A 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 study
