Additive manufacturing refractory metals and silicate materials

研究的重点是基于超短脉冲激光辐射的加法制造工艺。因此，工作区内的可调节能量分布被应用于印刷硅酸盐材料和难熔金属。目前的技术水平并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)这样的过程只应用高斯和矩形光束分布。为了进一步优化所追求的材料性能，波束轮廓、阴影策略和层厚度的灵活变化是重要的。这里，需要一个完全嵌入到机器控制中的软件。复杂的光束整形需要监控所有相关的激光参数，以确保获得稳定和可重复性的结果。完整的系统为在一个特殊的腔室中开发和分析印刷过程提供了可能。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完整的环境。

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.
