3D modeling and 3D printing have really important in the jewelry industry. At this point, we have compiled various information about 3D modeling and 3D printer used in the sector for you. Now let’s examine the things that need to be known and what you wonder.
There are many misconceptions regarding the use of 3D printing for jewelry. One thing is certain about 3D printing is that this technology is changing the rules of the game for anyone involved in the jewelery industry. We can comfortably express that jewelers from all over the world are in love with this technology.
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 most jewelers prefer to use other options. So let’s find out how layered manufacturing can help jewelry with 3D printing. First, let’s take a closer look at the traditional methods of producing precious items used by jewelers from all over the world. We will skip the technical details explaining the primary processes. Let’s examine these steps together.
How to Prepare Jewelry with 3D Modeling?
It is possible to print various jewelry and jewelery with 3D modeling and 3D printing machines. In this direction, we can detail the processes in question as follows.
Firstly the model is drawn in the design program. The model drawn is transferred to the memory of the 3D printer. Printing with UV light is made on the resin. When the process is completed, the model is obtained. Next step is washing and drying to remove excess resin. Then it is hardened in the curing machine. With this step, the 3D jewelry model is ready for casting. A plaster mold is created in accordance with the resin model. Liquid metal is poured after the plaster in the mold hardens. It replaces the resin. The final product is carefully removed, mechanically treated and polished.
Is Gold Printing Possible with 3D Printing?
As mentioned earlier, 3D printing serves to optimize the casting process and should not be seen as a complete replacement. The process of making jewelry using 3D printing should not be confused with direct 3D printing on metal, for example DMLS (Direct Metal Laser Sintering). In the latter, 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. However, 3D printing is still applied on precious metals. For example, designer Lionel Theodore Dean has 3D printed a series of gold ornaments for metal.
To summarize, 3D printing makes jewelry much more affordable. This technology can be supplemented with traditional manufacturing methods that are currently used by jewelers such as CNC machining. Many customers like to purchase unique pieces made on demand rather than regular items from stores. Some jewelery 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 “Order” button. So the jeweler does not have to spend extra money on showrooms or expensive storage facilities.
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 DLP printers.
