3D printer is a new product. Although it has been around for a long time, it is very rare to use jewelry embedded in the application field. In other words, it has not been popularized. The 3D printer that first appeared was FDM. In layman's terms, it was a nozzle that could heat up the plastic filaments, extruded according to the nozzle, sliced ​​according to the 3D drawings on the computer, and painted layer by layer. Come out, after the plastic product is cooled, it is a 3D solid model, and then after modification, it becomes a more perfect solid model. However, this type of printer cannot be used in jewelry making. In the middle and late stage, light-curing printers appeared. After slicing the 3D solid model on the computer according to the projector, it was projected layer by layer to the bottom or top of the liquid resin tank. The accumulation of layers, and finally make a 3D solid model. This type of printing is faster and the molding effect is obvious. The disadvantage is that the overall physical model is not as large as that of FDM.

There are three types of light-curing 3D printers, one is DLP printer, the other is LCD printer, and the other is SLA printer. The difference between the three types is that the physical model printed by the DLP printer has small layers, and the LCD printer requires an LCD display, but the LCD display relies on the dot matrix to complete the display information, so the printing will have obvious layers. Do not use a 2K or 4K display to reduce layering, SLA printers belong to laser curing, which is faster and has the best actual effect, but the price is very high.

After introducing the printer, now introduce the application field of 3D printer in embedding.

In embedding, the molding must be made with high precision and the effect is obvious, so that the things that are poured out are accurate. Therefore, only a photo-curing 3D printer is used, and a 3D jewelry solid model is made on the computer according to the 3D drawing software. After slicing, it is sent to the printer, usually sliced ​​at 0.05-0.1 mm layer by layer. After a few hours of printing, a solid model of the jewelry can be printed. As shown below

If it is customized jewelry, the casting resin is printed immediately, and the casting is started immediately. If mass production is necessary, the high-strength resin solid model is printed, and then the purpose of mass production is completed according to the filling mold.
