65 - Review on in-situ thermal monitoring during direct energy deposition: methods, principles and applications
Abstract
Direct Energy Deposition (DED) technologies have undergone extensive research and investigation, finding applications across various industries such as medical, automotive, aerospace, tooling, and remanufacturing. Still, the quality and repeatability of the components and parts produced by this process do not fully meet all requirements of the industrial applications and hinder further process development. A better understanding of thermal phenomena involved in DED processes is of paramount importance in order to glean valuable insight into the fabrication of high-quality products. This study introduces a variety of techniques for conducting in-situ temperature measurements during DED process and discusses their applicability for investigating specific thermal phenomena. It offers a comprehensive description of the fundamental principles underlying these techniques and illustrates their practical application with examples drawn from the existing literature. The latest developments of a methodology for monitoring the molten zone temperature using a high-speed camera are presented. This methodology has proven to be a valuable tool to provide diverse information, including the evolution in dimensions and temperature distribution of the molten zones throughout the process. Finally, the study concludes by offering guidelines to aid in the selection of suitable instruments tailored to the specific phenomena of interest in DED, providing valuable insights for future research.
