Description

Metal-based additive processes—especially laser powder bed fusion (LPBF)—are promising emerging manufacturing technologies for producing complex and highly-customized parts. These processes have been in development over the past 15+ years and their capabilities have grown significantly. An important effort within the LPBF community is the use of high-fidelity multiphysics models to predict melt pool properties, material cooling rates, material grain structure, and the mechanical properties of bulk parts. These models attempt to resolve a variety of complex physics that occur during laser-metal interaction, and the accuracy of such models must be validated by high-quality physical experiments. This project seeks to develop research tools for measuring laser propagation, material cooling rates, and more, through high-speed micro-videography, radiometry, and other thermo-fluid contact measurements. Desired qualifications include experimental research experience, design of mechanical parts and assemblies (SolidWorks experience is preferable), experience with developing VI’s in LabVIEW, and experience with data and image processing (MATLAB experience preferable).
