Inspired by Heinz Isler’s hanging model, our group explored PET-G as a structural material. Using a vacuum machine, we heated 12x12-inch PET-G sheets at 180°F for 270 seconds, observing how gravity shaped them into parabolic forms. We systematically varied cutout patterns while maintaining consistent heating conditions. A laser-cut 1x1-inch grid helped track material stretch. Sheets without cuts formed sturdy parabolas, while cuts influenced final shapes—central cuts resulted in shallower forms, while others created diverse structures. Our controlled experimentation demonstrated how cut placement and size affect form, enhancing our understanding of efficient structural shaping through material behavior.
