Validation Study of an Analytical Model of FDM Accuracy

Abstract

The diffusion of Additive Manufacturing technologies is leading to new needs in industrial research and development sectors. In particular, mating additive manufactured parts is not a simple task, due to the poor accuracy of several additive technologies, such as Fused Deposition Modeling (FDM). Several papers are focused on studies of how FDM accuracy is affected by process parameters. In this paper the authors report a study of the influence of working parameters on FDM dimensional accuracy, paying particular attention to variables that can affect axial symmetric mating between parts, and how these parameters can be set to improve the mating process.
