Consumable patterns, used in processes like lost-foam casting, involve the pattern being consumed or evaporated during the metal pouring process. This eliminates the need for labor-intensive removal of the pattern, does not require a core since the pattern itself can form complex internal geometries, and allows for the creation of molds without splitting them to remove the pattern, as it evaporates or burns away.
