Printing parameters and materials affecting mechanical properties of FDM-3D printed Parts: Perspective and prospects

Abstract

Additive Manufacturing has become one of the primary advances of the fourth industrial revolution. Fused Deposition Modelling (FDM) is one of the most widely used additive manufacturing processes for various applications. In light of the growing demand for environmentally friendly developments, this article provides a comprehensive review of the printing parameters directly influencing the mechanical properties such as tensile strength, stress, Young’s modulus on the parts produced by FDM. In this article, the most crucial printing parameters, namely layer thickness, infill density and pattern, printing speed, build orientation, and raster angle affecting mechanical properties, are considered for the study. The information regarding various materials used in the FDM process is also given in detail. The article details the effect of different printing parameters on tensile strength, flexural strength, and Young's modulus.
