3D printing

The manufacturing share of laser powder bed fusion (L-PBF) increases in industrial application, but still many process steps are manually operated. Additionally, it is not possible to achieve tight dimensional tolerances or low surface roughness. Hence, a process chain has to be set up to combine additive manufacturing (AM) with further machining technologies. To achieve a continuous workpiece flow as basis for further industrialization of L-PBF, the article presents a novel substrate system and its application on L-PBF machines and post-processing. The substrate system consists of a zero-point clamping system and a matrix-like interface of contact pins to be substantially connected to the workpiece within the L-PBF process.

Additive manufacturing technologies, such as 3D printing, have reached a stage of performance for industrial application such as small series and spare parts. The adoption of additive manufacturing has so far mostly been investigated from the perspective of individual manufacturing firms. This paper focuses on the identification of overarching influence factors. In a category system, influence factors are analyzed from the perspectives of the supply and demand side, the supply chain actors and flows as well as sustainability, thus contributing to the adoption from a supply chain perspective.

Additive Manufacturing (AM), also commonly called 3D-Printing, is very recent technology. Numerous innovations have improved their capabilities in the last few years. These improvements combined with ambitious promises made by 3D-Printing companies have led to some disregard of the physical and economical limitations of these technologies. As impressive as the opportunities especially in light weight construction may be, the technical, physical and economical restrictions have to be considered. This article focuses on the premises and restraints as well as the opportunities of AM-technology.

Additive manufacturing is today increasingly used to produce final products and not only prototypes in product development. Like many technologies before breakthrough it is mainly applied in niche markets, where it is overcoming its current limitations. Afterwards, it has the potential to transform industries as MP3 and iPod have done with the music business. The economist even speaks of the next industrial revolution [1]. This article supports companies in evaluating the strategic implications of additive manufacturing of final products in the mid- to long-term.
