Thanks!

UPDATE 31-3-2020:

THIS IS LAST RESORT DEVICE, NOT INTENDED TO BE A REGULAR PPE (PERSONAL PROTECTIVE EQUIPMENT) OR A N95 MASK. AS ANY 3D PRINTED DEVICE, YOU SHOULD POST-PROCESS, CLEAN, AND SEAL THE MASK IN ORDER TO USE PROPERLY. WE DON’T RECOMMEND TO PRINT FACE MASKS WITH REGULAR PLA, PET-G OR TPU MATERIALS, ANTIMICROBIAL/ACTIVE MATERIALS SHOULD BE THE CORRECT OPTION IN THIS CASE. THIS IS AN OPEN SOURCE FILE AND WE EXPECT YOUR COLLABORATION TO IMPROVE THIS DESIGN.

ABOUT NANOHACK 2.0

Our innovation is inspired by the scarcest products these days, face masks!

Basically, there is a breakdown in the global stock of face masks, and it is a basic necessity for general population in most countries. In many places the authorities have also recommended the use of these masks (or similar) on public transport. These masks, despite being effective, also have some problems like poor lateral fit, short lifecycle (about 8 hours), and have another even more serious problem. Respiratory viruses, specifically SARS-Cov-2 (COVID-19) can live up to 72 hours on different surfaces. This is a problem since using a conventional mask, at the end of the day we would have a high viral load trapped within millimeters of our nose and mouth, further exposing ourselves to these dangerous microbes. Our approach is to use active (antimicrobial) materials to address this problem, PLACTIVE®️ and MDflex®️.

HackThePandemic

Hospitals around the world are close to running out of face masks in the middle of the worst pandemic of XXI century! Our purpose as a company has always been related to make a positive impact and tackle #GlobalChallenges through #Innovation, #Nanotechnology and #AntimicrobialMaterials. Our purpose leads us to contribute to solve this problem in a low-cost, quick, and descentralized way through #DistributedManufacturing. We propose a #Reusable, #Customizable, #Monobloc, #Antimicrobial and #Antiviral #3Dprinted #FaceMask made with #Copper3D high quality nanocomposites #PLACTIVE and #MDflex.

Let’s HACK this #Pandemic with #Nanotech, #ActiveMaterials, #3DPrinting and #DistributedManufacturing.

INSTRUCTIONS:

CLEANING CONSIDERATIONS

Washing: Wash the equipment with soap and clean water.

Rinse: Rinse equipment thoroughly with clean water.

Disinfect: Disinfect the equipment to inactivate any remaining pathogens. Use chemical disinfection, not autoclave, since PLACTIVE® does not tolerate 80°C or more.

These are the most accessible chemical methods and germicides:

Method 1: Alcohol is effective against the influenza virus. Ethyl alcohol (70%) is a powerful broad-spectrum germicide and is generally considered superior to isopropyl alcohol. Since alcohol is flammable, limit its use as a surface disinfectant to small surfaces and use only in well-ventilated spaces.

Method 2: Most household bleach solutions contain 5% sodium hypochlorite (50,000 parts per million available chlorine).

Recommended dilution: 1: 100 dilution of 5% sodium hypochlorite is the usual recommendation. Use 1 part bleach to 99 parts cold tap water (1: 100 dilution) to disinfect surfaces. Adjust the ratio of bleach to water as necessary to achieve the proper concentration of sodium hypochlorite. For example, for bleach preparations containing 2.5% sodium hypochlorite, use twice as much bleach (i.e. 2 parts bleach to 98 parts water).
