3D printing had been originally known as a rapid prototyping tool since its advent in 1980’s until advanced processes (high resolution, large size, high throughput, etc.) and materials (metals, ceramics, composites, etc.) for various applications were developed. Use of 3D printing technology has spread gradually into many industries as well as education and research during the last three decades. This talk includes a brief history of 3D printing and state of the art. In particular, 3D printing of smart materials for tactile sensors will be highlighted. Although 3D printing technologies are mature enough in terms of creating 3D structures, there is lack in creating 3D smart structures including sensors, actuators, and electronics. Recently, the speaker’s group at The University of Akron successfully developed stretchable tactile sensors using a customized 3D printing process called direct-print photopolymerization (DPP) and printable polymer/nanocomposites. Previous studies proved advances in the design and development of flexible and integrated tactile sensors, however there still remain many limitations for their usage in real applications. In addition, these sensors are usually a sheet form, and thus they do not have three-dimensionality required in a freeform body component, which could be used in wearable electronics. In this talk, the speaker will address current state of the art and challenges involved in materials, processes, and applications. At the end of seminar, the speaker will introduce other 3D printing processes and materials if time is allowable. |
