Fig. 5From: Control of maleic acid-propylene diepoxide hydrogel for 3D printing application for flexible tissue engineering scaffold with high resolution by end capping and graft polymerizationA Optical images of the 3D printed scaffolds (10 layers) using the MPLE gels with three ratios of LP-capped gel: PEGDA (1:0.1, 1:0.2, and 1:0.3 w/v). B Microscope images of the 3D printed MPLE gel (1:0.3) scaffolds in lattice infill structure with 2, 4, and 6 layers by using different needle sizes (27G, 30G, and 32G). C Integrity factor (Ir) of three types of MPLE gels. D Pore factor (Pr) of the MPLE gel (1:0.3) scaffoldsBack to article page
