Prints below freezing

Hey, i have an idea for food storage bins in my freezer.

How do printed plastics hold up at freezing temps for extended periods? PLA? PETG? Other material choices?

I know some of the non-printed storage containers get brittle after prolonged use in the freezer....

Printed plastics are not airtight; doubt they'd serve well as storage dishes.

True, but that’s not what I meant.

I was thinking of making organizers/bins. Or rather corners &connectors for dividers made of cardboard or eventually lexan.

Re: Prints below freezing

There are probably a few filaments that won't get too brittle at freezer temperatures - perhaps looking towards flexibles and PETG just because they start a little more flexible is a good idea.

That said, my first inkling would be nylon. Not only are there food grade variants available, but it's widely used in variable temperature industrial applications already, so getting a formulation that has been well tested and characterized in a wide temperature range shouldn't be a problem.

I currently have PLA parts that have been sitting in my freezer for the last 2 years - I printed an adapter to allow bins to stack. They've done just fine.
