Abstract：
Metal additive manufacturing technology had been widely used in aerospace, medical and other fields. However,it still faces many quality defects such as cracks, voids and warping. It is very necessary to carry out quality inspection on part of forming parts in the early stage, discover defects in forming process, and repair defects or abort machining process by feedback control adjustment parameters. Based on the three dimensional structure light measurement technology and some related key technologies, an online measurement system for monitoring the melting process of powder bed is developed.
