Abstract
This research explores the use of different metals combined through 3D-printing to enhance the performance of materials, with a focus on making heat exchangers more cost-effective for renewable energy. The goal is to replace a costly high-temperature alloy with a more affordable low-temperature alloy, using metal additive manufacturing for its benefits such as less material waste, faster production, reduced weight, and the ability to print entire assemblies in one go. The study delves into a unique combination of two 3D-printing techniques, Directed Energy Deposition and Laser Powder-Bed Fusion, to create a multi-material composed of stainless steel 316L and a nickel-based superalloy, Inconel 625. The primary focus is on understanding the structure and properties of this material, documenting mechanical properties, and characterizing its microstructure. By investigating how these additive manufacturing techniques influence the material's structure and properties, the research provides valuable insights on the fabrication of multi-materials. It expands our understanding of how combining different 3D-printing methods can enhance the production of multi-material components.
