Moisture’s Effect on the Filaments

Moisture can quickly devastate 3D printing filaments. The most prevalent filaments used for 3D printing, such as PLA, ABS, and PETG, are all highly prone to absorbing water from the atmosphere. As a result, a lot of issues can arise, including a reduced print quality. In fact, it has been established that filament tends to expand when subjected to wet conditions, resulting in a significant increase in thickness and width by approximately 6 and 10 percent, respectively. This causes the produced items to have less weight than the expected ones, thus lowering the density. Reduced print adhesion and tensile strength are also consequences of the expansion process.

Moisture Content’s Effect on Mechanical Properties

The ability of ABS to absorb moisture is relatively low. However, even a little amount of moisture might result in undesirable printing outcomes, such as lower print quality and filament expansion. Similarly, nylon has a high affinity for water molecules, which affects its mechanical characteristics, resulting in faulty printing outputs.

Dust Issues with Storage

Dust can be dangerous not only for humans but also for 3D printing filaments. Specifically, when spools of filament are kept in storage, dust accumulates on their surface. When loading the filament into the printer, the dust gets caught inside the hot end’s nozzle. This causes several problems, such as the filament becoming clogged. Additionally, dust on filament might result in poor printing quality, such as the generated prints having a rough surface and inconsistent layer adhesion.
