Abstract
Apparatuses and methods are provided that provide adaptive multi-process additive manufacturing systems for monitoring, measuring, and controlling additive manufacturing processes. A first laser (e.g., a fiber laser) is used for melting and consolidating the powder, and a second laser is utilized for dual purpose: (a) for metrology to measure the surface roughness, dimensional accuracy, material properties, etc., and (b) based on the evaluated measurements to take corrective actions (laser ablation, etc.) to attain the desired surface finish and dimensional accuracy. Various elements provide defect detection, defect identification, and defect response actions which remove defect related material or address under print or missing material in a build object.
