A, B Zero-thickness 2D and 3D origami-kirigami patterns of regular triangular prisms, respectively. The blue solid lines represent mountain creases, the red dashed lines represent valley creases, and the green dotted line represents slit creases. C, D The 3D models of TPRTPS-1 and TPRTPS-2, respectively; E Ratio of change in volume of TPRTPSs. F, G The folding sequences of TPRTPS-1 and TPRTPS-2, respectively. H Ratio of change in surface area of TPRTPSs. I The folding sequence of a metal prototype of TPRTPS-2.
