Liu et al. have investigated the influence of laser scanning speed on the solidification of AZ-GdAlO3 eutectic ceramic during selective laser melting (SLM) technique. The relative density of the solidified samples was reported to decrease from 98.7% to 95.7% with increasing laser scanning speed to ~48 mm/min . In addition, it was observed that the primary heat transfer mechanism associated with the solidification phenomenon is thermal conduction due to which there was a decrease in both melting width and depth with increase in scanning speed . Interestingly, it was also observed that the eutectic spacing in the top zone of the melt pool initially decreases with increasing laser scanning speed from 6 mm/min till 12 mm/min and then increases with increasing scanning speed from 12 mm/min till 48 mm/min . The aforementioned trend in the eutectic spacing with scanning speed was attributed to a change in solidification rate controlling factor from laser scanning speed to the angle between the scanning direction and the growth direction of the microstructure , . Quenching induced micro-cracks and increased surface roughness (due to bailing effect and presence of microstructural pores) were reported for scanning speeds of <12 mm/min . Moreover, solidification defects were reported to be minimised for laser scanning speed of ~12 mm/min .
