The advantages of additive manufacturing of metal components through laser powder bed fusion have been increasingly embraced across a variety of industries and applications. But, broader adoption of this manufacturing technology—especially for critical applications that require qualification and certification—increasingly require that computational models and in-situ monitoring of such processes be experimentally validated under highly controlled conditions with advanced metrology . This project seeks to develop research tools for measuring laser propagation to and from the laser-matter interaction, material cooling rates, and more, via high-speed micro-videography, radiometry, and other thermo-fluid non-contact—and contact—measurements [1, 2]. Desired qualifications for this postdoctoral position 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).
