Culcheth-based Rawwater Engineering Company Limited has designed a simple 3D-printed, click-together visor to help protect healthcare staff from Covid-19. Uniquely, the visor uses readily available, optically clear disposable film, rather than acetate sheet. It is lightweight (under 90g), does not mist up and is comfortable to wear. It can be worn over glasses and does not impede the vision or movement of the wearer.
The visor shields the whole face and can also protect the hair and neck from contamination. It has been in huge demand by community nurses, GP surgeries, care homes and hospices that do not have access to PPE and are at risk of COVID-19. Using its R&D 3D printer, Rawwater has been producing visors for free issue as fast as it can.
Rawwater is now looking to work with organisations that have 3D development capabilities, as well as plastic film producers and injection moulding specialists – all on a pro-bono basis, to further develop its visor design or take it into production.
Rawwater is giving its time freely and not taking an IP position. It has made available open source CAD STL files for 3D printing/ongoing development for injection moulding, and assembly instructions, on its website: https://www.rawwater.com/resources/index.php
“Having spoken to a number of frontline healthcare workers who were struggling to find PPE,” comments Rawwater Managing Director, Professor Bob Eden PhD, “we created a visor frame that could be sterilised with Milton or another suitable solution, and around which is wrapped a disposable film. We have had excellent feedback from all those who have tested the design.”
