Directed Energy Deposition Analysis in Ansys Mechanical Software

Additive manufacturing (3D printing) can be a cost-effective way of producing parts, especially when making use of the design freedoms the manufacturing process enables, such as topological complexity and the ability to print assemblies in one step. In a directed energy process (DED)—also known as laser engineered net shaping (LENS), electron beam additive manufacturing (EBAM®), wire arc additive manufacturing (WAAM), or laser deposition technology (LDT)—a laser or electron beam creates a melt pool on previously solidified material where blown powder or fed wire is introduced to add material.

This course introduces you to DED Process simulation within Ansys Mechanical™ structural finite element analysis software, which simulates the DED printing process at a macro-/part-scale level and provides insights into the thermo-mechanical performance of the part and print under prescribed printing conditions.

Learning Outcomes:

Following completion of this course, you will be able to:

• • Understand the DED wizard.
  • Set up simulations for DED processes.
  • Predict parts out-of-tolerance deformations and hotspot areas.
  • Conduct basic optimization of process parameters.
  • Understand the different clustering methods available for DED.
  • Conduct 3-axis and multi-axis DED simulations.
