Intrinsic mechanical properties of PGSA made by different exposure times (x-axis) and PEGDA concentrations (filled pattern): (A) Tensile modulus, (B) Ultimate tensile strength, and (C) Failure strain. (D) Example stress-strain curves of tensile tests on samples printed with HiResin (10% PEGDA) with different light exposure times. The tensile modulus was calculated by the slope of the linear region of the stress-strain curve. The ultimate tensile strength was the highest stress the sample reached, and the failure strain was the largest strain the sample achieved before failure.
