SPECIAL SESSION 12
ADDITIVE MANUFACTURING: PROCESS CONDUCT, MATERIAL MODELLING, APPLICATION AND OPTIMIZATION
Parts are generated layer wise (nearly) without any restrictions regarding their shape and volume. While additive manufacturing (AM) is a well-known process for plastics, the 3D printing of metal is a relatively new discipline. This session aims to address the current challenges in AM of metals and metal/ceramic composites (e.g. hard metal), including preprocessing, fabrication, quality assurance and postprocessing.
One key focus are the inherent anisotropy and inhomogeneity in both the microscale and the macroscale. Material characteristics are prone to fluctuations, attributed to the process conduct (parameters and irradiation strategy), as well as the positioning and inclination in the fabrication process. Therefore, a precise dimensioning and topology optimization process necessitates a linkage to the manufacturing conditions.
Key factors for the further success of AM are seen in the comprehensive understanding of the microstructural development during fabrication and the resulting properties, and even more importantly, the possibility for their accurate prediction. Moreover, AM shines on hard to process materials due to the near-net shaping, leading to another important aspect of this session, the expansion of the material range towards the defect-free fabrication of high strength alloys for highly specialized applications, e.g. high strength tool steel, high entropy alloys, and more.
Apart from advanced and highly specialized applications AM offers an on-demand and location independent fabrication path, which can potentially solve challenges in spare part stocks, distribution and logistics.
