In the world of laser additive manufacturing, traditional defect detection methods such as thermal imaging and machine learning algorithms have fallen short. These methods often overlook or misinterpret defects, leaving room for subpar product quality. But why is this the case?

Thermal imaging, while useful in identifying temperature variations, fails to capture the intricate details of defects that may not necessarily affect the temperature. On the other hand, machine learning algorithms heavily rely on pre-trained models, which may not encompass the full range of potential defects.

It is clear that a new approach is needed to address these limitations and ensure the highest level of product quality in laser additive manufacturing.
