COVID-19: Personal protective equipment half-mask with an P3 exchangeable external filter made with 3D printing technology offered for a free-licence for a non-commercial usage

The Czech start-up has developed a personal protective device - a half-mask - with an exchangeable FFP3 filter that meets the highest degree of protection. While a mask usually covers whole face, the half-mask covers only mouth and nose. The set consists of the body of the half-mask, designed for exclusive printing on Hewlett-Packard MultiJet Fusion 3D machines - 4200 and 5200 series, and an external filter certified according to the EN 140:1999 norm and therefore meets the same or higher degree of protection as a FFP3 respirator. The half-mask is neither prepared nor certified for printing on other 3D printers including 3D home printers. The selected technology guarantees optimal features such as flexibility, low weight and impermeability but also biocompatibility. Selected specifications: - Durable material: Polyamide + Thermoplastic polyurethane (face sealing) – storage period >10 years - Filter – Filtration efficiency: 1 - 10–4% (0,0001%) of particle size; thread connection: EN 148-1 Rd 40×1 / 7”or GOST 8762-75 OZ 40×4 mm - The filter sterilization is possible with 70°C heat - Thread connection can be adjusted to client’s specification – injection mould modification - Sterilization/disinfection: Autoclave, Ethanol - Weight 150 g (complete set); 50g without filter The half-mask is prepared to be used in the highest exposure clinical settings and a verified procedure exists to sterilise and disinfect it for repeated use. Therefore, it is a critical device for the protection of the lives of doctors and other front-line workers meeting people who are under suspicion of or have been proven to have COVID-19. The company is looking for a licensee with an interest for non-commercial usage (e.g. manufacture the masks for its own usage only or for healthcare institutions but then the masks must be provided free of charge to the final recipients). The partner interested in a licensing agreement will be provided with all documentation how to manufacture the half-mask including all technical drawings and information necessary to start own production.
