Abstract
By locally engineering material compositions alongside internal and surface structures, we can create objects with enhanced or even entirely new functionalities that surpass those of homogeneous parts. These functionalities may include pre-programmed capabilities such as sensing, bio-screening, and fluid manipulation, as well as programmable functions like robotic operations. However, fabricating heterogeneous objects with precise functionalities directly from digital models presents significant challenges in design, modeling, and process planning.
In this talk, I will share our recent advancements in overcoming these challenges through novel acoustic field-assisted manufacturing techniques. Specifically, I will introduce our work on integrating acoustic fields into photopolymerization processes, enabling the production of functional particle-polymer objects with hierarchical surface structures and spatially varied material compositions. I will discuss key aspects of materials and geometric design, process modeling, and planning strategies, along with the resulting material properties and functionalities. Applications in soft robotics, microfluidics, biomedical devices, and energy management will be highlighted. I will also briefly introduce our newly launched NASA MIRO Center for In-Space Manufacturing at UIC at the end of my talk.
