While progress has been made in customizing the shape of material goods through advanced manufacturing processes, customizing the properties of the materials is still a slow development process. A major factor slowing materials customization is understanding the interactions between components in the complex mixtures used to make functional products and, especially, how those interactions impact manufacturability. Our research approach integrates materials, rheology and processing to enable new manufacturing innovation practices that integrate the materials needed for manufacturability early in a product design process. The link between materials and rheology is frequently studied, but is complex due to the prevalence of multicomponent mixtures. The link between rheology and processing is standard for polymer manufacturing, but research engineers cannot pull a “rheology” off of a shelf, they must select a set of chemicals. Thus, to meaningfully decrease time to production, a faster link between materials and processing for complex mixtures must be made. Specific advances in tying solution properties to electrospinability via extensional rheology and tying particle and polymer properties in a high solids suspension to direct ink write printability through shear rheology will be discussed. This work provides the foundation to decrease the time to production for commercial products and enable customization of materials by integrating formulation for processing into early stages of development using fundamental chemistry-processing relationships.
