Abstract
Description
In response to the fight against COVID-19, TUCAT, a transdisciplinary team at Temple University, has created a Cast Assembly & User Manual that describes the tools, materials, and processes required for the mass production of the resin cast face shield. The face shield consists of 5 elements: shield frame (cast resin), three hole punched clear plastic shield, top foam protective insert (optional), 3D printed elastic adjustment clip (optional), and elastic strap. This manual is accompanied by five supplemental files that contain the designs for these materials. Unlike 3D printed face shield frame designs which are straight forward but slow in production, this process requires the creation of reusable positive and negative molds at the beginning which allow for the rapid production of large numbers of repetitive parts per hour. As the most complex aspect of the design is the casting process developed for the shield frame, most of this document will be dedicated to these processes. All components in this face shield are interchangeable and reusable. Additionally, all components are pressure fit. No fasteners or adhesives are necessary.
