Effects of Process Strategies on the Processability of CM247LC in Powder Bed Fusion of Metals using a Laser Beam

In this work, the processability of the nickel-based superalloy CM247LC in powder bed fusion of metals using a laser beam (PBF-LB/M) is systematically investigated. The focus is on the influence of inter-hatch waiting times and hatch permutation patterns. A baseline parameter set was established in preliminary studies to ensure a stable melt pool formation and defect-free consolidation. Based on these findings, the effects of controlled temporal delays between adjacent vectors and variations in hatch sequence are studied. The samples are analyzed in terms of relative density and the mean peak temperature of each layer, recorded using an in-situ thermographic camera system.
