151-0740-00L | Metal Additive Manufacturing – Fundamentals and Process Technology | 4 credits | 2V + 2U | M. Bambach, L. Deillon, A. K. Eissing | |
Abstract | This lecture gives an introduction to the fundamentals and process technology of additive manufacturing processes with a focus on metals. The principles and technologies of laser powder bed fusion, directed energy deposition as well as sintering processes will be introduced. | ||||
Learning objective | The students will learn - the physics of the most important metal additive manufacturing processes including the interaction of energy sources (laser, electron beams, arc/plasma) and metals, the phenomena occurring during melting and solidification, the generation of stresses and defects - the capabilities and limits of these processes - the digital aspects of the process chains including preparation of geometries, slicing, hatching etc. including assessment of printability of a design - working principles of machines, equipment and technology - basics of sensors and process control - post processing steps and interaction with AM material - future trends in metal AM | ||||
