Abstract Scope |
Polymeric photosets for 3D printing processes are one of the largest growing material classes globally, but the limited material library and functionality are consistent problems that limit expansion into industrial applications. Here, we leverage ring opening polymerization to produce low viscosity Newtonian photopolymer resins suitable for digital light processing (DLP) 3D printing. Through the use of compositing and simple organic modifications of the polymers, rheological and other physical properties of the photosets may be tuned towards transferring the resins into shear thinning inks for direct ink writing 3D printing. The balance of rheological properties with reactivity is also discussed, highlighting how the balance of properties may be leveraged for different impacts on layer integration, solidification, and part resolution. Ultimately, this design process may be further leveraged to enhance or install different functionalities including conductivity, photoresponsiveness, shape memory, and even degradability. |
