We coordinate the production and assembly of much-needed respirators. Major components of this protective half-mask are being produced with the use of HP Jet Fusion 3D printers

The respiratos have been developed by the Czech Institute of Informatics, Robotics and Cybernetics, part of the Czech Technical University in Prague (CIIRC CTU) as a protective FFP3 class half-mask with exchangeable external filters named RP95-3D.

Our task is to coordinate production of the half-mask on all installed HP Jet Fusion 4200 and 5200 3D printers across the Czech Republic and and provide technical advisory related to the MJF technology. We also assembly the final product, which alongside the 3D printed body and other minor components consists of silicone gasket, Sigma P3 filter and clamping rubber bands.

The respirator was successfully certified as a half-mask with FFP3 safety level according to the CSN EN 140:1999, with the use of HP Multi Jet Fusion. This technology ensures non-porous quality of 3D printed parts. Further development of the product will take place at CTU with the goal to improve design, simplify final assembly and prepare it also for other production technologies.

You can find more information about the respirator development project on web of ČVÚT (CIIRC).

CURRENT SITUATION:

We handed over 3000 pieces of 3D-printed respirators. We keep our production capacity going to bridge high series production on injection molding technology which is about to be launched in upcoming weeks. Protective gear is simply scarce these days. Many thanks to all partners for their help and support! ŠKODA AUTO helps not only with the printing, but also with delivery of all components to the production site. Universities and other companies take their part in the production of the half-mask. Cash Only provided us free of charge with their beautiful premises in Liben for final assembly. We also thank Hewlett Packard for its technical and material support during the 3D manufacturing process.

Last but not least, we would like to sincerelly thank all the volunteers, Czech and international students of the First Faculty of Medicine at Charles University, Prague, members of the Czech scouting and all the other people that came to help with this non-for-profit project. Without them we would not be able to do the assembly of all components in time! We hope we can rely on their help even in the coming weeks.

We Thank Our Partners For Their Help
