N95 Masks versus 3D Printing
Many of us hadn’t even heard of the N95 masks before the coronavirus pandemic occurred. However, these masks have now become common in every household. While a major part of the world is facing a shortage of these masks, 3D printers have joined us in fighting against COVID-19 and we now actually have 3D printed N95 masks! However, the big question is, are they practical?
The Downside:
The 3D printing process builds a three-dimensional object from a digital file, by successively adding filament, layer by layer. While it is quite reliable, 3D printers don’t always deliver first-class results. 3D-printed items sometimes fluctuate in dimensions and result in some level of design noise. Regardless of whether the printed material is perfect or not, the surface of the mask may or may not adapt to the user’s face and may cause a shortage of the exhalation of carbon dioxide. Even if the mask were worn for only a short period, the carbon dioxide collected is quite a risk for the user, as he/she may suffer from faintness and intoxication, which will eventually lead to death. Wearing tight N95 masks for long periods, in general, may also cause bruises on one’s face.
How could we replace these?
These aren’t the only 3D printed masks that have caught public attention. The best is the 3D printed face shield. Many of these masks are made up of a special polymer that repels viruses and bacteria. They cover your eyes, nose and mouth — basically your entire face. We can also 3D print buckles that make face masks less painful to wear. Small bars on either side of the plastic buckle hold the elastic taut behind the user’s head so that it doesn’t put painful pressure on their ears. When wearing a mask, the elastic bands are looped around the notches on either side of the guard; this ensures that they stay in place while not rubbing the back of the ears.
However, the best way to control all of this is to stay at home and avoid going outside. Remember … we are all in this together. Let’s stand strong and fight against COVID-19!
