Material handling and storage

When you have multiple spools of material in use, or do not print with a material, it is very important that you store them properly. If material is stored incorrectly, it may affect its quality and usability.

To keep your materials in optimal condition it is important that you keep them:

  • Cool and dry
  • Out of direct sunlight
  • In a resealable bag

The optimal storage temperature for PLA, Tough PLA, Nylon, CPE, CPE+, PC, TPU 95A, PP and Breakaway is between -20 to +30° C. For ABS the advised temperature is between 15 and 25° C and for PVA 0 to 30 °C. A relative humidity of below 50% is recommended for PVA, TPU 95A, PP, and Breakaway. If these materials are exposed to a higher humidity the quality of the material can be affected.

You can store the material in a resealable bag, including the supplied desiccant (silica gel). For PVA it is advised to store the spool in a resealable bag with the supplied desiccant directly after printing to minimize moisture absorption.
