Self-folding is a self-assembly strategy that induces folding of a desired 3D structure based on a predefined 2D sheet. Self-folding can be applied in the fields of actuation, sensing, and packaging. We use a desktop printer to define ink 'hinges' on sheets of pre-stressed polymer. The ink absorbs light to heat the polymer underneath and causes folding. We demonstrate origami folding and study various light sources to trigger the folding effectively and sequentially.
