We are currently living through an unprecedented global pandemic that has affected every single aspect of our lives. Whether it is staying six feet apart from your friends, mask-wearing at malls, or trying to learn over Zoom, everything has changed. While several problems have arisen due to the pandemic, it is important to note that there have also been several solutions. One of the most effective ways engineers have faced the challenges posed by the pandemic is through the use of 3D printers.

In the early stages of the pandemic, there was a large shortage of PPE or Personal Protection Equipment. Everyone rushed to the stores to buy masks and gloves, and this sudden increase in demand created a shortage that negatively affected hospitals and other front line workers. Many large businesses helped these hospitals by 3D printing facial shields for healthcare workers to use. 3D printers were first created in 1983 and quickly rose in popularity in the late 200s as they become more affordable. 3D printers are kind of similar to regular printers in the way they operate. They build up a 3D model of whatever they are printing, working from the bottom up one layer at a time. Instead of using ink like a regular printer does, 3D printers use layers of molten plastic or powder and fuse all of the layers together to create a solid structure. Companies use 3D printers to prototype models and even 3D print organs, but they began using these incredible inventions to create facial shields and donated them to hospitals.

COVID-19 is unlike anything our world has seen before and the impact of the pandemic is vast. However, there are engineering solutions that can lessen the negative impacts of this virus. By repurposing existing technology, companies were able to help those in need and 3D print facial shields so doctors and healthcare workers can keep on helping others.
