Ducted Cooling Ducted cooling refers to the use of specialized airflow ducts to direct cooling precisely onto a printed model. This setup improves the cooling efficiency of the filament, particularly for overhangs, bridges, and fine details. By focusing airflow on specific areas, ducted cooling prevents warping, stringing, or smudging while maintaining overall print strength. Custom-designed duct attachments are often 3D-printed to optimize cooling for a specific printer model. Ducted cooling is especially beneficial for materials like PLA that require rapid cooling to achieve high detail and sharp edges. |
