Problem with filament - multiple fractures

[jtschichold 0]

I have found multiple fractures in the inner loops of a spool of PLA (UM gold) - see image.

Is it something that could be generated by an incorrect of storage of the spool ?

Thanks !

I have heard people say that this can happen if the air is too dry. After many months.

This is why I prefer my PLA *not* on spools. Or on larger spools.

Funny, I'll start storing filaments in my cellar with hams and wines.

Thanks gr5 !

I find this happens with older filament - they become brittle and it happens to some filaments that I 'dried' out by keeping them under a vacuum.

I have been developing models of things that I just produce in large numbers to use up my older filaments - things like plant pot trays, disposable mixing cups (for resins) - the filament just about works in the bowden etc, but if I then leave it in overnight I come back to about 10 pieces - so i always pull it out and re-load when i need it.

So I try and keep my filament 'fresh' and only order what I need (difficult )

Oh - and get a 3doodler - uses all my little bits of broken filament!

That will probably be even worse. Basically you want it dry but not too dry and more importantly you need to use it up within a year.
