| Abstract Scope |
Additive manufacturing has moved from a prototyping technique to a means of producing actual-use components including high-temperature-and-pressure applications i.e., heat exchangers and solar receivers. However, fabricating these complex geometries without process optimization can cause premature failure due to defects and dimensional inaccuracy, especially when we attempt to fabricate them in multiple systems. In this research, we demonstrate an experimental pipeline for qualifying an LPBF system and optimizing the process to fabricate complex geometries without compromising properties such as creep and fatigue. We discuss not only fabricating the co-designed (i.e., designed to meet LPBF constraints) heat exchangers and solar receivers with high density, dimensional accuracy, and reproducibility but also quantifying the uncertainty associated with printing in different LPBF systems. We address the variations of the microstructure in the printed specimens to probe the variations in the mechanical properties, consequently demonstrating the successful fabrication of robust solar receivers among multiple LPBF systems. |
