Comparative between FEM Models for FDM Parts and their Approach to a Real Mechanical Behaviour

Abstract

Laminated parts made of FDM (Fused Deposition Modeling) are becoming increasingly popular in last years. This increment can be explained due to their potential in field of manufacturing in order to allow us to make any kind of geometry, but in another way, these parts have not enough values of stiffness and strength to get an approach to a final constructive part. However, advantages of nowadays FEM programs allow us to analyze behavior and main manufacturing properties; in order get previously mentioned structural parts. Then it we must need to accurately predict the response of composite structures to different load cases. In this way, the adequate modeling tools must be developed. The motivation of this article is to contribute to this development, making numerical simulations of two different composite structures with a ply-level approach, and analyze obtained results.
