Macroscopic modeling, simulation, and optimization of the selective beam melting process (C03)

子项目的目的是将聚合物（LSS-K），金属（LSS-M）和电子束熔化（SEBM）的束熔化过程的模拟工具从前两个资助期扩展到分层模拟环境，以开发和鉴定问题和零件适应的模拟策略。这需要应用简化的物理模型、减少误差的补偿策略和有效的算法，例如自适应多速率时间积分器。过程模拟（高达1000 cm3的零件）将支持具有定义属性的零件的可重复生产的过程控制。

The aim of the sub-project is to extend the simulation tool for beam melting process of polymers (LSS-K), of metals (LSS-M) and electron beam melting (SEBM) from the first two funding periods to a hierarchical simulation environment in order to develop and qualify problem- and parts-adapted simulation strategies. This requires the application of reduced physical models, compensation strategies for error reduction and efficient algorithms, e. g. adaptive multi-rate time integrators. The process simulations (for parts up to 1000 cm3) will support the process control for the reproducible production of parts with defined properties.
