YES!!! Please practice your own due diligence in this regard. Ensure that you have first cleaned the product, before use. Please follow the “RC3 Face Shield” Specifications to properly clean the Face Shield after every use.
Due to the way in which they are manufactured, 3D printed materials are frequently more porous than typical medical device materials, allowing them to harbor microbes if they are not carefully sterilized. Medical sterilization techniques require heat, radiation, and chemical sterilization processes. Any 3D printed device made for use with patients must be able to withstand repeated exposure to these processes. Most common 3D printing materials will warp, melt, or lose tensile strength when exposed to medical sterilization. There is some sterile 3D manufacturing but it is rare, mostly proprietary, and usually already located in a hospital or research lab. Not usually conducive to mass-scale production.
3D-printed PPE can be used to provide a physical barrier to the environment. However, 3D-printed PPE are unlikely to provide the same fluid barrier and air filtration protection as FDA-cleared surgical masks and N95 respirators.
Check the 3D-printed mask’s seal for leaks.
Confirm that they can breathe through any makeshift filter materials.
Exercise caution in surgical environments where the need for liquid barrier protection and flammability is a concern.
Recognize that the mask may not provide air filtration enough to prevent transmission of infectious agents.
Safely dispose of infectious materials and disinfect any part they intend to reuse
3D printed N95 face masks or respirators require qualification and compliance to the N95 standard.
PETG (Polyethylene Teraphthalate Glycol): Yes, 100% Percent recycable
PLA (Polyactic Acid aka Corn Starch): This material is regarded as biodegradable.
