What environmental factors can impact FDM printing quality?

The correct answer highlights that environmental factors such as humidity, temperature, and airflow significantly influence the quality of Fused Deposition Modelling (FDM) printing.

Humidity can affect how materials behave during the printing process. For instance, some filaments, particularly those made from nylon or PLA, are hygroscopic, meaning they can absorb moisture from the air. This moisture can lead to issues such as warping and degradation in layer adhesion, negatively impacting the final print quality.

Temperature plays a crucial role in the extrusion process and the adherence of layers. If the ambient temperature is too low, the filament may not melt properly or cool too quickly, leading to poor adhesion between layers, resulting in weak spots in the finished print. Conversely, an environment that is too hot can cause issues such as stringing or oozing, where excess filament is released during printing.

Airflow is another significant factor. Strong drafts or inconsistent air movement can cause uneven cooling of the printed material, leading to warping or distortion. Maintaining a consistent environmental condition helps ensure that the print adheres properly and maintains its intended shape throughout the printing process.
