- High dimensional accuracy
- No draft required on the mold
- Products have excellent as-cast surface finish with no parting lines
- Reduced additional machining
Cons
- Costs can be high for low volume production
- Foam patterns are easily damaged or distorted due to their low strength
- Higher manufacturing cost due to die making, specialised equipment, refractory material, and labour
