The Laser Powder Bed Fusion (LPBF) process for metals is already widely used today for the additive production of industrial components. In order to find the optimum settings for 3D printing in terms of printing speed, porosity and ultimately costs, the most important machine parameters – such as laser energy, laser speed or even hatch patterns – are determined by means of many test prints and their metallurgical examination. Supplementing these experiments with simulation of the melt pool and hatch strategy for various parameter combinations, the process can be significantly accelerated and thus development costs can be drastically reduced.
This course is suitable for you if you have purchased a new metal powder bed machine and want to optimize the printing parameters. Also, developers of metal powder bed machines will learn how to improve their standard parameters for different materials. In addition, researchers can work on the relationship between energy density and porosity of various metal alloys.
Based on theory, practical exercises and workflows you will learn a procedure to find better process parameters and scanning strategies. You will use simulation in Ansys Additive Science to investigate the influence of laser parameters on the melt pool for a wide variety of metal powders. You will simulate how the scanning strategy can influence the porosity of a component.
