3D Modeling and 3D Printing in Jewelry Industry

Manufacturers in the jewelry industry can produce more products in a shorter time, thanks to 3D printing technology. It is possible to state that jewelers all over the world have increased their profit margins thanks to 3D modeling.

3D printing in the jewelry industry has nothing to do with direct metal 3D printing technologies as most people think. While it is possible to use direct metal printing, the costs are very high and that is why jewelers often prefer to use other options. 

What is 3D Modeling?

3D Modeling is a type of modeling that refers to the design of objects in 3 dimensions. The term 3D modeling refers to the process of creating a three-dimensional representation of an object using specialized software. This representation, called a 3D model, can convey the size, shape, and texture of an object. 3D modeling, which can be used extensively in almost every sector and provides various advantages to the sector where it is used, is also widely applied in the jewelry industry.

How to Prepare Jewelry with 3D Modeling?

First of all, the model is drawn in the 3D design software. The drawn model is transferred to the memory of the 3D printer. The model is drawn on the resin with UV light. When the process is completed, a resin model is obtained. Wash and dry to remove excess resin. It is then hardened in the curing machine; with this step, the 3D resin jewelry model is ready for casting. A plaster mold is created in accordance with the resin model. After the plaster in the mold hardens, liquid metal is poured. It replaces the resin. The final product is carefully removed, mechanically treated, and polished.


Is Gold Printing Possible with 3D Printing?

The process of making jewelry with the help of 3D printing should not be confused with direct 3D printing on metal, such as DMLS (Direct metal laser melting). The object is created using metal powder, and using gold or other precious alloys is very expensive. Also, for direct metal 3D printing, the minimum element size should not be less than 1-2 mm. Whereas, jewelry usually contains many small elements.

To summarize; 3D modeling, 3D printing make jewelry manufacturing much more economical. Many customers like to buy unique pieces from stores that are made on-demand rather than regular items. Some jewelry entrepreneurs produce all of their products on demand. The product is not available before the customer selects the product on the site and clicks the “Place an order” button. Tailor-made jewelry is produced in a much shorter time and at less cost.

Next Generation 3D Printing for Jewelry Industry – Uniway Optronix – 3D Printer Manufacturer

Uniway Optronix is a manufacturer of highly precise 3D printers for direct casting applications in the jewelry industry. Uniway Optronix DLP 3D printers provide fast and high-quality 3D printing with high precision and provide high-quality printing results even on the most sensitive models. Having the first and only design in the world with its feature of top-down table orientation makes it stand out from its competitors. Thanks to this feature, parts printed up to 20% lighter. That means up to 20% less resin cost. Also does not need spare parts. The very thin support connection allows the supports to be removed easily. The same size stones can be placed on the prototype very easily in the same way. Printing can be made in thicknesses less than 20 microns. Uniway Optronix guarantees that the weight difference for the entire platform is within ± 1%. This deviation is more than 10% in most 3D DLP printers.
