WHY :
We are a group of four engineering students at WPI (Worcester Polytechnic Institute) taking the class Introduction to Engineering Design. For this class, we were given the assignment to design a face shield that could be 3D printed to be used during the current COVID-19 crisis.
WHAT :
This design is meant to maximize safety while requiring few parts. It fits the shape of the head and is able to be worn on its own (without an elastic). We thought it would be more convenient if a band wasn’t required to hold the face shield since there is a possibility of losing the band or breaking it; however, there are still hooks in the back where a band can go for a more secure fit. We also used hooks on the front of the design for the face shield attachment instead of pegs so the attachment doesn’t risk falling off. We also included a vertical shield to keep particles from going over the shield. Other designs feature a slanted shield, but we decided to have the shield come straight up from the band in order to cut down on print time and save material. This is not much different from the other design and it still blocks particles from going in above the face shield attachment. In addition, due to its simple design, it does not have many tight crevices and can be easily disinfected.
This design was 3D printed out of PLA on a Sindoh 3DWOX DP200 3D Printer with a base plate size of 200mm by 200mm. Attached in a Microsoft Word Document are the printer settings used. Both the Solidworks file and the STL file are attached.
