An integration of 3D printing and pharmaceuticals has resulted in a novel type of mask which attacks the virus when viral particles come in contact with it. Developed by Pune-based start-up firm Thincr Technologies India Private Limited, these masks are coated with anti-viral agents known otherwise as virucides. The virucidal mask project is among the earliest projects to have been selected for commercialization, by Technology Development Board (TDB), a statutory body of the Department of Science and Technology, Government of India, as part of the Government’s fight against Covid 19.

The project received financial support from TDB as part of its search for novel solutions to fight COVID-19, in May 2020. Following this, an agreement was signed on 8th July, 2020 for developing the masks. The 2016-incorporated firm claims that these cost-effective masks are more effective in checking the spread of Covid 19, in comparison with ordinary N-95, 3-ply and cloth masks.

The coating has been tested and shown to inactivate the SARS-COV-2 virus. The material used for coating on the mask is a Sodium Olefin Sulfonate based mixture. It is a soap forming agent with hydrophilic and hydrophobic properties. In contact with enveloped viruses, it disrupts the outer membrane of the virus. The ingredients used are stable at room temperature and are widely used in cosmetics.

The filters of these reusable masks have also been developed using 3D printing. With intensive study, it has been found that the masks have bacterial filtration efficiency higher than 95 percent. “In this project, for the first time, we used 3D-printers to make multilayer cloth filters to precisely fit for plastic-moulded or 3D-printed mask covers”.

Thincr Technologies India Pvt. Ltd. has applied for a patent for this product and commercial scale manufacturing has also started. Meanwhile, 6,000 virucidal masks have been distributed by an NGO to four Government Hospitals in Nandurbar, Nashik and Bengaluru, for use by healthcare workers and also to a girls’ school and college in Bengaluru.
