Claim 0:
1. A three-dimensional (3D) printing method, comprising:
a resin providing step of providing dual cure resin;
a light curing step of irradiating the dual cure resin by an ultraviolet (UV) light to perform 3D printing, so as to form an intermediate body having a predetermined lattice shape;
a stretching step of applying a stress on the intermediate body in a stretching direction according to a stretching ratio of predetermined dimensions so as to stretch and form a stretched body; and
a thermal curing step of heating the stretched body to perform thermal curing and shaping so as to form a 3D printing formed body,
wherein, during the light curing step, a size of the intermediate body in a non-stretching direction is correspondingly pre-compensated based on the stretching ratio.
