3D model description

Hermetic Mask is an element that allows to hermetically seal paper or fabric filters that provide a medium protection to the wearer and reduces the possibility of contagion, the main element is the frame that can be adjusted to many faces due to the flexibility of the PLA and the optimized printing parameters that are recommended in the printing guide, please follow them to obtain the desired results, the frame can be molded with warm water and close to the face, do it carefully to avoid burns, the dome accessory helps to move the filter element away from the mouth and nose avoiding possible contamination by contact and decreasing the condensation inside the filter, the neck adjuster decreases the tension on the ears due to the prolonged use of elastics and possible lacerations.

This project was born as a joint effort of all the organizations mentioned in the documents to give some guidelines regarding possible solutions to avoid the spread of Covid-19. It is a non-profit effort, and it seeks to raise awareness that the best solution is to stay at home.

The frame is a very fast printing element (about 19 minutes) and only 3 grams in weight which allows an optimal solution weight-cost-time ratio

Modifiable files are released with the encouragement of receiving feedback and photos.

Note: this element is not effective as an N95 HEPA filter, MERV 16, etc, but it releases under the premise that it is better to have some protection than none, understanding again that the best solution is to STAY HOME.

Special thanks to all the people who have collaborated to make this project a reality.

It includes information material launched by the Colombian Government and Universities on important issues related to Filters and possible official documentation needed for implementation in medical centers.
