Abstract
En 中文
• Cost-efficient in-situ inspection significantly reduces qualification efforts in additive manufacturing. • Detectability of geometrical deviations is demonstrated on L-PBF gyroid lattices of different sizes. • Proper calibration of image segmentation ensures robustness to variations in illumination, part sizes and geometry. • Directional deviation metrics enhance in-situ detection of real geometrical defects.
