In order to provide confidence in laser-based directed energy deposition (DED) processes, in-process monitoring can be utilized. Dynamic layer selection technology enables scanning each layer of the build process to monitor build quality and accuracy in real-time, creating a topographical map of each layer as the part builds up. Using the data provided from the scan, closed-loop control can be enabled to auto-correct errors to achieve a part that is free of defects. This presentation will include a brief overview of the DED process, preliminary results from integrating dynamic layer selection into the process, and provide a step-by-step demonstration via video of how the technology is used.
- Describe the directed energy deposition process and associated challenges
- Explain how in-process monitoring can be utilized to improve build outcomes
- Determine the feasibility of implementing in-process monitoring capabilities into other process and applications
Why Is It Important?
As metal additive manufacturing adoption continues to expand from prototyping and demonstrator components to production components, quality parts and part-to-part replication become necessity. The ability to monitor and adjust the process during the build is one approach to providing the insight and confidence required for production parts.
