Description

 

This is an attempt at a reusable N-95 mask. The hardest hurdle for any mask to be considered effective is maintaining a proper seal. Without a proper seal and fit around the face, the mask is not protecting the wearer.

I have solved this problem with a unique approach in making the seal malleable to the face with a durable and rubber like composition. The seal is made from Silicone, Corn Starch, and Mineral Spirits. I have developed 4 main prints to achieve this process. One print is the mask itself while the other three are molds in which the seal itself is cast.

The seal is then applied to the mask and creates an airtight seal around the wearer's face only allowing airflow through the filters in the mask. (The mask and seal are aimed at one size fits most approach. However, all prints are scalable even down to child size)

The techniques and tools needed to replicate this process have been centered around ease and accessibility. All materials needed to produce the mask and seal can be purchased from a local Wal-mart. (With the exceptions of the prints themselves)

I have provided a link to a tutorial video explaining in full detail how to seal the mask as well as create the seal and assemble the two. The whole process takes roughly seven days from after the prints are done. This is mainly due to curing time.
