42. On the importance of surface engineering and conditioning of additively manufactured particle-accelerator components

Maurizio Vedani (Politecnico di Milano)

Metal additive manufacturing (AM), especially laser-based powder bed fusion, enables the fabrication of components with complex geometries and high functional integration, but typically results in relatively rough as-built surfaces. Surface quality is especially critical for particle accelerator components, such as those subjected to radiofrequency, where skin effects become increasingly...

38. Advancements in Multi-Material Powder Bed Fusion of Metals Using a Laser Beam

Producing complex multi-material components using conventional technologies is challenging, time-consuming, and often uneconomical due to additional manufacturing steps and increased costs. Multi-material powder bed fusion of metals using a laser beam (MM PBF-LB/M) opens up new possibilities for processing several materials in a single manufacturing step and can significantly enhance...

52. Improving dimensional accuracy in metal AM through simulation-based distortion compensation

Stefan Brenner (Universität der Bundeswehr München)

PBF-LB/M is a well-established manufacturing process for high-performance metal components, but achieving tight dimensional tolerances remains challenging. Thermo-mechanical finite element simulations offer a means to predict and compensate for process-induced distortion. We present a simulation approach based on advanced constitutive modelling that does not require geometry-specific model...

63. Investigation of the influences of process parameters in the selective laser melting process and development of a strategy for the manufacture of test specimens made of CuCr1Zr on a large-scale system with an infrared laser source

Additive manufacturing, in particular the selective laser melting process, is ideally suited to the production of highly complex geometries. There is a clear trend towards increasing component size whilst maintaining high quality and, at the same time, minimising production time. As part of my work, I succeeded in achieving relative densities of over 99.5 % using a large-format system with an...

44. Hirtisation – Metal AM post-processing for complex geometries

Michael Doppler

19/10/2026, 16:40

Hirtisation is a family of chemical/electrochemical post-processing techniques developed for additively manufactured metal parts. Hirtisation aims to remove surface adherent particles, support structures, and reduce surface roughness. Since treatment only requires liquid-part contact complex geometries including hollow chambers and channel systems can be treated in addition to external...
