The intrinsic viscosity of the photo-curable monomer and polymer is measured to target the molecular weight of the material. The photo-curing polymer is produced through physical or chemical reaction, and the curing time and physical properties of the material are adjusted according to the purpose. It can be controlled the ratio of the photo initiator and urethane. For example, Thermoplastic polyurethane (TPU) series based on poly(tetramethylene glycol) (PTMG1000) as a polyol and methylene diphenyl diisocyanate (MDI) as a isocyanate were synthesized as a function of molecular weight formulation. After that, it is photo-cured by attaching acrylate, and it is designed by applying UV through hydrogel type 3D printing.
