Chemical companies standpoints about certifiability of 3D resins
The biggest chemical companies in the World, such as BASF, Mitsubishi, Covestro (DSM-Somos), etc, who are already producting photopolymer 3D resins for Stereolithography, do not certify their liquid photopolymer resins as medical devices, despite having all the available resources, since it´s nonsense and lack of appropriateness and validity.
Manufacturers of medical devices or food packaging are and willl always be legally responsible and liable for the quality, safety and certification of their products.
Certifications which do not take into account the whole workflow for each specific biomedical application requirements, nor the customisation of the 3D resin (with careful selection of safe raw materials) to each 3D printer specifications, nor the control, monitoring nor prevention of the natural light power decay upon time of both the printer and the light box, nor the cleaning process in detail, cannot ensure that medical devices are safe for usage.
Certifications not covering all the mentioned aspects or just mentioning "rinsing parts with isopropanol" do not provide any warranty for the safety and readiness for use of any biomedical device or food packaging.
