Additive manufacturing refractory metals and silicate materials

研究的重点是基于超短脉冲激光辐射的增材制造工艺。因此，工作区中的可调节能量分布适用于打印硅酸盐材料和难熔金属。目前的技术水平没有展示出实现不同研究任务的完整解决方案。现在，像选择性激光熔化（SLM）这样的工艺仅应用高斯和矩形光束分布。为了进一步优化所追求的材料特性，光束轮廓、阴影策略和层厚度的灵活变化是重要的。在这里，完全嵌入机器控制中的软件是必要的。复杂的光束整形需要监控所有相关的激光参数，以确保稳定和可再现的结果。完整的系统提供了在一个特殊的腔室中开发和分析打印过程的可能性。最后，申请人能够利用现有的虚拟工具和软件环境来模拟和优化整个环境。

The focus of research is the additive manufacturing process based on ultra-short pulse laser radiation. Therefore, an adjustable energy distribution in the working zone is applied to print silicate materials and refractory metals. The current state of the art does not exhibit a complete solution to realize the different research tasks. Now, processes like selective laser melting (SLM) only apply Gaussian and rectangular beam distribution. To further optimize the pursued material properties the flexible variation of beam profile, hatching strategy and layer thickness is important. Here, a software, which is completely embedded in the machine control, is necessary. The complex beam shaping requires the monitoring of all relevant laser parameters to ensure a stable and reproducible result. The complete system provides the possibility develop and analyse the printing process in a special chamber. Finally, the applicant is able to simulate and optimize the complete environment with existing virtual tools and software surroundings.
