Ultrasonic Group Member
Air leak rates of 3D printed parts were investigated. Various polymer printing techniques, such as FDM and SLA, were investigated as a rapid manufacturing technique for ventilator parts in short supply. Parts were printed and their air leak rate was studied.
Jeff Ellis is a member of the ultrasonics group at EWI. He is responsible for steering EWI’s plastics technology roadmap, developing strategies for external engagements, innovating new plastics technologies through internal research and development, and ensuring high technical quality of proposals and reports for customer projects. Jeff has been studying the interactions of polymeric materials with their surrounding environment since 2004. Since 2013, his focus has been using process, structure, and exposure properties to determine root cause failures of polymeric medical devices. During this time, he has consulted for many Fortune 500 companies in consumer products, health care, military, and automotive, among other markets. Jeff’s work has been implemented in all phases of the product development cycle, from ideation of a new product to failure analysis of an existing product. Many of these projects utilized his expertise in polymer processing, selection, failure analysis, testing, degradation, and aging. With this experience, Jeff has been able to help clients develop and produce a wide range of robust and reliable products. Prior to joining EWI in 2020, Jeff worked at Battelle for 11 years, most recently as Senior Research Scientist in the Advanced Materials group. In this position, he performed the duties of client relationship manager, proposal author, principal investigator, report author, and technical reviewer. Jeff has been published in multiple technical journals and holds several patents.
