One of the alternatives to the 3D printed face shield is a simple DIY foam based face shield. As 3D printers will not be available at all the places, this can serve the need too. This can be created with raw materials easily available at nearest stationery store. It needs a transparent OHP sheet, double side tape and an elastic band.

The OHP sheet will serve as the shield, there would be foam attached to the double side tape on the forehead. An elastic band will be tied from one end of the tape to the other end. The elastic band will help to hold the face shield over the face. The shield is easy to make and takes approximately 15 minutes to be assembled once we get all the required raw materials.

So if there is any need in your area and you find difficulty in getting a face shield or a mask, this can help you. You can start helping out the front line warriors. In case if there is any need in Mumbai, you can get in touch with Eduprime Technologies Pvt Ltd.

3D printed face shield

by Atit DubeyApril 8, 2020April 15, 2020CoVid-19Leave a Comment

Since the outbreak of the pandemic, it has become important that we keep ourselves safe. The prominent thing is to have limited physical contact with people as well as things. Since this virus can enter the system through eyes, nose or mouth, we need to protect it. The mask covers yours nose and mouth, and the disposable masks are to be disposed off in 6-8 hours of use.

To increase its lifetime, people have come up with face shields, which cover up the whole face covering the eyes and neck as well. The face shield is an open source idea which has been implemented by a lot of companies/individuals in 3D printing. They have fired up their printers to support the healthcare people, armed forces and others who are outside fighting the pandemic. The effort is now community driven and it is happening all across the world.

The 3D printed face shield has an easy design, approximately takes 20 minutes to print. It is easy to wear around the head. It grips around the back of your head. You can acquire the design from any of the open source developer and print it at your place. In case you need such shields, you can contact to one of the manufacturers.

Contactless Hand Sanitizer

by Atit DubeyApril 6, 2020April 15, 2020CoVid-19Leave a Comment

To ensure our safety, cleaning the hands is the most necessary & basic step. It has to be done at regular intervals for 20 seconds at least. WHO has also released a video showing the proper way to clean the hand in and around fingers and nails.

For this we need a sanitizer or a hand wash. Although, if our hands are not clean and we touch the containers to release soap/sanitizier, it can get infected. To avoid this, a lot of developers have created a contactless hand sanitizer / Soap Dispenser. It is one of the best open source projects available at the moment which you can develop at home as well, if you have the components and understand coding for it.

Contactless hand sanitizer consists of a sensor (IR sensor or Ultrasonic sensor) along with a servo motor (or geared DC motor in some cases) and a programming board such as arudino, Uniko Ekam etc. As soon as the sensor senses a hand in front of it, the Servo motor moves and pulls the sanitizer valve down. This releases the sanitizer or the hand wash. The user can put his hands away from the sensor so the servo moves back to home position; and the valve moves up.

The placement of the sensor can be varied as per the user. The mechanics to move the valve also can be changed. Changes are to be made as per the sanitizer container / bottle you have at your own place. Hook up the sensor, motor and a microcontroller to design one such product for your place. Such contactless hand sanitizers are also available at sale by few companies. Follow the links to get updated about the stories and ways to create your own contactless hand sanitizer.

Hand Sanitizer Holder

by Atit DubeyApril 5, 2020April 16, 2020CoVid-19Leave a Comment

The sanitizers have become too essential in the fight against COVID. It is like a sword to slash away the germs from our hands. The germs can be the infectious corona virus as well, and we have to anyhow prevent ourselves from them.

The sanitizers are not only a personal utility item but it is also required in public places such as society, office, mall, supermarkets etc . It is also important that sanitizer is held at a proper place and position. There have been various developments in this regard and the community has designed sanitizer holders. Since sanitizer is like a sword, it would need a scabbard to hold it.

The 3D printed holders are available for pocket friendly sanitizers and the big ones. The sanitizers can be held either in your hands or backpacks ; they can also be placed well inside elevators and other premises in your buildings and societies.

Go through the following links to check upon the various designs available. You can use one of them or modify as per your need and get it printed for you too.

3D Printed Ventilator & Splitter

by Atit DubeyApril 4, 2020April 15, 2020CoVid-19Leave a Comment

For the patients severely affected by the corona virus, they find difficulty in breathing. In hospitals, ventilators are used to supply oxygen to the patient’s lungs and remove carbon dioxide from it. This helps the patient to breathe.

The problem faced by many hospitals around the world is that there are limited numbers of ventilators compared to the number of patients. Due to the break in supply chain, it is not possible to manufacture those ventilators and make it available to the hospitals.

In time of this crisis, the 3D printing community has come up with a 3D printable ventilator. The prototypes have been tested and implemented in many countries. Not just the ventilator, the designers are also designing splitters for the ventilators. The splitters will help to support 1+ patients with a single ventilator. There are developments going in the design of 2-way, 3-way & 4-way splitters.

The open source project on ventilator is available in the below links. If you are looking to start anything on that, this link could work as a reference. All the updates are posted here.

If there is anything you can contribute, do your bit.

3D Printed Valve

by Atit DubeyApril 3, 2020April 15, 2020CoVid-19Leave a Comment

3D printers are extremely useful in the battle against corona virus [CoVid]. 3D designers around the globe are trying their best to help the people as well as the government to tackle this situation. They are lending away their time to design PPE (personal protective equipment) and also few other solutions to help out in this situation.

One of the ideas that helped a lot of patients and doctors in Italy, the most affected country in European Union, was to have 3D printed valves for reanimation devices. The hospital had shortage of valves due to the broken supply chain. Massimo Temporelli, designed this valve once he was contacted.

The 3D printed valve was tested as well implemented to save many lives in North Italy. The valve can be used to support the flow of oxygen from the oxygen tanks to the patients. Check out the story here.

Hands Free Door Opener

by Atit DubeyApril 1, 2020April 15, 2020CoVid-19Leave a Comment

It is known Corona Virus is contagious, and physical contact can lead to the entry of corona virus into your body. Social distancing is one of the ways to keep away from physical contact with other people and one of the best ways to stay safe.

Yet, a cause of concern is that the virus can stay on certain things for a while if it was in contact with an infected person, within & outside the house. The door knob will be one of the most touched objects, especially in public places. This can increase the germ manifestation on the knob. And it increases the chance of passing the virus to other people on their hands.

An open source project in the wake of corona virus is to create a hands free door knob. The door knob will have a separate handle attached to it, which can be held by the wrist instead of the bare hand. The handle is 3D designed and can be printed locally in any 3d printer (hobby or commercial ones).

The assembly is simple and the installation is also easy. Once installed, we can fit our wrist inside the handle and push down the door knob to open the door. Since most door handles are not wide enough to be opened via elbow, this project helps in doing so.
