Book Description
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.

Book Description
Structure and Properties of Additive Manufactured Polymer Components provides a state-of-the-art review from leading experts in the field who discuss key developments that have appeared over the last decade or so regarding the use of additive manufacturing (AM) methods in the production of neat and reinforced polymeric components. A major focus is given to materials science aspects, i.e., how the quality of the polymer preforms, the parameters of the chosen AM method, and how these factors can affect the microstructure and properties of the final product. The book not only covers production technologies and the relationship between processing, microstructure and fundamental properties of the produced parts, but also gives readers ideas on the use of AM polymer parts in medicine, automotive, aerospace, tribology, electronics, and more. - Focuses on industrial aspects and applications - Dedicated purely to recent advances in polymer composite additive manufacturing - Emphasizes processing, structure and property relationships

Book Description
The field of additive manufacturing has seen explosive growth in recent years due largely in part to renewed interest from the manufacturing sector. Conceptually, additive manufacturing, or industrial 3D printing, is a way to build parts without using any part-specific tooling or dies from the computer-aided design (CAD) file of the part. Today, mo

Book Description
"Additive manufacturing (AM) is a potentially disruptive technology, revolutionizing not only traditional industries but generating entirely new ones through rapid innovation, the democratization of manufacturing, and unprecedented freedom of design. Furthermore, the development of AM technologies has practical implications for economic growth, healthcare, national security, space exploration, and sustainability. For military and space agencies, AM offers the possibility to transform the traditional supply chain system through manufacturing at-point-of-demand, recycling, and indigenous sourcing of raw materials. Similarly, these concepts are being leveraged by remote communities across the globe through efforts such as Fab Labs, which provide low-cost access to manufacturing technologies. AM is transforming healthcare in unexpected ways: doctors and patients have access to high-quality physical 3D models generated directly from computerized tomography (CT) scans. These surgical guides have proved invaluable in surgical preparation and patient consent. In the lab, researchers are developing medical devices or implants which mimic the patient's physiology, are pre-loaded with therapeutics, and are replaced with the patient's cells through natural tissue repair pathways. Pushing the limits of resolution, multi-photon technologies, which allow subdiffraction-limited resolution, are revolutionizing the development of micro-optical components. Unfortunately, adoption of AM technologies by industry has been slow; and while there are numerous success stories and commercial adoption is steadily increasing, AM is hampered by weak parts, incomplete certification methods, and empirical materials development. Regulatory and standards bodies are working to update or develop new standards and policies to deal with the unique material and production issues posed by AM. Many of the challenges facing the industry stem from our limited understanding of structure-process-performance relationships. These challenges fall into many categories and require a broad range of skills to address. For the researcher, AM processes offer unique challenges in materials development, metrology, and modeling, as well as opportunities to combine all three. What makes a polymer printable? What process parameters are important? How should parts be tested? These are all active areas of investigation. This book was inspired by the 2017 ACS Symposium "Additive Manufacturing of Structures and Functional Devices: Materials, Methods, Models, and Testing" and is supplemented by additional experts in the polymer AM field. The chapters discuss the technologies, measurement challenges, manufacturing opportunities, and fabrication potentials. We begin with an introduction to polymer additive manufacturing, identifying the measurement needs and technical challenges facing the industry. A chapter reviewing polymer powder bed fusion follows, providing a complete discussion on methods, materials, and applications. The bulk of the book covers thermoplastic material extrusion, with chapters discussing recycling-based feedstocks, composites materials, and multi-physics modeling linking experimentation and theory. Moving from thermoplastics to conductive inks, a chapter on in situ monitoring and control of direct-ink-write provides a clear example of how theory and modern machine vision can be used to create a practical and responsive control system. The last chapter provides a state-of-the-art review of multi-photon printing, discussing methods, materials, and the stunning capabilities of the technique"--

Book Description
Materials Processing: A Unified Approach to Processing of Metals, Ceramics and Polymers, Second Edition is the first textbook to bring the fundamental concepts of materials processing together in a unified approach that highlights the overlap in scientific and engineering principles. It teaches students the key principles involved in the processing of engineering materials, specifically metals, ceramics and polymers, from starting or raw materials through to the final functional forms. Its self-contained approach is based on the state of matter most central to the shaping of the material: melt, solid, powder, dispersion and solution, and vapor. With this approach, students learn processing fundamentals and appreciate the similarities and differences between the materials classes. This fully updated edition includes expanded coverage on additive manufacturing, as well as adding a new section on machining. The organization has been modified and a greater emphasis has been placed on the fundamentals of processing and manufacturing methods. This book can be utilized by upper-level undergraduates and beginning graduate students in Materials Science and Engineering who are already schooled in the structure and properties of metals, ceramics and polymers, and are ready to apply their knowledge to materials processing. It will also appeal to students from other engineering disciplines who have completed an introductory materials science and engineering course. - Includes comprehensive coverage on the fundamental concepts of materials processing - Provides coverage of metals, ceramics, and polymers in one text - Presents examples of both standard and newer additive manufacturing methods throughout - Gives students an overview on the methods that they will likely encounter in their careers
