CIIRC RP95-3D

Personal Protective Equipment - CIIRC RP95-3D (Half-Mask) with an P3 Exchangeable External Filter Made With 3D Printing Technology (MultiJet Fusion)

Half-mask


The CIIRC RP95-3D protective half-mask was developed by a research team at the Czech Institute of Informatics, Robotics and Cybernetics CTU (CIIRC CTU) in Prague in one week. It is a personal protective device - a half-mask - with an exchangeable P3 filter that meets the highest degree of protection. The set consists of the body of the mask printed on special 3D printers 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 CIIRC R95-3D 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 coming in contact with people who are under suspicion of or have been proven to have COVID-19.

The half-mask can be 3D printed with the MJF technology. It is prepared to be produced on HP MultiJet Fusion machines of the 4200 and 5200 types, possibly the 5xx types but this model must be proved to provide the same quality product as the higher series. The selected technology guarantees optimal features such as flexibility, low weight and impermeability but also bio-compatibility. The half-mask is not meant for, prepared nor certified to be printed on 3D printers using other technologies (FDM, SLS, SLA, DLP), therefore it is not meant for home 3D printers either.

Owners of other but HP MJF technology can find a comprehensive summary and FAQs at www.ciirc.cvut.cz/covid.

Based on a "Memorandum about mutual and active cooperation in the matter of fight against the COVID-19 illness with the support of research and science" signed by the Ministry of Health of the Czech Republic, CTU and CTU’s start-up company Trix Connections, s.r.o., this start-up as the exclusive license holder undertakes to provide cooperation with production companies and participate in the research and development of this protective device as part of the fight against the COVID-19 illness.

To fight COVID-19 we provide the RP95-3D license for free.
