Hello, we are a team of five engineering students from WPI (Worcester Polytechnic Institute) that are working on a project for our engineering design class. The project was to design a manufacturable and effective head strap that holds a plastic face shield that can be used by those fighting COVID-19 on the front lines. This head strap is designed to be manufactured using a 3D printer.
WHAT :
Our design focused on protecting the user as much as possible while also limiting the amount of material and time it would take to produce on a 3D printer. We opted to have an upper shield that extends above the user's face to provide them better protection from airborne bacteria as a result of a cough or sneeze. We also designed the piece to be relatively thin to reduce production time as much as possible and to make it as flexible as possible without losing the integrity of the part. The double band in the front of the head strap allows for some distance between the face shield and the user's face. In addition, the multiple holes on the back allow for multiple different types and configurations of elastic straps to be used to secure the device to your head.
The 3D printer we used was a Sindoh 3DWOX DP200, with a build plate of 200 mm x 200 mm x 185 mm. The STL file, SOLIDWORKS file, and configuration file are all included in the zip folder.
