining a longitudinal axis (X), a first, a second and a third container (12, 14, 16) respectively aligned in a first transverse plane substantially perpendicular to the longitudinal axis (X), the three containers each comprising a movable plate (24, 26, 28) that can move along the longitudinal axis (X), each plate being intended to receive a thickness of powder of which the free ends define three powder beds aligned in a second transverse plane, the equipment additionally comprising a movable scraper (20) intended to move in a third plane transverse with respect to the surface of the containers so as to be in contact with each of the powder beds, characterized in that it comprises a first and a second movable shield (30, 32) that are intended to move in the same third transverse plane as the movable scraper.
