Hi, Good day,
I am currently working with translucent blue PETG filament. In order to describe the nature of translucent blue pigment/dye present in the PETG filament in my research article, I am in need of the chemical name of the dye. I searched the internet and couldn't find the relevant information. There is no information on the product packaging either. It would be incredibly beneficial for me to continue my research if someone could tell me anything about this. Many thanks in advance.
