Claim 0:
1. A method for thermal monitoring for a metal additive manufacturing system, the method comprising:
determining an emissivity value based, at least in part, on an arithmetic product of a predetermined roughness value and a predetermined slope-related value, wherein the predetermined roughness value and the predetermined slope-related value are predetermined based, at least in part, on measurements of a previously manufactured object;
sintering, by the metal additive manufacturing system, of a metal to form a top surface of an object to be manufactured;
detecting, using an infrared sensor, infrared radiation from at least a portion of the top surface of the object to be manufactured;
generating a temperature based, at least in part, on the detected infrared radiation and the emissivity value; and
applying the temperature to a temperature utilization component of the metal additive manufacturing system.
