Abstract
This study is an experimental investigation to understand the electrical and mechanical properties of 3D-printed Polylactic Acid (PLA). These 3D-printed specimens will be printed layer by layer through the Finite Element Method. Quasistatic and Dynamic compression on the specimens will be tested and measured. Quasistatic compression will be tested using a Shimadzu AG-X, and Dynamic compression will come from the use of a Split Hopkinson Pressure Bar. Conductive PLA within each specimen will act as a strain gauge to measure the electrical response. This occurs simultaneously as the mechanical response is being measured. These experiments were performed at the University of Rhode Island in the Dynamic Photomechanics Laboratory (DPML). The results provided numerous data surrounding the electrical and mechanical response of PLA. It was determined that the strain gauge factor of the PLA specimens with a 12.954-mm by 7.874-mm dimension was 0.072 when dealing with quasistatic compression and 0.22 when dealing with dynamic compression.
