3D printing is rapidly emerging as a key manufacturing technique that is capable of serving a wide spectrum of applications, ranging from engineering to biomedical sectors. Its ability to form both simple and intricate shapes through computer-controlled graphics enables it to create a niche in the manufacturing sector. Key challenges remain, and a great deal of research is required to develop 3D printing technology for all classes of materials including polymers, metals, ceramics, and composites. In view of the growing importance of 3D manufacturing worldwide, this Special Issue aims to seek original articles to further assist in the development of this promising technology from both scientific and technological perspectives.

Additive manufacturing (AM), more commonly known as 3D printing, has grown trememdously in recent years. It has shown its potential uses in the medical, automotive, aerospace, and spare part sectors. Personal manufacturing, complex and optimized parts, short series manufacturing, and local on-demand manufacturing are just some of its current benefits. The development of new materials and equipment has opened up new application possibilities, and equipment is quicker and cheaper to use when utilizing the new materials launched by vendors and material developers. AM has become more critical for the industry but also for academics. Since AM offers more design freedom than any other manufacturing process, it provides designers with the challenge of designing better and more efficient products.

Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers, and scientists. AM has the ability to fabricate materials to produce parts with complex shapes without any theoretical restrictions combined with added functionalities. Selective laser melting (SLM), also known as laser-based powder bed processing (LPBF), is one of the main AM process that can be used to fabricate wide variety of materials that are Al-, Ti-, Fe-, Ni-, Co-, W-, Ag-, and Au-based, etc. However, several challenges need to be addressed systematically, such as development of new materials that suit the SLM process conditions so the process capabilities can be fully used to produce new properties in these materials. Other issues in the field are the lack of microstructure–property correlations, premature failure, etc. Accordingly, this Special Issue (book) focuses mainly on the microstructure-correlation in three different alloys: AlSi10Mg, Ti6Al4V, and 304L stainless steel, where six articles are presented. Hence, this Special Issue outlines microstructure–property correlations in the SLM processed materials and provides a value addition to the field of 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.
