Cooling Fan A cooling fan is a critical component in many 3D printers, responsible for improving print quality by controlling the cooling process of the extruded material. It directs airflow onto the printed layers immediately after extrusion, helping the material solidify and preventing deformation or sagging, especially in overhangs and small details. Cooling fans are commonly used in FDM printers and can have adjustable speed settings depending on the material being printed. For example, PLA benefits from active cooling, while ABS typically requires less airflow to avoid warping. Proper fan settings are essential for achieving sharp details, smooth surfaces, and overall high-quality prints. |
