The huge run of protective masks are causing troubles for our health workers. To prevent to shortage of masks for hospitals caused by the public we want to offer some alternatives.
What it does
There already plenty of different designs for 3D printed open source protective masks. The 3D printed masks are an awesome idea to give the ordinary person an alternative to the medical masks but only if you have an 3D printer at home and some expertise. Knowing that the biggest part of the population does not own a 3D printer, the distribution and no access to good filter materials is the biggest issue. Since the Covid-19 outbreak our education institutions are closed with plenty of resources in machinery and knowledge. Our goal would be to use the 3d printers and injection molding tools of our education system to build these reusable masks and distribute them to the public.
How I built it
After test printing some open source models, we also built one our self with the focus of using common towels everybody have at home. Our model does not require a good printing quality since it is only one part. We decided that we want a model which can be used with normal towels and is only made of one 3d printed part.
Challenges I ran into
Building the filters with normal towels remains difficult. Using proper filtration material would be an solution since most designs with a 3d printed mask uses way less material as a normal mask.
What's next for 103 How to get local & reusable masks
We would like to talk with some of our professors if it would be possible to use our university location to 3d print or injection molding some masks. For the filters we would like to test some ordinary household products for filtering efficiency. To test the household products, we need a cooperation with a higher education institute or a testing place for safety masks. We also asking our local government Rapperswil-Jona for financial support to compensate the costs.
