Near-Void-Free 3D Printing

In recent years, metal additive manufacturing has emerged as a transformative technology, impacting traditional manufacturing processes across industries. Its ability to create complex geometries and customized parts with unprecedented precision has propelled it to the forefront of innovation in engineering and design. However, when compared to traditional manufacturing techniques, materials produced through 3D printing often exhibit inferior fatigue properties under cyclic loading conditions. This discrepancy significantly limits their widespread application as structural load-bearing components. The challenge lies in addressing the poor fatigue properties commonly attributed to the presence of micro voids induced during the current printing process procedures. Improving the fatigue performance of 3D printed materials and components has thus become a crucial research focus.
