Hong Kong makers fought COVID-19 with 3D printed filtering systems for 3M masks AM Industry
Hong Kong was one of the first regions to get hit by the COVID-19 outbreak and also one of the first to effectively reduce the rate of contagion. 3dpbm reported early on about local firms 3D printing face shields for healthcare workers. Now a number of other maker projects (and videos) have emerged that can provide some valuable lessons for printing filtration adapters to use on standard 3M masks to protect against coronavirus. Disposable surgical masks had been in shortage since late January, so Hong Kong makers come up with various 3D printable designs to adapt a 3M half mask to extend the number of times it can be reused [STLs available here]
