There’s more than one way to make a mold, especially for casting in metal. We’ve seen everything from 3D-printed molds to kinetic sand.

Witness the fascinating process of iron casting using sand molds, where molten metal takes shape with precision. Skilled ...

One way of doing this is to use rapid prototyping technologies. Rapid prototyping uses three-dimensional (3D) computer aided design to quickly fabricate a part or, alternatively, a sand mold for ...
