THE PROBLEM

Single Wall PolyPropyelene WORKS

PREVIOUS TESTS

image7

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!

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

RESEARCH AND RESULTS

Sani-Mask Assembly Guide

Sani-Mask GCODE files

We opted to share the GCODE files instead of STL as a way to ensure some form of quality control between printers. Files included for sizes small, medium, and large. ---File is validated ONLY for use on prusa i3 mk2/s or mk3/s (smooth sheet).--- More printers are on the way. ---Build surface MUST be treated with "Smart-Stick" from Smart Materials, and printed with Polypropylene from Smart Materials. We give no guarantee to the success of these files---

We are in the process of creating GCODE files validated for use with more printers. Please stay tuned for those files
