This thesis presents a set of fabrication techniques for upcycling HDPE (High Density PolyEthylene) plastic bags. It enables not only reusing abandoned plastic bags but also creating 3D objects by folding and joining newly-produced plastic sheets through fusion. Our fabrication techniques include both additive processes (global heat fusion, local heat fusion) and subtractive processes (cutting, scoring) to design and produce new plastic sheets and use them for a wide spectrum of personal fabrication. In this thesis, we also discuss the design factors that can be taken into consideration while using the proposed fabrication pipeline. We also present applications to demonstrate newly-enabled creative possibilities by the techniques we presented and how these fabrication techniques can be applied to personal fabrication. We also discuss the outcomes of a user study workshop conducted to evaluate these set of tools and techniques in the context of makerspaces.
