Freedom of design, mass customisation, waste minimisation and the ability to manufacture complex structures, as well as fast prototyping, are the main benefits of additive manufacturing (AM) or 3D printing. A comprehensive review of the main 3D printing methods, materials and their development in trending applications was carried out. In particular, the revolutionary applications of AM in biomedical, aerospace, buildings and protective structures were discussed. The current state of materials development, including metal alloys, polymer composites, ceramics and concrete, was presented. In addition, this paper discussed the main processing challenges with void formation, anisotropic behaviour, the limitation of computer design and layer-by-layer appearance. Overall, this paper gives an overview of 3D printing, including a survey on its benefits and drawbacks as a benchmark for future research and development.

Additive manufacturing (3D printing): A review of materials, methods, applications and challenges

Additive manufacturing of metals

Additive manufacturing (AM), widely known as 3D printing, is a method of manufacturing that forms parts from powder, wire or sheets in a process that proceeds layer by layer. Many techniques (using many different names) have been developed to accomplish this via melting or solid-state joining. In this review, these techniques for producing metal parts are explored, with a focus on the science of metal AM: processing defects, heat transfer, solidification, solid-state precipitation, mechanical properties and post-processing metallurgy. The various metal AM techniques are compared, with analysis of the strengths and limitations of each. Only a few alloys have been developed for commercial production, but recent efforts are presented as a path for the ongoing development of new materials for AM processes.

Effects of Defects in Laser Additive Manufactured Ti-6Al-4V on Fatigue Properties

Automatisierte Bauteilsichtung und -selektion für die Luftfahrtindustrie

Abstract Der Artikel versucht, mit Hilfe einer genauen und ausführlichen narratologischen Analyse die Umsetzung der vielfältigen Entwürfe eines ,neuen Lebens‘ in den 1970er Jahren bei Henschel zu diskutieren. Dabei wird deutlich, dass den andauernden
 ideologischen Diskursen der deutschen Geschichte seit der Jahrhundertwende zwar eine stark subjektive negative Kritik entgegengestellt wird, die sich aber, dem noch sehr jugendlichen Alter des homodiegetischen Helden, aber auch den gesellschaftlichen Möglichkeiten der Zeit entsprechend,
 nur teilweise durchsetzen kann.
