Jewelry 3D printers work by building three-dimensional entities by depositing material layer by layer based on a digital model, a technique known as "additive manufacturing." This is completely different from traditional "subtractive manufacturing" (such as carving and polishing) in jewelry making, enabling more complex and intricate designs.
Design Modeling: Designers use professional software (such as Rhino and 3DESIGN) to create a 3D digital model of the jewelry, precise down to every curve and detail.
Data Conversion: The 3D model is imported into slicing software, converted into printer-readable instructions (G-code), and the printing path for each layer is planned.
Layer-by-Layer Printing: In SLA/DLP technology, liquid photosensitive resin is used, cured layer by layer by ultraviolet laser or projector.
In 3D printing wax models, the printer deposits wax material or wax-containing resin layer by layer to form a high-precision wax model.
Post-processing and casting: After the printed wax model is cleaned and the support is removed, it is used for lost-wax casting. The wax model is embedded in plaster and heated to melt the wax, forming a cavity. Molten metal (such as gold or silver) is then poured in to obtain a metal jewelry blank. The finished product is then completed through grinding, polishing, setting and other processes.
