Green Sand Castings are castings made using wet sand or "green sand" molds. The sand is not green in color nor do the molds use "greensand," a greenish color sandstone. Instead the sand is called "green" because it has moisture in it (like green wood) before the sand dries out when molten metal is poured in the mold.

 · A mechanical whir within a small warehouse adjacent to HCC is the casting call of a Viridis3D RAM123 robotic sand printer—a "game changer," as HCC President Tony Badamo calls it.

 · "Our green sand foundry uses a process very similar to what foundries in the '50s used to cast iron blocks and cylinder heads. Green sand, which is actually black in color, is similar to the sand at the very edge of the water at the beach," Roberts explains. "You can almost see the imprint of your hand and feet in it, but not quite. Green sand can be packed down very tightly, but it ...

That's why Dave Gingery offered alternatives to actual foundry supplies. Coarser sand can be used, and fire clay and water can be used to make green sand instead of using oil based binders. Baby powder or foot powder can be used instead of parting dust. There are a lot of alternatives available. The downside to alternatives is that sometimes the quality of your casting could suffer. But this ...
