Are you a health care professional in need of solutions developed by helpfulETH?

Our products are free for any healthcare institution in Switzerland.
We will do our best to meet every demand, but cannot guarantee immediate fulfillment of high volume requests.

Face Shields. We produce simple RC3.1 face shields for use by healthcare personnel or for protection when engaging in interpersonal contact. The shields are manufactured according to an optimized construction of the Prusa model. We use injection molding for the frames and punching tool technique for the visors, made out of PET.

The project “Face Shields for Switzerland” is a cooperation of Hochschule für Technik Rapperswil, ETH Zürich and industry partners Geberit and Swiss Prime Pack under the umbrella of helpfulETH. We have already supplied more than 1000 face shields to facilities throughout Switzerland.
