Cooling Channels

Definition

Cooling channels are specialized pathways integrated into a part or assembly designed to facilitate the flow of cooling fluids, helping to maintain optimal temperatures during manufacturing processes. These channels are essential for preventing overheating, particularly in hybrid additive-subtractive manufacturing, where different materials are combined, and precise temperature control is crucial for achieving desired mechanical properties and ensuring the integrity of the final product.
