The development of biobased photopolymerizable resin systems containing thermochromic material (PCDA) for digital light processing (DLP) 3D printing has been investigated. Biobased acrylated monomers were formulated with a photoinitiator, and the effects of PCDA content on rheological behavior, photopolymerization characteristics, and thermomechanical properties were evaluated. Rheological measurements revealed that the viscosity and shear-thinning behavior of the formulations were significantly influenced by the addition of PCDA, which is a key factor for printability in DLP processes. The curing behavior and conversion were examined to assess the influence of PCDA on photopolymerization. Thermal properties of the cured materials were characterized by DSC and DMTA, indicating that the incorporation of PCDA slightly modified the glass transition behavior and viscoelastic properties of the polymer network.
