Continuing our experiment with PET-G, we developed a membrane grid system to explore the behavior of the PET-G under applied tension. A key feature of our setup was having an embroidery mesh as both a template and structural frame. To manipulate the plastic's deformation, we threaded string through 1x1 inch grid intervals in the mesh, forming a suspended network of tension points beneath the PET-G sheet. By carefully adjusting the position and tautness of these threads, we created varying patterns that introduced localized resistance. This allowed us to control how and where the plastic would deform when subjected to heat and gravity.
