3D resins are raw materials, not finished medical devices
Biomedical or food packaging certifications of photoreactive liquid photopolymers or 3D resins considering them as medical devices, or food grade packaging do not make much sense, nor provide any warranty, nor safety, nor biocompatibility assurance since photopolymer 3D resins are cytotoxic before and even after printing unless they are custom designed in tune with appropriate printing workflows to ensure their full cure, cleansing and safety.
Biomedical device and food packaging manufacturers need to design high quality products with the right raw materials "3D resins", workflows, processes and protocols to achieve the required biocompatibility for each class of biomedical device or food packaging system.
