Investigation on Reasons Inducing Error and Measures Improving Accuracy in Fused Deposition Modeling

Abstract

Fused deposition modeling (FDM) is gaining distinct advantage in manufacturing industries because of its ability to manufacture part with complex shapes without any tooling requirement and human interface. But it is difficult to achieve higher precision part, improving part quality in FDM is one of the important concern. The part errors during in FDM are classified as dimension error, shaped error and roughness of surface. The shaped errors have many forms in fused deposition modeling (FDM), largely including war page deformation, stair-stepping effect, and so on. There are several reasons for the errors, including principle, process and equipment. The reasons inducing these errors are analyzed, and the measures improving part accuracy are proposed.
