My name is John Cordonier and I am from Parkersburg, West Virginia. I graduated from WVU with a bachelor’s degree in chemical engineering in May of 2014 and joined Dr. Bhattacharyya’s research group in May of 2015. I have done work in the additive manufacturing field on a controls system for a nozzle-based robotic arm that prints polymeric fluid and on modeling the 3D printer using COMSOL Multiphysics software.

Modeling and Simulation of a Direct-Write Manufacturing Process
In this project, direct writing of an ink composed of a conductive material dispersed in a polymer medium is used to create conductive pathways for use in flexible electronic devices. To develop an efficient controls system, the parameters that affect the printed fluid must first be understood. The pattern geometry and dimensions created by the direct writing method mainly depend on three main factors: the properties of the ink, the parameters used in the operation of the direct-writing machine, and the ink-substrate interaction. In this work, a detailed model of the direct-write process is developed in COMSOL. While this model provides detailed information and very high resolution, the model is computationally expensive and is not suitable for control applications. A simple model suitable for real time simulation is developed in MATLAB. The effect of different operating conditions is studied. A control strategy is developed for efficient regulation of the track dimensions.
