3DMASK - 3D printed mask
Project description
The 3DMask solution offers a better face contact than a standard tissue mask, and consequently a better protection if the correct filter is applied. The wearer of this mask has a less claustrophobic feeling thanks to the space between the mouth, nose and the filter.
This mask is an open-source solution which can be 3D printed by anyone around the world using standard 3D printing filaments. The 3D printed pieces are washable and can be used many times, being the limits 1)the properties of the filaments used (please consult the Safety Datasheet of the filaments that you use) and 2)the cleaning process used.
To allow the biggest flexibility possible to all makers around the world different filter supports have been developed and are made available as part of this open source solution.
The 3DMASK is developed under the CERN against COVID-19 program.
3DMASK - Exploded view
Prior to submission as open-hardware, the grilled support filter version of the 3D mask was sent to a certified lab to perform some tests, in accordance to the applicable standards. The objective was to determine the performance of the mask in terms of penetration (i.e., filtration), breathability, CO2 concentration, flammability and usability. The results are mentioned here (link?). It is important to mention that these results only represent the specific filter material (name ??) sent with the grilled support to the lab. The performance of the mask will depend of the filter applied.
The 3D mask does not constitute any certification for the placement on the market. Such legal procedure is of the entire responsibility for the licensee manufacturing the product, according to the applicable certification process in the market where the mask will but used. The certification procedure will require independent tests, therefore, the results mentioned above are not used for this purpose.
