Abstract: Chemical composition of a component fabricated using high energy density input based three-dimensional additive manufacturing is in-situ monitored in real time. Laser Energy Assisted Breakdown Spectroscopy (LEABS) is coupled with a rapid physics-informed peak identification algorithm (RPIPIA) to monitor the atomic composition of component material (metallic, intermetallic, ceramic and metallic or ceramic matrix composites) in pseudo-real time during its fabrication using high energy density (laser, ion beam, gas plasma, electric resistance/discharge, gas torch) input (HEDI) based additive manufacturing.
