Physical properties of UV resins used in this study. Physical properties of TPGDA and PPGDA resin are obtained from Ref. [16]. No viscosity data of these two resin solutions is available, and their viscosity is lower than PUA and MD 700 based on our observation during experiments. Physical properties of PUA and MD 700 are obtained from supplier’s MSDS.
