In-process sensing in selective laser melting (SLM) additive manufacturing (2016, background): “Visual camera images taken after the completion of laser scanning on a given layer may be used to evaluate errors related to the part geometry, superelevation of the part above the powder bed due to thermal stresses, and support connection errors in a that layer [65, 66].”
A review on quality control in additive manufacturing (2018, methodology): “Kleszczynski et al. (2012) used a high resolution CCD camera for surface error detection through image processing, as shown in Figure 12 (Kleszczynski et al., 2012).”
Measurement Science Needs for Real-time Control of Additive Manufacturing Powder Bed Fusion Processes (2015, methodology): “used a high resolution CCD camera with a tilt and shift lens to correct the image mounted on the observation window of a commercial PBF machine [74].”
