Abstract In this work, the machine dynamic response in Selective Laser Sintering is investigated with the purpose of determining the causes of scanning errors. Machine subcomponents are first investigated to determine their potential effects on the laser beam positional accuracy. The dynamics of the laser beam delivery system are identified as the major contributor to deviations in the laser beam position. The moving-iron galvanometer scanner used in SLS machines is then modeled, with the ultimate goal of understanding how its various components and parameters affect part scanning accuracy. This work should provide a better understanding of the dynamics of the laser beam delivery system and give insight on machine parameters that result in better part accuracy.
