Exploring Sustainable Design with PETG Extrusion

This project utilizes PETG thermoplastic extrusion to pioneer innovative methods of reducing material usage while preserving the structural integrity of printed elements. By designing and fabricating lightweight, open-cell structures, the research investigates how deposition patterns, sequencing, and material properties synergize to optimize load distribution and stability.

A key objective is to address the pressing need for sustainable construction practices. By minimizing material consumption, the project reduces resource extraction, energy demands for manufacturing, and transportation impacts, significantly lowering environmental footprints. The choice of PETG, a recyclable thermoplastic, reinforces the project’s sustainability by enabling material reuse and reducing waste.

Through developing techniques that balance strength and efficiency, this work contributes to environmentally conscious design and fabrication practices, advancing the principles of a circular economy in modern construction.
