Modeling and simulation of additively manufactured composites

Abstract

In modern manufacturing, additive manufacturing (AM) has become the dominant technique, surpassing traditional machining. Traditional machining poses challenges such as warping and internal stress, while rapid prototyping through AM offers cost-effective, precise, and efficient solutions. This approach is now widely used for complex design production, revolutionizing the manufacturing industry. This study delves into the realm of AM with a specific focus on composite materials, starting with exploring various 3D printing processes tailored for composites. The study discusses the modeling of 3D printing processes, laying the foundation for a comprehensive understanding of this transformative technology. Numerical simulation of printed parts navigates through the intricacies of micro-, macro-, and meso-scale modeling, offering valuable insights into the complex world of 3D printing. The study also scrutinizes the multifaceted factors that influence the characteristics of 3D-printed composites. These factors include interfacial bonding, the influence of loads and environmental conditions, and the pivotal role played by fiber content. Each facet contributes significantly to the overall performance and properties of printed composite materials. By exploring the modeling, simulation, and influencing factors, this study offers a roadmap for researchers and industry professionals to navigate the intricate landscape of 3D printing in composites, fostering innovation and advancements in this burgeoning field.
