Filament Storage Guide
PLA /Tough PLA Storage: Because PLA is made of organic compounds it will absorb moisture if left out for long periods of time. For this reason, we recommend if it is not being printed with for 3-5 days that you store it an air tight bag or box with a desiccant such as silica gel. If it does absorb moisture the material will become brittle, and that can lead to clogging or breaks in the material in the Bowden Tube.
PVA Storage: When you are not printing with PVA for 1 day or more, you must store it in a air sealed bag or container, with desiccant. When you don’t, it absorbs moisture, ruins the material, and will most likely have to be disposed of. This is due to its water soluble nature and also being an organic compound.
When PVA does absorb moisture it can clog the core which could lead to the filament breaking off in the feeder, and other unforeseen issues.
Nylon Storage: When you are not printing with Nylon for 1 day or more, you must store it in a air sealed bag or container, with desiccant. Nylon can fully absorb moisture in just 18 hours when in the open air. This can lead to inconsistency in the print quality and ruin the strength and finish of the print.
ABS Storage: ABS is a more resilient material when it comes to absorbing moisture than PLA, PVA or Nylon; but it is not actually impervious to the effects of moisture like some think. If not printing with the material for more than 2 weeks we recommenced you store it an air tight bag or box with a desiccant such as silica gel.
