Discover the ins and outs of additive manufacturing in this student-friendly textbook

Also known as 3D printing, additive manufacturing is a process by which layers of material are added to create three-dimensional objects guided by a digital model. It has revolutionized the design and manufacture of customized products, facilitating the rapid, flexible production of a huge range of goods. It promises to revolutionize manufacturing engineering, shorten industrial supply chains, and more.

Theory and Practice of Additive Manufacturing provides the first introduction to this subject designed specifically for students. Balancing the underlying theories behind additive manufacturing with concrete applications, it guides readers through basic processes, essential tools and materials, and more. The result is essential for readers looking to bring additive manufacturing to bear on engineering or industry careers of almost any kind.

Theory and Practice of Additive Manufacturing readers will also find:
* Over 100 worked-out example problems
* Detailed discussion of the emerging digital tools including mechanistic modeling, machine learning, and more
* Commitment to pedagogy and reinforcement geared towards student learning outcomes

Theory and Practice of Additive Manufacturing is ideal for undergraduate and graduate students and instructors in introductory additive manufacturing courses, as well as practicing engineers and researchers working in industries that use additive manufacturing technologies, including aerospace, automotive, and consumer goods.
