The aim of this project is to facilitate additive manufacturing of bulk metallic components by selective laser melting based on predictive numerical simulations. There should be developed suitable process strategies to ensure the amorphous material state preferably without aging effects in the bulk as well as for complex geometries. Therefore, clear statements using the numerical simulation has to be made exceeding the temperature field and the material consolidation during manufacturing towards the solidification behavior, aging and finally crystallization.

该项目的目的是通过基于预测数值模拟的选择性激光熔化来促进块状金属部件的增材制造。应该开发合适的工艺策略，以确保非晶材料状态，优选地在本体中以及对于复杂的几何形状没有老化效应。因此，必须使用数值模拟对制造过程中的温度场和材料固结进行明确说明，以了解凝固行为、老化和最终结晶。
