This master thesis focuses on the development of a solution which makes possible the 3D printing of medicines. In fact, it is very difficult or even impossible to use the pharmaceutical materials with classical 3D printers. For this purpose, a new extrusion head is developed for a FDM 3D printer. The idea behind the new solution is the one of an extruder but very smaller. Such a solution was never mentioned in literature. Consequently, the mechanical, thermal and flow behaviour of the system had to be deeply studied. Once the design was fixed, the first prototype was fabricated. Extrusion tests were performed and the system was approved for one of the pharmaceutical materials. It could thus be integrated on the 3D printer to start the real printing tests.

Significant research efforts are currently being undertaken in the field of natural and synthetic polymers for a range of biomedical applications. (Co)polymer molecular structure, topology, self-assemblies, biodegradation, and hydrophobicity are of biomaterial importance for intrinsically biocompatible polymer systems. This book is comprised of nine chapters, published previously as original research contributions of the Special Issue focused on advances in polymeric materials for biomedical applications. The authors of these contributions are predominantly from central European countries, Italy and the United Kingdom. The content of this book will be of interest to scientists, scholars and students working in this area of knowledge, reflecting the progress in the development of advanced natural and synthetic polymer biomaterials.

Additive manufacturing technology offers the ability to produce personalized products with lower development costs, shorter lead times, less energy consumed during manufacturing and less material waste. It can be used to manufacture complex parts and enables manufacturers to reduce their inventory, make products on-demand, create smaller and localized manufacturing environments, and even reduce supply chains. Additive manufacturing (AM), also known as fabricating three-dimensional (3D) and four-dimensional (4D) components, refers to processes that allow for the direct fabrication of physical products from computer-aided design (CAD) models through the repetitious deposition of material layers. Compared with traditional manufacturing processes, AM allows the production of customized parts from bio- and synthetic polymers without the need for molds or machining typical for conventional formative and subtractive fabrication.In this Special Issue, we aimed to capture the cutting-edge state-of-the-art research pertaining to advancing the additive manufacturing of polymeric materials. The topic themes include advanced polymeric material development, processing parameter optimization, characterization techniques, structure–property relationships, process modelling, etc., specifically for AM.

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.
