Cody Pack

Cody Pack is a Ph.D. candidate in the Department of Materials Science and Engineering at the University of Tennessee, Knoxville (UTK) working under the direction of Dr. Brett Compton. Mr. Pack received his B.S. in Chemistry from Lincoln Memorial University (LMU) in Harrogate, TN, where he performed research in polymer formulation. Prior to starting his graduate studies, he spent a year at Oak Ridge National Laboratory (ORNL) investigating the use and applications of strategic and critical materials in the National Stockpile.  In the fall of 2014, Mr. Pack received his Master of Science degree in Materials Science and Engineering with his thesis, Protective Coating of Titanium Diboride Reinforcement Particulates for Improvement of Titanium Metal Matrix Composite Armor Systems.

Mr. Pack’s current research lies in the area of 3D printing, for which he employs direct write (DW) additive manufacturing to investigate the application of novel architectures with various feedstock materials to create and characterize multi-material hybrid structures.In DW, a viscoelastic feedstock is deposited by extrusion through a small nozzle to build structural or functional components with complex geometry or compositional architecture. DW is compatible with a broad range of feedstock materials, provided certain rheological requirements are met. Because it directly deposits material only where desired, DW is ideally suited for printing multi-material composites and novel hybrid architectures where properties can be tailored in unique ways. Broadly, his research addresses issues of feedstock formulation, printing hardware design, printing process challenges, and sample production, testing, and analyses. More specifically, Mr. Pack’s current research involves application of a core-shell motif via DW withmaterial systems, such as a foam core-carbon fiber shell architecture for improved stiffness in cellular structures, a stainless-steel core-hydroxyapatite shell for biomedical applications, and a nickel core-titanium carbide shell for cermet wear applications.

In the past year, Mr. Pack was the recipient of two travel grant awards from the National Science Foundation to present his research at the joint POWDERMET/AMPM 2018 conference in San Antonio, TX, and at the Solid Freeform Fabrication (SFF) Symposium in Austin, TX. In past years, Mr. Pack served as a graduate teaching assistant for a senior-level course on biomaterials and the junior-level Principles of Materials Laboratory.During previous summers,Mr. Pack assisted with the Materials Teachers Camp and served as a mentor for local high school students attending the annual Materials Camp.
