In a metal additive manufacturing (AM), or directed energy deposition (DED) process in this presentation, a laser beam is focused on a metallic substrate to create a melt pool; thus only a small heat-affected zone can be produced. Therefore there is a good opportunity to fabricate a structure with specified materials located in certain areas for multi-functional purposes. This type of structure with multiple materials is often called digital materials, as it is possible to fabricate a structure with materials specified digitally. The aim of this presentation is to discuss some current research efforts to achieve digital material fabrication using AM. One such digital material fabrication is Functional Gradient Material (FGM), garnering more and more attention. FGMs can be tailored to satisfy various property or functionality requirements as the user needs and working environments demand. To fabricate such FGMs, a metal AM process can be an effective processing technique so that customized compositions varying across the volume of the part can be achieved. This presentation will summarize the design and fabrication of digital material using the DED process. 

Learning Objectives:

  • Learn the benefits of digital material fabrication.
  • Understand the major challenges of digital material fabrication.
  • Use the concept for digital material design and fabrication.
