| Abstract Scope |
Part qualification in Laser Powder Bed Fusion (LPBF) additive manufacturing is a significant and complicated challenge, as it often requires destructive testing of high-value materials. This work presents a lightweight and non-invasive in-situ monitoring system that captures critical process data while maintaining a minimal number of sensors and a minimal amount of storge space required. As a start to this transferable open source in-situ monitoring framework, both infrared and visible-light cameras combined with thermocouples and photodiodes are integrated into an EOS M290 and recorded in a time-synchronized fashion using ROS2. OpenCV is utilized for edge detection and flagging of regions of interest within the part and helps reduce the size of each frame for efficient data handling. The proposed approach aims to identify process anomalies and provide a part-level thermal history to support user driven interpretation of part quality, without changing the LPBF system workflow. |
