Sub-project B1 deals with the simulation of the powder recoating process for laser beam melting of polymers. The focus here is the investigation of the recoating mechanism by means of realistic discrete element method (DEM) simulations considering the particle shape and the thermomechanical properties of the powder, as well as the influence of multiple recoated layers and molten region. The aim is to derive optimized time-sensitive recoating strategies and the study of alternative mechanisms that can be tested in practice to improve the quality of the manufactured component.

子项目 B1 涉及激光束熔化聚合物的粉末重涂过程的模拟。这里的重点是通过真实的离散元法（DEM）模拟来研究重涂机制，考虑粉末的颗粒形状和热机械性能，以及多个重涂层和熔融区域的影响。目的是导出优化的时间敏感重涂策略，并研究可在实践中进行测试的替代机制，以提高制造部件的质量。
