The formed metal cup samples and punches show 4 cup-shaped components positioned beneath matching cylindrical punches. A magnified inset on the left highlights a surface defect labelled Blob, with a red arrow and circle indicating the defect location on one punch. The cups display varying dome geometries and surface markings, while the punches are labelled with test identifiers related to infill density and manufacturing conditions.Visual inspection of the 10th produced cup and corresponding punches: from left, G35, T35, G50, T50
