Wavelength-selective polymerization processes manipulating polymer sizes, compositions, or architectures offer significant opportunities in the advancement of photopolymer fabrication approaches, including for photoresists and stereolithography. One common strategy toward wavelength controlled polymer properties is reliant on strict manipulation of orthogonal polymerization systems, which can result in bulk inhomogeneities and residual monomers within the polymer matrix. In this work, a novel approach toward wavelength controlled properties using UV and visible light is presented. In this system, the degree of cross-link density is controlled within one polymerization manifold, realizing spatial control over polymer thermal and mechanical polymer properties.<br/>
