In this project, we explore a different approach to layer manufacturing, namely, a layered manufacturing product that, while using a single material, produces an entity of varying material properties. Materials testing of PMC®-724 demonstrate the material's capacity to possess a range of Shore A Hardness over a range of elasticity, illustrating the potential for printing with variable property materials. Moreover, we will also explore a new approach to fabrication that challenges the concept of Computer- Aided Manufacturing (CAM) by introducing a software application that, rather than providing a means of digitizing the geometry of a completed design, allows engineers and designers to create and design structures that are defined at various points by their material behavior as opposed to their geometry. As a proof of concept demonstration, a mono-material, variable property shoe sole will be printed using property-mapped polyurethane elastomer PMC®-724 with the new software.","abstract_html":"Since its introduction in the late 1980s, layered manufacturing has become an increasingly efficient and common means to delivering functional and visually representative prototypes in relatively short amounts of time from previously prepared Computer-Aided Design files.
