Material
Brass
Brass is an alloy of copper and zinc. This versatile material offers a similar level of detail to gold and silver prints, and is available in a wide variety of colors and plating. Brass can be used for detailed miniatures, sculptures, or jewelry. It is also a popular choice for pre-print tests before ordering a piece of jewelry in gold or silver.
