DIW printing of LAL polymers to produce highly deformable 3D structures. (a) Stress–strain behavior of 3D printed and molded tensile bars of LAL polymers tested at room temperature and 0.01/s strain rate. (b) Photos of honeycomb (upper) and gyroid (lower) structures printed using an LAL polymer (f = 31%, λ = 0.25%). The light yellowish color is attributed to reprocessing of the polymers at high temperatures and contamination by the extruder. Scale bars: 5 mm. (c) Compression stress–strain behavior of the 3D printed gyroid in (b). The compression strain rate is 0.003/s. Inset: cyclic compression–release profile exhibits a hysteresis for the deformation of 20%. Error bar: standard deviation for n = 4. (d) Ashby-type plot comparing elastomers for solvent-free DIW printing based on tensile breaking strain and Young’s modulus. Filled green circles: our modular soft elastomers; other symbols: literature data (Table S2).
