  1. 3d printed sand molds are great for limited production parts. After all it saves having to make the patterns. But if you are going to be producing thousands of castings a day traditional methods still work best. And with advances in 3d printing of metal alloys you can skip the casting process entirely. And go straight to finish machining.
