n95 masks against coronavirus covid19 hackthepandemic nanoHack

Hospitales worldwide are on the verge of running out of N95 masks in the midst of the worst pandemic of the 21st century! Our purpose as a company has always been to make a positive impact and tackle global challenges through innovation, nanotechnology, and antimicrobial materials. Our purpose drives us to solve this problem in a cheap, fast, and decentralized way using #FabricaciónDistribuida. We propose a reusable, customizable, modular, antimicrobial, and antiviral respirator printed with high-quality copper nanoparticles. About NanoHack Our innovation is inspired by the most scarce product today: N95 masks. There's a shortage of these products worldwide, and they're a basic necessity, especially for healthcare workers who are at the forefront of fighting this disease. In many countries, authorities have also recommended using these masks (or similar ones) in public transportation. Despite being effective, these masks have some problems, such as a short lifespan (around 8 hours), and another major issue: respiratory viruses, particularly SARS-Cov-2 (COVID-19), can survive up to 72 hours on different surfaces. This is a problem because using a conventional mask would trap a high viral/bacterial load at less than a millimeter from our nose and mouth, exposing us even more to these dangerous microorganisms. NanoHack: The Open-Source Respirator NanoHack was inspired by a global pandemic. Radical innovations are born out of crises, so NanoHack is a unique design. Antimicrobial/Antiviral Made with PLACTIVE, an innovative nanocomposite developed with high-quality PLA and a patented nano-copper additive, scientifically validated and highly effective. Reusable/Recyclable You can use this mask whenever you want. The increasing use of single-use surgical masks and N95 respirators will have a negative impact on the environment. To prevent this negative impact in our environment, NanoHack will be made with recyclable material. Flat Pattern To facilitate manufacturing and transportation with massive shipments worldwide and to rural areas. Modular Filtration System The prolonged use of N95 respirators has demonstrated reduced lung capacity. These single-use respirators do not allow for regulation of air intake or particle size. NanoHack incorporates a modular filter disc that can effectively regulate air intake and particle size. This system can be customized using third-party filtration materials such as propylene non-woven, clothing, sponges, or different textiles to reduce the level of filtration. Assembly of NanoHack NanoHack was designed as a product that is printed in 3D on a flat plane and then assembled by each user with simple elements and procedures. Please follow the instructions for safe and correct use of NanoHack. 3D Printing Parameters Print the pieces with a 20% fill, without supports or rafts. Heat the NanoHack to 55-60°C with a hair dryer or hot water. The circular part must remain intact, so it's thicker to prevent deformation. When softened, join the nose wings and adjust wings located on the lower jaw. You can glue them for better fixation if you want. Reheat it and put it on your face for final adjustments. Make sure it's not too hot! If you feel any part of the mask doesn't fit well or is too tight, you can place a small piece of soft rubber in contact areas. Twist the "cap" with one or two additional filters. If using a filter, you can use a circular piece (simple or double) from a conventional mask (propylene non-woven) or add a round cotton face pad for makeup. Half of the pad can facilitate breathing.
