description abstract | A selffolding structure fabricated by additive manufacturing (AM) can be automatically folded into a demanding threedimensional (3D) shape by actuation mechanisms such as heating. However, 3D surfaces can only be fabricated by selffolding structures when they are flattenable. Most generally, designed parts are not flattenable. To address the problem, we develop a shape optimization method to modify a nonflattenable surface into flattenable. The shape optimization framework is equipped with topological operators for adding interior/boundary cuts to further improve the flattenability. When inserting cuts, selfintersection is locally prevented on the flattened twodimensional (2D) pieces. The total length of inserted cuts is also minimized to reduce artifacts on the finally folded 3D shape. | |
