Abstract

The last three decades have seen the emergence and evolution of new manufacturing technologies that offer the benefits of complexity, cost and especially speed. The most notable process is additive manufacturing, which involves the construction of an object layer by layer from its numerical model, the revenue it generates has exploded, from euro 1 billion in 2009 to over euro 4 billion in 2014 according to the Wohler report 2015. For a company like Valeo which invests heavily in research and development, it is essential to take advantage of these new technologies for their prototyping needs. Heat exchanger is one of the leading products of Valeo THS, for a new design of its plates, it takes up to 44 euro k and 8 weeks to have the first functional parts using conventional technologies. While, with a judicious combination of new electromagnetic or hydraulic forming technologies, with tooling produced by additive manufacturing, costs can be reduced by half. However, the new design rules, still unclear do not allow to improve production lead times.

Abstract

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.

Abstract

Long description: Der Einstieg in die Additive Fertigung (AM) von Serien- und Endkundenteilen ist für viele Unternehmen eine Herausforderung: Standards, Dimensionierungsgrundlagen, Konstruktionsmethoden, technisch-wirtschaftliche Berechnungsgrundlagen, CAD-Tools und Erfahrung für die Entwicklung von additiven Serien- und Endkundenteilen existieren zum Großteil noch nicht oder sind wenig etabliert. Industrieunternehmen, die das Ziel haben, additiv gefertigte Endkundenteile zu entwickeln, sehen sich schnell ähnlichen Fragestellungen gegenüber. Mit praxisorientierten Methoden und Beispielen greift das Buch diese Fragen auf: Welche AM-Verfahren gibt es und welche eignen sich für industrielle Endkundenbauteile? (Kap. 2) Wie können AM-Verfahren mit konventioneller Fertigung kombiniert werden? (Kap. 3) Wie sieht die digitale Prozesskette aus? (Kap. 4) Welche Qualität haben AM-Bauteile und wie kann sie geprüft werden? (Kap. 5) Wie sieht die Kostenstruktur von AM-Bauteilen aus? (Kap. 6) Was sind etablierte Anwendungsfelder für AM? (Kap.7) Wie können potentialträchtige Bauteile und Anwendungsfelder der AM identifiziert werden? (Kap. 8) Wie werden Bauteile für AM optimal konstruiert? (Kap. 9) Was sind Beispiele von erfolgreich implementierten AM-Endkundenbauteilen? (Kap. 10) Wie sehen die Schritte aus, mit denen sich AM erfolgreich im Unternehmen implementieren lässt? (Kap. 11) Das Buch ist ein Grundlagenwerk für die industrielle Entwicklung und Konstruktion von additiv gefertigten Serien und Endkundenteilen, indem es praxisgerecht Methoden und Wissen bereitstellt, die eine erfolgreiche Implementierung additiver Verfahren in Unternehmen unterstützen. Neben neuen Methoden und Vorgehensweisen zeigt das Buch anschaulich Möglichkeiten der Implementierung anhand einer Vielzahl von erfolgreichen Produktbeispielen aus der Industrie. Long description: Dieses Grundlagenwerk für die industrielle Entwicklung und Konstruktion von additiv gefertigten Serien- und Endkundenteilen stellt praxisgerecht neue Methoden, Wissen und Vorgehensweisen bereit, die eine erfolgreiche Implementierung additiver Verfahren in Unternehmen unterstützen.
