US 2021/0331245 A1 · METHOD OF MONITORING AN ADDITIVE MANUFACTURING PROCESS, ADDITIVE MANUFACTURING METHOD, APPARATUS FOR MONITORING AN ADDITIVE MANUFACTURING PROCESS AND ADDITIVE MANUFACTURING APPARATUS

Abstract

A method of monitoring an additive manufacturing process according to at least one embodiment of the present disclosure includes the steps of acquiring information on a temperature of a region upstream of a melt pool in a scanning direction of an energy beam, the melt pool being formed by irradiating a raw material with the energy beam, acquiring a parameter indicating a cooling rate of the region based on the information on the temperature, and determining a formation status based on the parameter.
