Characterized as an open-source design, it makes people understand there are new ways of production with circular concepts. The only way to achieve this project, technically and conceptually is by digital fabrication, 3D printing to be more specific. Produced by 3D printed different polymers in tulle textile, it is generated a unique shape on the surface. The particular design, capable to call the attention, provokes interest, and defines an aesthetic that could be recognized generating an identity. The attachments to the ears are also 3D printed: they are made by a soft polymer that generates comfort connecting the frontal part to the face.
The core of the mask is a FFFP2 air filter protection from firm and fluid deleterious kinds of particles, placed between the face and the frontal surface. It is possible to set it there because of the filter support. The filter support is a 3D printed frame that allows changing the filter easily. The support is made with a soft polymer that is connected with the frontal surface and, in use, it is in contact with the face generating a closed area where the air becomes free of hazardous particles, by also reducing the air leakage. For the data collector sensor pack there is a a small dispositive that can be easily linked to the ear attachments. It is designed to be placed when in use and if it needs to be charged, it can be taken away and wirelessly charged. The electronic pack includes sensors to measure from the air Mq135, CO2, benzene, metals, NO - NO2, plus a Wifi and GPS module and a 9V lithium battery.
The unique shape of the frontal part is given by the base material (the tulle textile) and the 3d printed polymers. This process requires different steps of production: the initial step is printing the 2D drawing of the frontal part with a soft material over the base of the printer. The second step is the placement of the tulle textile: it has to be under tension in all its sides. The third step is characterized by a two materials printed face (one softer and one harder) under the first printed part and the tulle.
Once that the process is finished and out of the printer it is possible to see how the polymers take a 3d shape generated by the tension of the tulle and the hardness of the polymers. To reach the desired shape different drawings, patterns and sizes were developed, trying with a lot of filaments and 3D printers. The idea was to reach a shape capable to adapt to the human face and to the concept design.
