Modules

Prerequisites

Contents

Fundamentals of welding engineering and additive manufacturing technologies with particular attention to powder bed fusion and directed energy deposition. Design and Construction of 3D printed parts. Microstructure evolution during the build process and postprocessing. Modelling and numerical simulation in additive manufacturing processes, in particular part-scale thermo-mechanical models to predict thermal stresses and distortions in powder bed fusion. Knowledge is applied in a project using commercial software (Simufact.Additive) to analyze the influence of build orientation and support structures on final build quality.

Learning outcomes

The students will • gain systematic knowledge of the physical and technological fundamentals of welding engineering in view of additive manufacturing technologies, • be able to describe relevant additive manufacturing technologies and will know their respective strengths and weaknesses, • have a critical understanding for the selection of appropriate additive manufacturing technologies based on the specific task, • learn the basics of the finite element method and part-scale modelling techniques to predict residual stresses and distortions.

Assessment

• Final presentation, ~30 min. (30%) and • Written exam, 60 min. (70%)
