WebJan 26, 2024 · Kirigami, a traditional paper cutting art, offers a promising strategy for 2D-to-3D shape morphing through cut-guided deformation. Here, authors report a simple … WebA particular kirigami two-dimensional (2D) precursor was then patterned onto the PET sheet via laser cutting. Then, the kirigami sheet was mounted onto a stainless steel cylinder with a radius of r 0 and heated in oven for 1 hour to form a kirigami cylindrical shell with a single principal curvature of κ 0 = 1/r 0 . This cylindrical curvature ...
