Optical System for On-Line Monitoring and Temperature Control in Selective Laser Melting Technology

Abstract:

A monitoring system is developed to visualize and to control the process of Selective Laser Melting (SLM) of metallic powder. The system is integrated with industrial PHENIX PM-100 machine. Visualization is carried out using LED illumination and CCD-camera; a home developed pyrometer is applied for monitoring of thermal phenomena in the zone of laser impact. Deviation of temperature from its optimal value is chosen as a criterion for the express method of quality control.
