Representative photos of printed cylinders using resins with 2.5% (upper) and 0.3% (lower) crosslinkers. The elastomer with 2.5% crosslinker fractures at 50% compressive strain, while the elastomer with 0.3% crosslinker can be compressed to 80% strain without fracture. (b) Compressive stress-strain curves of printed cylinders with various crosslinker concentrations. Inset: Zoom-in of the compressive stress-strain curves at small strains. ).
