3D printers technology used in ventilators

My self Athul kumar a this is about how a 3D printing technology helped in preparing a ventilator which does not requires electricity to operate  this was made possible during the COVID-19 pandemic which can also enable the hospital to manufacture the parts they require inside the hospital itself which can reduce their cost even more so this is how it works Limbitless used printers in its lab at UCF to print the pieces necessary for high quality prints and large-scale distribution. Limbitless key engineers and co-founders, Dominique Courbin '18 and John Sparkman '13 '15, optimized the production of the critical pieces at UCF. The pieces fit perfectly when assembled at OHSU. The coordination between the two teams was critical to rapidly prototype the design,Depending on the printer used, a single ventilator could be manufactured within three to eight hours and made operational with the addition of low-cost springs available at any hardware store. The low-tech ventilators can be replicated anywhere in the world for less than $10 of material.So for the testing Chi and his team assembled the first prototype and placed it on an oxygen tank to test it. The goal was to see if it would work for at least 24 hours without any durability issues. Chi's team had already performed extensive modeling and testing in the lab, but the next 24 hours were to determine if OHSU would go after FDA emergency approval.On April 24, Chi filed with the FDA because the ventilator was still pumping air with no issues 120 hours later.So this method got approved and it would not only help hospitals now, but in the future. The ventilators could be used during another pandemic or in remote regions or after a natural disaster when electricity is scarce.
