Ideal for 3d printing reusable face masks, door openers, cell phone cases, door knob covers, etc.

There is a critical breakdown in the global stock of N95 masks, and they are a basic necessity, especially for Healthcare personnel who are at the forefront of fighting this disease. In many countries the authorities have also recommended the use of these masks (or similar) on public transport. These masks, despite being effective, also have some problems such as a 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/bacterial load trapped within millimeters of our nose and mouth, further exposing ourselves to these dangerous microbes.

Copper3D’s quest to alleviate this shortage has led to a low-cost, quick, and decentralized solution through distributed manufacturing.

They have created a reusable, customizable, modular, copper oxide infused PLA 3d printed respirator system made with PLACTIVE AN1™. A nano-composite, FDA-compliant, and ISO-certified PLA filament.

Enter NANOHACK 2.2: THE OPEN SOURCE RESPIRATOR MASK

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. THIS IS AN OPEN SOURCE FILE AND WE EXPECT YOUR COLLABORATION TO IMPROVE THIS DESIGN. - Copper3D

COPPER OXIDE INFUSED

Manufactured with PLACTIVE® an innovative Nanocomposite developed with a high quality PLA and a patented, scientifically validated and highly effective Nano-Copper additive.

MONOBLOCK STRUCTURE

NanoHack 2.2 is made of a monoblock PLACTIVE® structure to provide maximum protection against the external environment. Contrary to other concepts, NanoHack 2.2 is designed to be a strong and hermetic structure, sealed with a rim of Mdflex, a copper oxide infused TPU.

REUSABLE & RECYCLABLE

You can use this mask any times you want. The increasing use of single-used surgical masks and N95 respirators will have a detrimental effect in the ecosystem. To prevent this detrimental effect in our environment, NanoHack will be made with recyclable material.

MODULAR FILTRATION SYSTEM

NanoHack incorporate a novel modular filtration system manufactured with a copper nanocomposite polymer. This novel active filtration system also includes 3 layers of non-woven propylene embedded in nano-copper, and can house third party filtration materials.

TECHNICAL CONSIDERATIONS

NanoHack was conceived as an open source 3D printed face mask manufactured with active materials. These are some of the technical considerations prior to print NanoHack

In order to achieve optimum protection against the external environment, we recommend using a triple-layer non-woven polypropylene filter embedded in nano-copper developed by The Copper Company.

If you do not have access to this type of filter, the study by Anna Davies et al1 analyze the filtering efficiency of different materials. See attached table:

ABOUT THE FILTRATION SYSTEM OF NANOHACK

NanoHack was conceived as a 3D printed face mask manufactured with active copper oxide infused materials. We will use active filters of non-woven polypropylene (3 layers) embedded in nanocopper to get extra protection.

In the study by Borkow et al (2007)7, a 2.5 cm filter was designed containing a 2 cm thick top layer of 500 mg of non-woven polypropylen impregnated with 5% copper oxide particles. This study had a control that was non-woven polypropylen copper-free as a control.

Diffusion of viruses through filters containing copper oxide resulted in a significant reduction in viral titers from 0.47 log10 to 4.6 log10 depending on the virus analyzed.

CLAIMS ABOUT NANOHACK:

The purpose of the NanoMask is to offer the general population a degree of protection against airborne particles and to prevent the spread of liquid aerosols that could contaminate the airways.

• It is not an N95 mask. It is a face mask and should not be considered as a PPE.

• If you are a healthcare professional, you should use it as a last resort device: you cannot manipulate airway such as intubation, mechanical ventilation, fiberoptic bronchoscopy and similar procedures.

• You can use it in common spaces.

