Dynamic behavior of 3D printed beams

Abstract

One of the most widely used 3D printing methods is Fused Deposition Modeling (FDM). This method relies on the deposition of a heated polymeric material filament, that traces the desired geometry of the part to be fabricated. Although geometrically similar, parts manufactured by FDM have a different mechanical behavior than ones manufactured by more conventional machining methods, both in statically and dynamically. Even when comparing parts made by the same material, the results are different. This difference in behavior results mainly from how the material is deposited.
