Advanced Simulation Technologies in Additive Manufacturing

Bernhard Peters, University of Luxembourg

Additive manufacturing, also known as 3D printing, has only recently emerged as one of the most promising technology for manufacturing structures of virtually any shape. Products based on additive manufacturing span a large range of applications such as lightweight components for the aerospace and automotive industry or patient specific implants for medical applications. During the manufacturing process materials ranging from ceramics via thermoplastics to metal based powders, are exposed to often severe mechanical and thermal loads including phase transitions dependent on the processing conditions. In order to gain a deeper insight into the various processes and underlying physics, versatile simulation technologies have to be developed to understand the influence of many governing parameters e.g. temperature or printing velocity on the final quality of the final part. The mini-symposium aims at bringing together engineers and researcher from the applied e.g. industry and scientific community and providing a lively exchange of ideas regarding state of the art and future needs for simulation technologies in additive manufacturing. Therefore, topics of the mini-symposium on “Advanced Simulation Technologies in Additive manufacturing” in the broad sense will include:

Mathematical formulation

Numerical methods and implementation issues

Solution strategies

Multi-scale techniques

Multi-physic approaches

Artificial intelligence e.g. machine learning

Validation, verification and uncertainty quantification (VVUQ)

Metallurgical models

Large scale simulation

Industrial applications

 

key words: Euler/Lagrange methods, machine learning, high performance computing
