  text: Confidence in additive manufacturing technologies is directly related to the
    predictability of part properties, which is influenced by several factors. To
    gain confidence, online process monitoring with dedicated and reliable feedback
    is desirable for every process. In this project, a powder bed monitoring system
    was developed as a retrofit solution for the EOS P3 laser sintering machines.
    A high-resolution camera records each layer, which is analyzed by a Region-Based
    Convolutional Neural Network (Mask R-CNN). Over 2500 images were annotated and
    classified to train the network in detecting defects in the powder bed at a very
    high level. Each defect is checked for intersection with exposure areas. To distinguish
    between acceptable imperfections and critical defects that lead to part rejection,
    the impact of these imperfections on part properties is investigated.
