The objective of this PhD project is to address the knowledge gap around metallic Functional Material's (FMs) and establish new methods for multi-metal Additive Manufacturing (AM). This requires the identification of suitable material combinations for laser-based AM and the determination of appropriate design guidelines for the interfaces formed between dissimilar materials. For the success of metallic FM, there is a critical need to understand how different metals can be combined in AM to achieve desired properties. To achieve this, the project will focus on determining the structural and thermal behaviour of the interface regions of the printed component, where dissimilar materials are in contact. This will be done by studying the printing laser parameters' effect on these regions. Similarly, it is essential to understand how different material distributions at the interface (sharp distribution, diffused, interlocked, etc.) affect the robustness of the joint. The correct design of these complex parts will require characterizing and testing the interfaces formed in the printed structures.

该博士项目的目的是解决围绕金属功能材料（FM）的知识差距，并为多金属增材制造（AM）建立新方法。这需要确定基于激光的AM的合适材料组合，并确定与不同材料之间形成的接口的适当设计指南。为了获得金属FM的成功，迫切需要了解如何在AM中组合不同的金属以实现所需的特性。为了实现这一目标，该项目将集中于确定印刷成分的界面区域的结构和热行为，其中有相似的材料接触。这将通过研究印刷激光参数对这些区域的影响来完成。同样，必须了解界面处的不同材料分布如何（尖锐的分布，扩散，互锁等）影响关节的鲁棒性。这些复杂零件的正确设计将需要表征和测试印刷结构中形成的界面。
