Performance Evaluation of 3D Printed Metal Components Under Dynamic Load Conditions

Abstract

Additive manufacturing (AM) has significantly advanced the production of metal components, offering new possibilities for complex geometries and rapid prototyping. This paper investigates the performance of 3D-printed metal components under dynamic load conditions, including cyclic and impact loads. Using titanium alloy (Ti-6Al-4V), stainless steel (SS316L), and aluminum alloy (AlSi10Mg), components were fabricated using Selective Laser Melting (SLM) and Electron Beam Melting (EBM) techniques. Dynamic loading tests were conducted to assess fatigue resistance and impact performance. Results indicate that while titanium alloy components demonstrated robust performance under dynamic loads, stainless steel and aluminum alloys exhibited varying levels of fatigue resistance and impact resistance. Common failure modes such as delamination, warping, and material degradation were identified, impacting the overall reliability of 3D-printed parts. The study also explores optimization strategies, including process parameter adjustments and material composition modifications, to enhance the durability of 3D-printed metal components. These findings provide valuable insights into the suitability of AM technology for applications requiring dynamic load resistance and suggest directions for future research to improve performance and reliability in demanding environments.
