ABSTRACT
The most important applications for polymeric materials produced by three-dimensional (3D) printing are strain rates. 3D printed parts have higher crystallinity, improved fracture toughness, and higher strain rate sensitivity. The printed material's fracture toughness, which has been experimentally examined for its relationship to the strain rate effect in the literature, has a significant impact on the defect's ability to spread. The aim of the chapter is to give a summary of the impacts on mechanical characteristics of 3D printed parts made from pure materials, such as neat polymer and pure metal, or composites, such as fiber-reinforcement polymer composites, metal-polymer composites, etc., at high strain rates. It focuses on the basics of additive manufacturing (AM), how AM is categorized, the many kinds of materials used in 3D printing, and how components manufactured using different materials exhibit sensitivity to high strain rates. Through the chapter, a reader can obtain a general understanding of the importance of strain rate while analyzing the dynamic behavior of 3D printed parts made from different materials.
