Jewelry industry is an industry that requires high workmanship. The products are exquisite and smooth, and the details are accurate and beautiful. At present, the application of 3D printer in jewelry industry is mature, and it is also the early application of 3D printer. There are two kinds of materials widely used in the market-wax and resin. Each has its own strengths and makes up for the shortcomings. The wax material is easy to reverse in the later stage, and the process is mature and can be completely gasified, but the material is soft and the accuracy is not particularly high. Resin materials with acceptable hardness can be transported with high precision and smooth and delicate surface, but the reverse molding process requires high gasification temperature, and some resins cannot achieve zero ash.

At present, these two 3D materials are widely used in jewelry industry. Of course, it is said that a metal printer that can directly print gold powder has been developed, which should be a more direct weapon and worth looking forward to.