CLEANING CONSIDERATIONS
1. Washing: Wash the equipment with soap (e.g. liquid dish soap) and clean water.
2. Rinsing: Rinse the equipment completely with clean water.
3. Disinfect: Disinfect the equipment to inactivate any remaining pathogens. Use chemical disinfection if plastic part cannot tolerate 80°C. Different countries have different disinfection protocols. Here are the most accessible chemical germicides and methods:

4. Rinsing: If using chemical disinfection, rinse with sterile or clean water (i.e. water boiled for 5 minutes and cooled). Sterile water is preferred for rinsing off residual liquid chemical disinfectant from a respiratory device that has been chemically disinfected for reuse, because tap or distilled water may harbor microorganisms that can cause pneumonia. However, when rinsing with sterile water is not feasible, instead, rinse with tap water or filtered water (i.e. water passed through a 0.2 μ filter). Disinfection by immersion is recommended with a contact time of 30 minutes.
5. Dry equipment: Follow the previous step by an alcohol rinse and forced-air drying.
6. Store: Store equipment dry in closed packages.

Copper3D (www.copper3d.com) is a chilean company born in an academic process in the Master of Innovation at the Adolfo Ibañez University, the most important business school in LatAm. In this academic program, the founding team of this company met:

Andrés Acuña, Electronic Civil Engineer with 14 years of experience in the mining sector and specializations in automation of mineral processing.

Daniel Martínez, Physical Therapist & MBA, with 13 years of experience in management, marketing, innovation and new business models in the Healthcare industry.

Claudio Soto MD, Physician with vast experience in rehabilitation, regulatory aspects of Healthcare and process management in large health institutions.

We realized that more than 40% of amputees suffer some type of dermic disorders due to the use of their prostheses. This

phenomenon is also observed in non-amputee patients who use orthoses. The reason? The high bacterial burden present in these medical devices, which in contact with the skin can cause dermatitis, folliculitis, fungal or bacterial infections, among others.

But then we realized that the problem of bacterial burden is much more complex and huge: According to some studies, about 50% of all HAI’s (Hospital Acquired Infections) worldwide are due to the bacterial burden of medical devices that are difficult to maintain clean and sterilyzed.

After a long process of research, development and innovation, we realized that the ideal solution to this problem involved the molecular intervention of the

material with which these medical devices are manufactured. After discarding many options, we began prototyping a new polymer for 3D printing with an internationally patented additive containing copper nanoparticles, extremely effective in eliminating fungi, viruses and bacteria but safe for humans at the right concentrations.

With successful preliminary trials in Chile, we decided to start with the industrial manufacture of this material in Europe for later commercialization.

At the moment we have our first product available, it is a high quality PLA polymer with additive concentrations of 1 and 2%, it is called PLACTIVE since it is a PLA polymer with “active" properties in the elimination of a wide range of microorganisms.

We also developed a medical grade material called NANOCLEAN, it is a high quality PETG polymer with additive concentrations of 2 and 3% and aimed at more specific purposes in the world of medical devices.

We strongly believe in the impact that hard work, a great team and new technologies have on the quality of life of people, and in the power of innovation to reshape the future.

CLINICAL USE Nº10:

The Otoscope is one of the most used Medical Devices for its simplicity and versatility when it comes to examining ears, nose and throat.
But it has a weak point. The cone of the otoscope is the piece that comes into direct contact with the ear. It is a plastic piece (hence porous) that accumulates a high bacterial load if it is not cleaned or disposed of properly. This often causes patients (usually children) examined with contaminated otoscopes to leave the clinic / hospital with an otitis that falls within the group of Infections Associated with Health Care (IAAS).

You can find detailed instructions for its construction here, even with its lighting system:

CLINICAL USE Nº11:

3D PRINTED SURGICAL SEPARATOR Surgical separators are key pieces in any operating room in the world. Historically, they have been manufactured in stainless steel, but since it is a “passive” material, it allows to colonize quickly in the presence of even a minimal amount of microorganisms. A study published in the Journal of Surgical Research by the department of surgery of the U. of Arizona: (https://lnkd.in/dd_VNwA) concluded that these pieces can be perfectly manufactured with 3D printing, they take about 90 minutes to built, the final piece easily supports the forces necessary to fulfill its function within an operating room (+ 13Kg of Tangential Force) and only at ONE TENTH of the cost of the original piece of steel. If in addition to all these attributes, we add copper oxide infused and REUSABLE if manufactured with PLACTIVE OR NANOCLEAN (www.copper3d.com), so we have a new class of surgical, functional, cost-effective, in-situ manufacturing, and customizable, reusable separators that are manufactured with an ACTIVE material.
