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.

该博士项目的目标是解决围绕金属功能材料（FM）的知识差距，并建立多金属增材制造（AM）的新方法。这就需要确定激光增材制造的合适材料组合，并为不同材料之间形成的界面确定适当的设计准则。对于金属FM的成功，有一个关键需要了解如何不同的金属可以在AM组合，以实现所需的性能。为了实现这一目标，该项目将侧重于确定印刷组件界面区域的结构和热行为，其中不同材料接触。这将通过研究打印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（锐分布、扩散、互锁等）影响关节的坚固性。这些复杂部件的正确设计将需要表征和测试打印结构中形成的界面。
