With regards to keeping the safety parameters of the half-mask as they were certified, we are sharing the printing data only with holders of HP MultiJet Fusion printers of the 4200 and 5200 types and we hope to be able to prepare the data for 500 types as well. After accepting the license agreement and inputting the HP serial number, HP MJF owners can download all the technical data and use it for a non-commercial purpose (i.e. at the price of cost, without a profit margin) in the agreement with the awarded license.
It is good to know that we are not capable to organize the production abroad. It will be up to the MJF holders and/or its partners to secure the suppliers of components needed for complete kit in required quality (i.e. silicone seal, diaphragm to the exhalation valve, external filter and rubber bands to attach the mask to the head). Only the mask body is 3D printed.
Please mind that the certificate is valid only in the Czech Republic as a result of expedited proceedings of the certification enabled thanks to the European Commission's recommendation No. 2020/403. Therefore, for use abroad it is necessary to obtain a certificate and an external filter.
In the following, the information needed to build the safety half-mask is provided. For the half-mask to be completed you need the following components:
The license is provided for free in order to cope with the current Covid-19 pandemic. We expect that the license will be prolonged until the current emergency state ends.
Newer versions of the builds are planned and they will be available at this website. Announcements of new versions will be provided on the public part of the website.
For you to begin, we recommend taking the following steps:
Technical support in the Czech Republic is provided by 3Dees Industries s.r.o. who is the official HP 3D Printing distributor in the Czech Republic. 3Dees Industries is coordinating all of the production logistics and masks completion with the 3D HP printer owners involved in the Czech Republic. 3Dess Industries also prepared the printing files for the approved types of HP MJF.
The silicone seal is in the Czech Republic supplied by 3D Tech.
