Abstract Scope |
Direct ink write AM of sub-millimeter diameter thixotropic elastomer struts is discussed. These thin strut films have use cases in applications such as soft robotics and flexible electronics. Consistent dimensional properties are important to ensure performance repeatability for high precision applications. The design features that are analyzed for quality are strut diameter and hatch spacing. Thin strut quality is measured using optical microscopy. Tool feed rate, material deposition rate, and deposition nozzle diameter are shown to each have an effect on thin strut quality. Experimental results for optimal process parameters for production of thin silicone elastomer struts are reported. |
