Congratulations to Nathan Hryniewicz on Presenting His Research at IMECE 2025

We’re happy to share that Nathan Hryniewicz recently gave a talk at the International Mechanical Engineering Congress & Exposition (IMECE), held in Memphis, Tennessee, from November 16 to 20, 2025.

His presentation was based on the paper titled “Optimizing the tribological properties of 3D-Printed PETG/PTFE Composites,” aimed to improve the efficiency and performance of 3D-Printed dynamic end-use parts, such as joint prostheses or robotic end-effectors. To do this, he investigated a material novel to FDM 3D-Printing, a composite of 90% PETG and 10% PTFE, with the intention that the PTFE would lend its self-lubricating properties to reduce the COF in the final part. He also investigated the effect of two FDM process parameters, raster width and wall count, on the COF with the goal of being able to fine-tune tribological and mechanical properties. The overarching goal of his paper and the surrounding field is to push the limits of the FDM manufacturing method as a whole, in order to broaden its applications.

Nathan Hryniewicz is a senior high school student at Newark Charter School in Newark, Delaware, who joined the Carpick Lab during the summers of 2024 and 2025 as an intern. He has been a talented and dedicated intern, focusing on modifying friction-testing instruments and helping enable the characterization of nanoparticle additives in grease.
