Materials and manufacturing are the critical enabler of our technological world. With new materials and advanced manufacturing, new opportunities for advanced application become possible. Additive manufacturing (AM), or three-dimensional (3D) printing, is a relatively new manufacturing process, which relies on building up of parts from raw material. It reduces manufacturing waste, is flexible in part output, and opens new final part form-factors/architectures to be accessible for advanced applications. Light-based AM is well established in its ability to fabricate complex 3D structures whose unique properties exceed or are unfound in natural materials, called metamaterials. These unique 3D structures and other benefits of light-based AM make it of increasing interest for fabrication of functional devices, energy storage, sensors, and actuators among others. However, the available materials compatible with light-based AM, and AM in general, is limited. Specific material and processing limitations, viscosity, light absorption, and their underlying chemistry exclude the vast majority of materials from use in light-based AM. The majority of usable materials are on acrylic, vinyl, and thiol-based organic polymers whereas most functional materials are inorganic and not directly compatible.This dissertation focuses on the development of new materials and processes to allow the light-based AM fabrication of functional materials. This includes graphene energy storage devices, patterned 3D deposition for freeform electronics of multiple materials (conductors, dielectric, magnetic), and high-temperature ceramics for lightweight structural electronics in extreme applications. This dissertation lays the foundation for integrating light-based AM methods to electronic device applications that incorporates conducting and dielectric materials in 3D. Further development can allow advanced antenna, bioelectronics, and structural electronics.

This book is tailored designed for both researchers as well as academics teaching or introducing Advanced Manufacturing course to their classrooms. It presents the current state of research in this field of research and major challenges identified so far, for the integration of additive manufacturing into chemical processes. Unique capability of transforming materials into functional devices with specific geometry using the emerging additive manufacturing technologies has stimulated significant interest in biology, engineering and materials science, to provide custom-made designs for tailored applications. However, the applications of this emerging technology in the field of chemical sciences and engineering have started very recently. Therefore, the major focus of this book is to introduce the basic principles of additive manufacturing practices as well as advent into conventional chemical processes and various unit operations. The potential advantage of introducing these additive manufacturing technologies has the potential to scale down large scale chemical processes into small scale, which offers several advantages including lower foot print, waste reduction and efficient heat integration as well as distributed chemical manufacturing.

Additive manufacturing (AM) methods have grown and evolved rapidly in recent years. AM for polymers is an exciting field and has great potential in transformative and translational research in many fields, such as biomedical, aerospace, and even electronics. Current methods for polymer AM include material extrusion, material jetting, vat polymerisation, and powder bed fusion. With the promise of more applications, detailed understanding of AM—from the processability of the feedstock to the relationship between the process–structure–properties of AM parts—has become more critical. More research work is needed in material development to widen the choice of materials for polymer additive manufacturing. Modelling and simulations of the process will allow the prediction of microstructures and mechanical properties of the fabricated parts while complementing the understanding of the physical phenomena that occurs during the AM processes. In this book, state-of-the-art reviews and current research are collated, which focus on the process–structure–properties relationships in polymer additive manufacturing.

The field of additive manufacturing is growing dynamically as the interest is persisting from manufacturing sector, including other sectors as well. Conceptually, additive manufacturing is a way to build parts without using any part-specific tooling or dies from the computer-aided design (CAD) file of the part. Second edition of Additive Manufacturing highlights the latest advancements in the field, taking an application oriented approach. It includes new material on traditional polymer based rapid prototyping technologies, additive manufacturing of metals and alloys including related design issues. Each chapter comes with suggested reading, questions for instructors and PowerPoint slides.
