THE PROBLEM
Single Wall PolyPropyelene WORKS
PREVIOUS TESTS
3D Prints that utilize infill CANNOT be sterilized. As seen in this picture. The PolyPropylene print on the left was put through the autoclave, and still grew bacteria. The one on the right was assaulted with bacteria and then autoclaved, and grew a TON of bacteria!

PREVIOUS TESTS
Conventional tested the SURFACE of a 3d print by swabbing it and then trying to grow off of the swab. This test is irrelevant to 3d printed objects, since they are not manufactured in the same way. They must be submerged in growth media for a quantitative test

KCUMB's research showed that if an object was 3d printed in a single wall via "vase mode" utilizing polypropylene, it could be successfully sterilized by conventional methods, including autoclave, household bleach, or rubbing alcohol! The picture above shows material that was assaulted with bacteria and then sterilized via various methods. The clarity of the liquid shows there is no bacteria present!

The SANI-MASK prints up to 1000% faster than the leading 3d printable mask (30 minutes vs. 4 hrs). Leading to a vast increase in throughput, enabling more people access to the masks they need.

Due to the efficient use of materials, each mask only costs roughly $5 USD in material usage, and can be printed on consumer-grade 3d printers! it is compatible with ANY flat filter medium. Including 100% cotton, blue shop towels, sterilizing wrap, MERV filters, and HEPA filters.

The mask creates an effective seal for a wide array of face shapes, and requires no heat treatment to adjust the fit. This is thanks to the slightly flexible nature of polypropylene. In fact, the fit quality increases even more over time, thanks to the slight "memory" effect of polypropylene
