Additive Manufacturing creates added value for agile production and optimized products. The highly dynamic developments in Additive Manufacturing technology are not only driving academic research. Industry is also intensively working on integrating the advantages of these opportunities into established conventional production and value creation processes. The comparatively young age of additive technologies, the generally high complexity of the property-determining processes and the resulting implications for the economically and technologically effective use of additive technology pose major challenges for potential industrial users. The transfer of knowledge from academic research into industrial application plays a decisive role to better exploit the potential of Additive Manufacturing processes for the production technologies of the future.

In this context, the annual event Rapid.Tech 3D is a valuable platform for connecting established and new users of Additive Manufacturing. This year’s Rapid.Tech took place from 14 to 16th of May 2024 in Erfurt, Germany. The combination of scientific conference, trade exhibition and networking events has been accelerating the transfer of knowledge to industry for 20 years now.

For this Special Issue the 16 best contributions from this conference were accepted for publication. They were selected through a high-quality scientific peer review process from a total of 39 submission and are characterized by particularly innovative research concepts and novel findings from ongoing research activities.

The contributions address different process related and material science aspects of the Additive Manufacturing processes Powder Bed Fusion (PBF-LB/M and PBF-LB/P), Material Extrusion (MEX), Binder Jetting (BJ) and Directed Energy Deposition (DED). In addition to the development, qualification, and characterization of novel materials, such as Bulk Metallic Glasses, Multi-Materials and Composites, the contributions also highlight innovative process strategies, methods for surface treatment of additively manufactured components, thermal simulation and modelling of manufacturing processes as well as the potential for digitalization along the process chain. We would like to thank PIAM editor Dr Eujin Pei, as well as Jutta Daum and Durga Raghu from Springer Nature very much for their support in creating this Special Issue.

We hope you enjoy reading this special issue and look forward to continuing the cooperation between the journal PIAM and Rapid.Tech 3D in the future for coordinated and targeted knowledge transfer for Additive Manufacturing.
