Reef Safe 3D Printer Filament (Ultimaker Material list attached)

[psumms]

Hi all, my son has a 3D printer and a couple of ideas for aquarium related products - One of which is in-water. Does anyone have any reef-safe 3D printing knowledge? I've attached a filament list of the Ultimaker compatible materials, from reading through, the CPE/PET, being FDA food safe would be the obvious choice but, does that absolutely confirm nothing will leach?

You need to go with PETG for the filament, this is reef safe and easy to find

Happy Printing!

OK thanks @ScottW - glad I checked, CPE/PET apparently is a completely different chemical composition to PETG!
