What is Sand Casting? What's the added benefit of 3D

Oct 17, 2019 The nature of sand, however, means that the molds used in the process are expendable and non-reusable. It is impossible to keep a sand mold intact when removing a casting. On the other hand, Sand Casting is ideal for high melting temperatures metals such as titanium, steels, and nickel. It is the only casting method that can handle these materials.
