Abstract: A printer and methods for additive manufacturing a build piece may include a camera and an optical spectrometer obtaining spectral information and optical information from a region of melted material to determine a defect condition based on an evaluation of processed spectral or optical information. A processor or a computer may process the obtained and optical information and determine a defect condition during the additively manufacturing process. The obtained spectral and optical information may be of the region of the melted material, a melt pool and a mushy zone. The printer and method may include a controller configured to modify a process parameter to shape the weld pool to obtain a desired effective absorptivity of a portion of the weld pool, e.g., to increase the effective absorptivity relative to an absorptivity of a surface of the powder or material deposited by the depositor and to maintain an acceptable temperature of the weld pool during the additively manufacturing process.
