metal. It makes complex parts with very little extra machining needed. The key part of this method is the foam pattern. This pattern shapes the mold space and turns into vapor when hot metal touches it. Picking the right foam helps control the quality of the cast part. It affects surface smoothness, size accuracy, and how well the whole process runs. Most people in the industry use expanded polystyrene (EPS) as the main foam for lost foam casting.
