METHODS FOR LASER CALIBRATION IN ADDITIVE MANUFACTURING SYSTEMS, AND SYSTEMS CONFIGURED FOR SAME

A method of calibrating a laser of an additive manufacturing system involves processing a test pattern with the laser while varying one or more of laser power and/or scan speed. Thermal energy emitted from the resulting meltpool is measured while processing the test pattern. The power of the laser is calculated using a relationship between volumetric energy density and the thermal emissions, and the laser power is adjusted based on the calculated laser power. An additive manufacturing system for performing such a method may include a laser, a thermal sensor configured to measure meltpool thermal emissions, a processor configured to calculate a laser power based on the measured meltpool thermal emissions of the test pattern, and a controller configured to adjust the laser power based on the calculated laser power.

ADDITIVE MANUFACTURING METHOD AND DEVICE

The invention relates to an additive manufacturing method in which a component (10, 42, 43, 44, 45) is produced in layers using an energy beam (8, 41, 58) which solidifies a starting material (4) and is irradiated by energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) while the starting material (4) is held by a base surface (3, 15, 30, 36, 52) arranged on a base element (2, 16, 29, 35, 51). While the starting material (4) is being irradiated with the energy beam (8, 41, 58), the base element (2, 16, 29, 35, 51) is moved by a rotational component which has a base element rotational axis, wherein the starting material (4) is held on the base surface (3, 15, 30, 36, 52) by a centrifugal acceleration generated by the rotational component. The invention is characterized in that a rotational movement is produced for at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61). Analogously, at least one energy beam rotational axis (46) is proposed for rotating at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) in an additive manufacturing device in which the starting material (4) is held on a base surface (3, 15, 30, 36, 52) by a centrifugal acceleration.
