3D printing has enabled the unique combination of structures, geometries and functional properties otherwise unattainable via traditional manufacturing techniques, yet its adoption as a mainstream manufacturing platform for functional objects is hindered by the physical challenges in printing of multiple materials. Vat polymerization offers a polymer chemistry-based approach to generating smart objects, in which phase separation is controlled in order to achieve, at once, desirable chemical and functional properties of final 3D printed objects, and indeed direct-production of 3D printed smart objects. This study demonstrates how the spatial distribution of different material phases can be modulated by controlling the kinetics of gelation, polymer network density and material diffusivity through the judicious selection of photoresin components. A rich selection of morphologies and functional coatings are generated, illustrating a promising way forward in the integration of dissimilar materials in 3D printed smart or functional objects.
