History & Development

On March 16th, the Makerspace were contacted by Wisconsin-Madison University Hospital, to ask if they could make 1000 face shields. After an initial trip to Home Depot and craft stores that night to gather materials, a prototype was produced. Using samples of existing face shields from the hospital and training videos showing how all of the PPE works together, the Makerspace focused on creating a design that could be mass produced quickly, cheaply and be familiar to healthcare professionals.
