A group of Cobourg/Northumberland organizations have got together to produce PPE Face shields – that’s Personal Protection Equipment that looks like a welder’s face shield except it’s transparent. You can figure them out from the photos below – the only photo of someone using one is the one below right – click to enlarge. It seems the initiative started with 3D printing at Venture 13 but many others are helping. There’s a GoFundMe initiative to raise money to help – if it’s oversubscribed, money will go to local Hospital Foundations (NHH and Campbellford) – see link below. There’s also a web site coordinating the effort. According to the organizers the design originated with the Czech company Prusa in consultation with the Czech Ministry of Health and they say that “All tests were performed by leading Czech laboratories and hospitals to ensure conclusive and reliable results.”
They probably do not comply with the N95 standard but they are obviously useful to front-line Covid-19 people since they say that “Hundreds of face shields have already been delivered to Northumberland Hills and Campbellford Memorial Hospitals, to long-term care facilities and retirement communities across the County, to emergency responders and essential services.”
But the Czech designers say that “the shield alone is not a replacement for a surgical mask or respirator. It should always be combined with a surgical mask or respirator”. Also, cleaning methods have not yet been fully tested so they are initially one time use.
Here is some info from John Hayden at CFDC:
The Prusa RC3 Face Shield was the model initially used by InkSmith in Kitchener-Waterloo (the biggest project of its kind in Canada – we are in contact with them through our partnership with Chris Daniel at Durham College). They have since launched Canadian Shield. InkSmith has Health Canada approval (this article has some good photos). The basic Prusa design is being used all around the world because, unlike other designs, it is open source, universal and available so that all production partners can be easily united onto one program.
The Northumberland.io group is currently seeking Health Canada approval (Class 1 medical device). Chris Gillis P. Eng (Durham College) is leading.
All efforts are voluntary and all units are donated.
Currently 77 units are being produced per day but it is hoped to do more. They have an immediate need for “Buttonhole Elastic Bands” – I’d guess elastic cannot be 3-D printed.
