Book Description
Laser Sintering (LS) with plastics is one of the most promising additive manufacturing technologies: it is currently regarded as the process most likely in the future to permanently cross the border between prototyping and the production of functional parts. This step is challenging because it means that the technology must meet certain requirements that are also valid for traditional and established production processes. Only by succeeding at this step can a wide industry acceptance of LS be expected in the future. In this context, this book covers all levels of the LS process chain, including: - Current state of the machine technology - Essential process steps, both before and during sintering - Specific demands of the materials, powder production methods, and evaluation of powder properties - Mechanical properties and density of the parts produced by LS Examples of LS-produced parts are given, including those with special design features, to illustrate the characteristics and also the limitations of the LS method. In particular, the distinct advantages of LS parts over parts produced with other plastics processing methods (e.g., injection molding) are discussed.

Book Description
Plastics: Microstructure and Applications is a key text for senior students studying the science and engineering of plastics materials (or polymers) and will serve as a valuable introduction to the fundamentals of polymer properties for those new to the field. Starting from microstructure and physical properties, the book covers the mechanical, chemical, transport and electrical properties of plastics materials and also deals in detail with wider issues that today's engineers and materials scientists need, such as manufacturing processes and the design of plastics products. A thorough revision of the book for this 4th edition reflects advances in the field by including more detailed discussion of characterization techniques, crystallization and molecular structure, thermoplastic composites, 3D printing and electrical properties of plastics. The chapter on materials and shape selection covers sustainability, life cycle analysis and waste disposal considerations for plastics materials. - Provides introductory information for students of plastics technology, materials science and engineering, mechanical engineering and other fields. - A useful introduction to the fundamentals of plastics for academic and industrial researchers from other fields. - Includes substantial new coverage of microstructure and morphology of polymers; electrical properties of plastics; modern additive manufacturing and consideration of sustainability and life cycle analysis of plastic materials.

Book Description
This comprehensive handbook provides a simplified, practical and innovative approach to understanding the design and manufacture of plastic products. It will expand the reader's understanding of plastics technology by defining and focusing on past, current, and future technical trends. The content is presented so that both technical and nontechnical readers can understand the interrelationships of materials to processes. Different plastic products are examined and their related critical factors are shown, from meeting performance requirements in different environments, to reducing costs and targeting for zero defects. Examples used include small to large, and simple to complex shapes. Information is included on static properties (tensile, flexural), dynamic properties (creep, fatigue, impact) and physical and chemical properties. Extensive reference sources and useful data and physical and chemical constants are also provided. Volume 2 offers detailed coverage of most major plastics processing techniques, including injection molding, extrusion, blow molding, and thermoforming.
