This book creates a new perspective on the design of plastic parts. In many books there is a strong focus on the material, the material properties, and the calculation or dimensioning. What is often not taken into account is that very many plastic components only have to withstand low loads; in very many applications, the focus is on the actual design. This requires a good understanding of the injection molds that must be built to produce the plastic components. Depending on the design of the injection molded component, these molds become more complex and more prone to failure during production.The complex process of manufacturing a plastic part becomes holistically understandable as a link is created between the molder, the mold maker, and the part designer. The focus is on injection molds and therefore on thermoplastics.Everything that is necessary for the design and manufacture of an injection molded component is presented in a simple, extremely practical manner and limited to the essentials. Many descriptive pictures as well as examples based on the demonstration component ""Polyman"" facilitate the understanding enormously.

This book unites the two sides of additive manufacturing: 1) the technical aspect of 3D printing of very different materials and 2) the disruptive consequences for value chains between producers, intermediaries, and customers due to modern business models. This is because 3D printing breaks with many existing business models: companies take over functions from their previous suppliers (following the "do-it-yourself" trend), intermediaries lose their livelihood (so-called "disintermediation"), manufacturers move their production to decentralized locations (e.g., retailers, car dealerships, or hospitals, so-called "decentralized production"), and (end) customers become much more intensive "prosumers" than marketing (as creator of this term) could ever imagine.The business models of many existing companies from very different industries are becoming toxic, i.e., threatening their very existence, as in logistics and warehousing, industry, services, retail, or customer service. Conversely, there are also many opportunities for modern, existence-securing business models, which the book discusses in more detail. In this way, this book not only shows to a broad range of readers the dangers of disruptive 3D printing technology, but also offers solution approaches and procedural models for identifying new economic livelihoods and competitive advantages. Thanks to the collaboration of the two authors, a profound knowledge of already existing references and management models can be drawn upon.

This book offers a unique overview of usage of biomass, biomaterials, and bioproducts, including biopolymers. Included are materials, processes, usage as an energy source, and, in particular, applications. It is intended to educate both professionals and graduate students, who typically must acquire knowledge outside of traditional academic disciplines to gain an appreciation of these systems.While the growing need for renewable energy can be satisfied from other renewable sources, biomass is our only real source of renewable carbon-based chemicals and fuels. More and more companies are moving toward using these materials, and investing in new technology based on renewable resources to develop their businesses in a sustainable way.Despite this, few scientists and engineers have been appropriately trained to work in the interdisciplinary field of the biomass economy. Traditional academic disciplines are not well organized to train engineers and scientists to develop new bio-refinery concepts and bio-based products (including bio-based polymers) in industry, nor to develop and integrate pathways to convert biomass into other forms of energy and useful products. The integration of old and new pathways to satisfy global and local markets is the basic skill required to create new biomass processing alternatives. This book is written to fill this gap.
