Logan received his PhD from the University of Tennessee – Knoxville (UTK) in mechanical engineering. His doctoral research centered on increasing the capabilities of WAAM to deposit large overhangs for complex geometry by developing custom trajectory planning strategies to influence non-gravity-aligned bead geometry. While at UTK, he also developed sensing and controls for the Tracking Fluroscope System (TFS), a custom-designed research robot sensing array designed to take non-invasive fluoroscopy of patients with knee replacements.
Logan was also involved with research at the Manufacturing Demonstration Facility (MDF), part of Oak Ridge National Labs (ORNL) where he worked on a variety of projects including in-situ monitoring, data correlation for Laser Powder Bed Fusion (L-PBF), and large scale WAAM. While there, he integrated his PhD work for trajectory planning techniques with the metal Big Area Additive Manufacturing (mBAAM) group at the MDF.
Logan currently works in the arc welding and DED processes group at EWI on wire and arc additive manufacturing (WAAM) using a variety of welding processes including plasma arc welding (PAW) and gas metal arc welding (GMAW). He performs DED in all of EWI’s robotic cells and also applies his experience in robotics, sensing, and controls to EWI’s automation projects.
