Abstract Scope |
Additive manufacturing of components via Directed Energy Deposition (DED) is a complex process involving melt pool dynamics, high cooling rates, power fluctuation, changes in feedstock flow, gas flow, etc. contributing to process instability and failed parts. It has been recognized that in-situ monitoring can be used to measure and control the bead shape, hence build geometry, helping save significant time and money by reducing part failures.
Addiguru in collaboration with the University of Tennessee, Knoxville demonstrated the feasibility to fuse data from Short Wave Infrared (SWIR) and Long Wave Infrared (LWIR) cameras for measurement and control of bead shape.
A dependency on bead size and inter-layer temperature (ILT) was observed. An experiment showed that the bead size or shape can be controlled in real-time to reduce issues that cause process instability and part failure. |
