3D printing is being nowadays so helpful, allowing companies from different sectors and individuals to contribute fighting the shortage of some sanitary materials like face shields and ventilators. Some examples are: Ford, who is prototyping transparent face shields for medical workers and first responders, with the goal of producing more than 100,000 per week; Carbon, a Silicon Valley 3D printing company, is making face shields and test swabs; or HP has designed 3D-printed parts, including hands-free door openers, mask adjusters and face shields, and is working on parts for a field ventilator.

In relation to this great news and contributions, there are some amazing advances in technology which are allowing 3D printing to be accessible to vision-impaired people. Engineers from Stanford University have developed tactile displays which allows blind people to design and modelling in an autonomous way, been able to perceive the different perspectives of the objects.
