ACH face shields were developed in response to in-depth feedback from doctors and medics on the front lines. They consist of an injection molded headband made out of PC resin, and an optically-clear, anti-fog PET visor. The two parts easily separate and snap back together. Both parts can be wiped down or sanitized in a bath.

* Easy to clean
* Hygienic (no foam/fabric)

Origins of the Face Shield and Open Source Design

At the onset of the COVID-19 there were many wonderful PPE designs created and shared with the 3D printing community, there were a few face shield designs that stood out for their elegance, practicality and proactive organization, including Prusa’s model, SeeMeCNC, and 3DVerkstan. They were all really amazing, and after careful consideration, we decided to go with the 3DVerkstan due to its limited number of parts, easy separation of elements for exchange or recycling, and great function.

The original Design of this face shield was created by Erik Cederberg / 3DVerkstan and generously distributed open source for the whole community under the Creative Commons license CC-BY-SA.

Peter Solomon of Ai Can Help has thus reworked and improved the model according to feedback from the medical community to improve performance and designed for mass production and injection molding.

Design Improvements

Among some of the improvements:

Extended distance from visor to forehead to accommodate goggles and larger respirators, closing off top more thoroughly to protect against falling liquids, added easier to attach and remove visor pins, adjusted visor for larger more complex coverage of the face, and increase the height for better structure while reducing the mass of plastic for better cost and ecological impact.
