3D Printing for METAL SAND CASTING - Practical DEMO

Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 60% of all metal castings are produced via sand casting process.

Molds made of sand are relatively cheap, and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened, typically with water, but sometimes with other substances, to develop the strength and plasticity of the clay and to make the aggregate suitable for molding. The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models called patterns, by carving directly into the sand, or by 3D printing.

Here in this video we have used Pratham Series of 3D Printers for Pattern Making with Thermoplastic Material Like PLA & ABS.
Then have done the sand casting using that 3D Printer Pattern Only.
You can see the result of final product after Machining.
This approach saves Time & Money for Foundry owner, Product Developers.
and Yes, any of complex pattern can be easily created with 3D printing so no need to be labor oriented.
