Abstract:
A 3D printing method including: obtaining a wavelength-absorptivity relationship of a liquid forming material (R1), where the wavelength-absorptivity relationship includes absorptivity peaks (P1, P2, P3) of at least two corresponding wavelengths; forming a 3D object by using a 3D printing apparatus (100), where the 3D printing apparatus provides a first light (L1) to cure the liquid forming material layer-by-layer and stacks the same to form the 3D object, and a wavelength of the first light is one of the at least two corresponding wavelengths; and providing a second light by a post curing device (200) to irradiate the 3D object, where the second light (L2) comprises the at least two corresponding wavelengths.
