Laser Powder Bed Fusion (LPBF) of Steel Elements for Construction – Basics of Design and Mechanical Resilience (A06)

首先，第一个资助期的结果，即工艺参数、材料表征、静态和动态试验方法，将转移到新材料中。为此，将选择比316L具有更高强度和更低CO2平衡的高锰奥氏体不锈钢。下一步将集中于将LPBF元素整合到大型结构中。这将包括开发一种基于过程监测预测疲劳寿命的方法。此外，还将研究LPBF连接元件的定制刚度如何用于控制结构内的全局荷载分布。在整个项目中，将考虑和量化LPBF要素的可持续性方面。

First, the results of the 1st funding period, i.e. process parameters, material characterization, static and dynamic test methods, will be transferred to a new material. For this purpose, a high-manganese austenitic stainless steel with higher strength and lower CO2 balance than 316L will be selected. The next step will focus on the integration of LPBF elements into large-scale structures. This will include the development of a methodology to predict fatigue life based on process monitoring. In addition, it will be investigated how the tailored stiffness of LPBF connection elements can be used to control the global load distribution within a structure. Throughout the project, the sustainability aspects of LPBF elements will be considered and quantified.
