At a pace of eight halos per hour, more than 850 face shields specifically designed for classroom instructors have been 3D printed in Van Pelt and Opie Library.
Headset compatible, adjustable and designed to direct exhalations behind instructors rather than toward students, the shields can be worn during lectures as part of Michigan Tech’s face covering requirement, effective inside all buildings and anytime six-foot physical distancing isn’t possible outdoors. The shields are based on an open-source design produced for local health care workers and first responders shortly after the pandemic began. Since then, the design has been modified several times based on faculty research and feedback. In addition to the primary consideration — the shield’s ability to redirect projected respiratory droplets — tweaks include features that enhance fit and comfort, accommodate headsets, reduce glare and improve both flexibility and strength.
“This is still an evolving design as we move ahead,” said David Holden, the library’s manager of technology and innovation and one of the masterminds behind the 3D PPE project ongoing in the library since spring 2020.
From physics (droplet measurement) to visual and performing arts (acoustics testing), departments across campus are contributing to the project. Watch the video to see how the project came together — and what’s next:
Michigan Technological University is a public research university founded in 1885 in Houghton, Michigan, and is home to more than 7,000 students from 55 countries around the world. Consistently ranked among the best universities in the country for return on investment, Michigan’s flagship technological university offers more than 120 undergraduate and graduate degree programs in science and technology, engineering, computing, forestry, business and economics, health professions, humanities, mathematics, social sciences, and the arts. The rural campus is situated just miles from Lake Superior in Michigan's Upper Peninsula, offering year-round opportunities for outdoor adventure.
