### About

Sterling Silver (92.5% silver) is a high quality silver alloy commonly used in jewelry and other skin-safe applications. With several finishing options and the ability to showcase intricate details, 3D printing Silver offers a professional, finished look and feel. 3D printed Silver will tarnish over time, but can be polished to achieve a like-new surface. This material is a softer metal that will be more malleable with thin features. Natural and Polished Silver can be ordered through our online platform, for Antique, Satin, Sandblasted, and Fine-Detail Polished finishes please reach out to sales@shapeways.com.
