Fig. 1From: 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 Probable chemical schematic of the MPLE printing gel synthesis by the condensation polymerization of maleic acid, propylene oxide diacrylate and lipoic acid in a pot (i.e. the LP-capping gel) and then radical graft-polymerization of PEGDA during 3D printing. The 1(the LP-capped gel):0.3(PEGDA) ratio was chosen for the optimal results for 3D printing in this studyBack to article page
