This thesis examines the mechanical properties of an origami inspired structure and its equivalent cube counterpart to determine if this origami configuration is an effective load bearing and energy absorption structure. To test this, a folded paper model was created for visual realization and then 3D printed models were created to undergo compression testing using the Instron 4411. The data from testing was used to create stress-strain curves for each sample, which were then used to determine the maximum stress and toughness of each structure. The performance of these structures was also compared to other known material performance. The origami structure was found to outperform the equivalent cube in both maximum stress it could withstand before failure and toughness. These results are grounds for further research to be done to determine the validity of origami structures as viable alternatives to current material configurations.
