The "3D" of 3D hard gold is the abbreviation of 3D, which means three-dimensional graphics. Real three-dimensional space, with real distance space. It is also gold, but the new generation of 3D hard gold uses different techniques in different positions, some are polished and some are frosted, resulting in a contrast between light and dark. The layering of colors is clearer, the three-dimensional sense is stronger, and the texture is different. In terms of hand feel, some places are smooth and delicate, and some places are slightly matte and rich in hand feel.

3D hard gold is not real gold, but a metal alloy made of other metals and plastics. The main components of 3D hard gold are copper, zinc, aluminum, tin and so on, and usually contain a certain proportion of real gold or real silver. This alloy is made of 3D printing technology, which has good strength and wear resistance, and can obtain metallic texture.

3D hard gold is a new material, which is often used in high-end products such as jewelry, watches and jewelry. Compared with pure gold, 3D hard gold is relatively cheap, so it is popular in the market. However, it should be noted that 3D hard gold does not have the same asset preservation and appreciation potential as pure gold, so consumers should treat it rationally when purchasing.
