Finite Element Analysis of a Leaf Spring Manufactured Using Fused Deposition Modeling (FDM)

Abstract

This chapter will introduce fused deposition modeling (FDM), a prominent 3D printing technology. It will begin by presenting the fundamentals of additive manufacturing, highlighting its scientific principles and significance as an innovative and emerging industrial technology. The chapter will also discuss key parameters that influence polymer melt deposition and their interaction with the structural properties of components. Additionally, it will provide an overview of the quality characteristics of FDM-produced items in relation to process parameters. Additive manufacturing, as described, involves the layer-by-layer deposition of materials to create three-dimensional (3D) parts using various technologies. These materials may include composites, metals, polymers, or concrete. For a manufacturing process to qualify as an additive manufacturing method, it must involve three essential elements: creating 3D visual models using computer-aided design (CAD) tools such as AutoCAD, Solid Works, and CATIA, which may be either open-source or proprietary; proficient use of multiple operating systems by engineers or designers working on these tools; and the ability to generate intricate 3D product designs through CAD applications. Critical factors influencing the additive manufacturing process include the material consumption and the time required by the 3D printer to produce the final product
