Fig. 1 — Design and rationale of recyclable photocurable resin with superior mechanical and self-healing properties. (a) Illustration of the DLP 3D printing setup. (b) Schematic depicting the dynamic interaction between the stiff (4-acryloylmorpholine (ACMO) in orange) and compliant (monofunctional urethane (MUA) in blue, R₁ = (CH₂)_n, R₂ = (CH₂)_nCH₃, n = 2, 3, or 4) components via reversible hydrogen and ionic bonds resulting in both superior strength and self-healing within the printed composite. (c) (Left to right) Chiral, re-entrant, and honeycomb lattices printed using pure ACMO and ACMO-Zn-MUA resins. Scale bars are 1 cm.
