The mesoscopic scale allows the investigation of phenomena resulting from the complex interplay between beam, powder and melt. On the one hand, the numerical simulation tool, which has been restricted on metals so far, will be extended by a model for semi-crystalline thermoplastics in order to make it applicable on polymers. On the other hand, a 3D grain growth model will be implemented in order to predict the local texture of metallic components. Numerical experiments will be per-formed in order to support the experimental projects in developing innovative processing strategies.

介观尺度可以研究光束、粉末和熔体之间复杂相互作用所产生的现象。一方面，迄今为止仅限于金属的数值模拟工具将通过半结晶热塑性塑料的模型进行扩展，以使其适用于聚合物。另一方面，将实施 3D 晶粒生长模型以预测金属部件的局部纹理。将进行数值实验，以支持开发创新加工策略的实验项目。
