Abstract

This work provides a manufacturing strategy for the scaffold with heterogeneous mechanical properties via dual color tomographic volumetric printing (DCTVP). By initiating the polymerization of an acrylate and epoxy based multicomponent  material using visible (λ~455 nm) and UV (λ~365 nm) light in parallel, a composite scaffold with graded stiffness can be produced within several minutes. The stiffness contrast of printed samples is proved to be tuneable through adjusting the precursor composition. The achieved modulus contrast ratio between the UV and visible light cured samples ranges from 88% to 825%.
