New Masks developed by a Tecnosinos' startup

A startup in partnership with Unisinos and Tecnosinos has developed a new shield face mask which is faster to make and less costly. Unisinos - University of Vale do Rio dos Sinos, located in the city of São Leopoldo / RS, Brazil, is developing a series of initiatives in order to face the new coronavirus pandemic through its Innovation Ecosystem (Technology Park, Incubator, Technological Institutes, School of Health and Polytechnic School).

Committed to developing a low-cost solution for the production of shield face masks s, used by doctors and nurses working on the front lines in the fight against the pandemic, the startup X4 Tecnologia has partnered with Unisinos and the Technology Park to develop a product that uses CNC laser cutting technology with acrylic PVC and PETG sheets. The manufacturing equipment used in the project is from Tecnosinos' laboratories.

To develop this solution, X4 Tecnologia analyzed several 3D printing projects, and discovered that the average production time was around two hours per piece. In order to gain agility and reduce the cost, the team redesigned the protector mask, manufacturing all parts using a laser cutting technology. Through this, it is possible to produce about 30 units per hour.

In addition to saving time, the average cost of each mask has been reduced from R$ 20.00 (U$ 3.80) to R$ 3.00 (U$ 0.57). The project has the capacity to produce up to 400 units a day, thanks to volunteers' participation and material donation. Raw materials have been donated by companies, startups, Unisinos Jesuits, the local community and Tecnosinos' employees. To increase production even further, X4 Tecnologia decided to share its solution with other companies and institutions that have the laser cutting machine. Those interested in reproducing the mask, can access the project at

As of April 10th, 1,300 units have been delivered, in the form of assembled kits together with a manual of instructions, to the Mobile Emergency Service (SAMU), Basic Health Units (UBSs), Fire Department and hospitals in countless cities around the state of Rio Grande do Sul.
