Fig. 7: 3D print of a complex structure.

Cubic lattice structures were 3D printed using PBA-CTAs with various degree of polymerization (Xn): a Xn = 48; b Xn = 94; c Xn = 180; d computer aided design of lattice structure to be 3D printed; e Close-up view and f surface morphology of 3D printed strut-based lattice structure using PBA48-CTA. Materials were 3D printed using a molar ratio of [AA]/[PEGDA] = 4/1 at 28.2 wt% loading of PBA-CTA.
