When the Covid-19 outbreak crippled the world, P Mohan Aditya, a 3rd-year Mechanical Engineering student from SRM University-AP, made an initiative of developing the highly useful face shield made from bio-degradable substances. He named it “Facial Shield 2.0”, as it was an improved version of the ordinary face shields. The innovative features added to it helped him to earn the copyright to his credit. On May 16, 2020, Aditya filed an application on the face shield design under the IPR (Intellectual Property Rights) with Indian Patent Office, located in Kolkata, India. In 2021, a copyright was granted for the” Face Shield for Humans” with a Design Application Number of 329364 – 001.
The face shield 2.0 serves as the outer defence to the mucous membranes (nose, eyes, and mouth) and comes with a transparent visor made of a thin layer of 175-micron reusable plastic and a highly durable headband made of 3-ply corrugated cardboard. The cardboard’s bursting strength is 16kg/sq.cm, which is quite durable yet lightweight. Due to the use of biodegradable materials, the price of a face shield is at an affordable cost of INR 15. The face shield 2.0, made with firm elastic, is adjustable and suitable for all head sizes for comfortable wear without hurting the head.
Shri Adimulapu Suresh, Hon’ble Minister of Education, Andhra Pradesh and Sri Nandigama Suresh, Hon’ble MP, appreciated the student’s efforts in the Secretariat’s premises. Aditya received high accolades from the guests present on his first successful invention. They also distributed face shields among state police officers, paramedics and other frontline workers deployed in the containment areas.
In a conversation with P Mohan Aditya, he says, “With an increasing environmental degradation, we should move to the eco-friendly alternatives to develop products/services. Therefore, I thought to develop face shields from reusable plastic and cardboard, which are easily degradable. After discovering a shortage in the supply of Personal Protective Equipment (PPE) globally, the idea struck my mind. Immediately I started researching on developing a piece of standard equipment to combat the Covid-19 pandemic. I am thankful to Mr Ravi, the attorney at SRM-AP, who supported me throughout the tough times by answering all doubts amidst challenging circumstances.”
Aditya’s invention turned out to be a successful project both for the University and the public. The leadership team of SRM University-AP – Dr P Sathyanarayanan, President, Prof V S Rao, Vice-Chancellor, and Prof D Narayana Rao, Pro-Vice-Chancellor expressed their happiness on Aditya’s success by congratulating him on developing the face shield and making use of eco-friendly technology.
Using the CAD software, Aditya designed the transparent visor of the face shield and fabricated the remaining headband with the CNC machine. The CAD model was used as the input to the CNC machine, Following the design, the CNC machine analysed and cut the cardboard and transparent sheet accordingly.
P Mohan Aditya’s another innovative design on “building block for bed” was applied for a copyright on 09-08-2020. The building block for bed is again an innovative work of making beds using reusable materials for COVID 19 patients. He and his team also successfully created an electric bicycle using a 24V 250Watt DC motor powered by a 12V and 12Ah battery as a team assignment. Aditya desires to be a successful engineer and creator of such inventions for the betterment of society.

Dr. Panchagunula Jayaprakash designs an improved alternative to regular masks
Dr. Panchagunula Jayaprakash, Assistant Professor, Department of Mechanical Engineering, has designed a FACE SHIELD embedded with 3D printing technology. During this pandemic that has led to an unprecedented global crisis, this face protection devised to protect users from the Novel Coronavirus, is made available at the minimum rate of Rs. 20 each. The major drawback of the commercially available Face Shields for engineering applications is its heavy weight which causes discomfort if worn for a longer period of time. This face mask that uses 3D printing technology alleviates the limitations of the regular masks currently used by doctors, policemen, and journalists.
Head mounted Face Sheild
“With the advent of Covid-19, and due to the shortage of personal protective equipment, the health workers such as Doctors, Sanitary staff and Police are also getting infected. As they are the backbone of the society, I thought of designing a light weight Face Shield using 3D Printing (3DP) or Additive Manufacturing technique. The rudimentary advantages of 3D printing technology is the design flexibility and less lead time to manufacturing. “, explains Dr. Jayaprakash.
Creation of CAD model
The regular masks barely cover the nose and mouth, whereas the Face Shield will be able to protect the eyes, mouth, nose, and ears so that one cannot get infected by the virus. Some of the medical and police personnel who use the regular masks suffer from facial irritation, making the Face Shield a comfortable and more effective alternative for all government officials on Covid-19 duty.
Dr. Jayapraksh further says, “While manufacturing the Face Shield, 3D printing technology is used for designing a headband, upon which a 100 micron thick transparent plastic sheet is attached to ensure superior protection against the virus. It prevents air, dust, and liquids that are contaminated to come in contact with people. Also, there are no probable side effects on using the mask. If the government approves of its marketing, the face mask can be distributed among the public to prevent the widespread of Novel Coronavirus.”
