| Abstract Scope |
Direct ink writing (DIW) is relatively unique among common AM techniques in that it can use precursors that are liquid at room temperature. This allows processing of thermosetting polymers that would normally be difficult to print. However, very specific rheological properties are required for printing. To obtain these, solid additives are used to affect the rheology of the resin. The overarching goal of this project is to develop a thermosetting polymer ink suitable for DIW. This project specifically focuses on characterizing the change in rheological properties of the resin after the addition of solid nanoparticles. Changes in loading fraction, the addition of curing agents, and the presence of multiple nanoparticles and their effects on the rheology of the epoxy will be explored. The data indicates all three parameters have significant impact on the properties of the epoxy. These lessons will be used to construct a suitable ink in the future. |
