NASCAR is stepping up to help the fight against COVID-19 by producing face shields for health care workers. Engineers are using five 3-D printers as NASCAR's Research & Technology center to make the shields, running the machines up to 18 hours a day to print as many as possible.The five 3D printers at NASCAR's Research & Technology center are typically producing composite parts. After races were halted March 13th, NASCAR engineers wondered if the printers could be used in the fight against COVID-19, specifically to ease the shortage of personal protective equipment for health care workers. They contacted suppliers and came up with designs for face shields the printers could make. NASCAR is donating the shields as a part of the yearly charitable community acts series.
