Photopolymerization has been widely used to create crosslinked photoset materials that have found wide applicability, including in 3D printing. Among the many chemistries available for these processes, those that leave residual surface functional groups provide avenues towards more advanced materials, including tunable surfaces and modified bulk physical properties, which may be further exploited by post-fabrication functionalization. Here, a comparison of polyester and polycarbonate photopolymers, which provide comparisons of thiol-ene and free radical crosslinking, are compared with regards to their thermo-solvation responsiveness, hydrophobicity, cellular interactions, and bulk properties. A focus is placed on leveraging such behavior in 3D, porous scaffolds primarily made with respect to the biomedical utility of the scaffods, their resultant physical behaviors, and the opportunities the chemistries provide towards material tunability.
