Abstract

In-situ process monitoring in Electron Beam Melting (EBM) is critical in certifying build quality, by identifying contamination from the feedstock and condensate spallation from within the build area. The chamber condition in an EBM machine is different from a typical electron microscope. Therefore this study explores in-situ EBM material characterisation with a custom electronic imaging prototype. Typical contamination elements found in a popular EBM material (Ti-6Al-4V) were electronically imaged at room temperature. Material contrast is observed in the electronic images generated by the prototype. This trial is thought to serve as a baseline study for future EBM monitoring system development.
