Biomass-derived monomers are used to produce photo- and functional 3D printable materials. Ring opening polymerizations are used to incorporate bioderived monomers, such as limonene oxide, into photopolymers where linkages are tailored to control physical properties. Reactive diluents are synthesized from functional biomass such as terpenes and terpenoids. Structure-property relationships are explored by varying diluent concentration, photopolymer species, and processing behaviors using 3D printed scaffolds. Importantly, bioderived content and degradability/recyclability are assessed for the formulations, providing a life-cycle comparison of the formulations to ascertain greener alternatives to conventional 3D printing polymers.
