Fundamentals of Additive Manufacturing

Additive manufacturing (AM) is the innovative process of constructing three-dimensional objects from a computer model by depositing successive layers of material. This cutting-edge technology has gained prominence since the late 1980s as a means to fabricate intricate components and spare parts. The benefits of AM are numerous, including reduced material wastage, streamlined manufacturing processes, decreased human intervention, minimized tool and fixture needs, and limited post-processing requirements. These advantages make AM a sustainable and efficient solution for a wide range of industrial applications. Fundamentals of Additive Manufacturing: Principles, Technologies, and Applications provides a comprehensive overview of AM techniques, including their concepts, features, and historical background. It delves into software issues such as the Standard Triangle Language (STL) and the concept of "tessellation." The textbook categorizes AM techniques according to ASTM F42-Committee standards and explains the basics and principles in a straightforward manner. It covers technologies for AM of polymers, composites, metallic materials, and ceramics in detail. Additionally, it discusses design for AM, post-processing, feedstock materials, the impact of AM on conventional manufacturing processes, and Industry 4.0. Cost analysis and environmental considerations related to AM techniques are also addressed. A focus is placed on the Aerospace, Automotive, Biomedical, Electronics, and Jewelry industries, highlighting future trends in Lattice Structures and 4D printing. The textbook concludes with a discussion on challenges, needs, and recommendations for the future of additive manufacturing. This textbook is specifically tailored for undergraduate students in mechanical, industrial, manufacturing, and materials engineering programs at the second to fourth levels. The content is designed to meet the needs of production and manufacturing engineers, as well as technologists working in AM and related industries with a goal to provide a deep understanding of AM technology as it is taught in engineering colleges worldwide. In addition, students in related fields such as automotive, biomedical, and aerospace engineering can find valuable information in this textbook. PowerPoint slides are available for qualitied textbook adoption.
