Hello! I have a bit of a problem that needs solving. I’m prototyping a drink bottle for a major work, and henceforth need to find a way to waterproof its various components (it’s not your average bottle). It would be really great if the waterproofing technique could help render the bottles components as food grade! Thankyou!

I think you will need to provide more info – what wall thickness, what materials is it made of, etc etc. The more you provide the better the advice will be.

What pinchies and Domsk said… PETG for the food grade part - the rest well, could you be a little more vague? :wink:

I think its probably safe to make some reasonable assumptions though.

Ok, since it will be rocket powered, you probably want to use a copper-fill filament to conduct away the heat…

Haha of course! I’m printing with a MakerBot Replicator Gen 5, using their standard PLA filament with a resolution of 0.1. Wall thickness at the moment is default, which I believe to be 1mm.

This will not be food safe, but if you print in ABS you can seal all the surfaces with ABS juice or plain acetone.
