Which industries are suitable for the 3D printing process using photosensitive resin materials?

Owner, there are already 3D printers that can directly print jewelry, but they are very expensive, at least several million. If the company is not large, I recommend PioNext's light-curing 3D printer DJ-89, which can perfectly print any personalized jewelry wax film, and then use the lost wax method to cast into the finished jewelry after printing. In this way, not only the accuracy can reach the micron level, but also the efficiency is more than ten times higher than that of hand-carved wax. The most important thing is that this machine can be bought for only tens of thousands of dollars, which can be affordable by individuals.

How to make 3D printed model materials?

China is the world's largest producer of jewelry. With the rise of China's middle class and high-income class and the awakening and pursuit of beauty, the sales of jewelry in China have exploded year by year, reaching an annual sales volume of hundreds of billions.

With the industrialization of 3D printing in the jewelry industry and the application of 3D printing in the jewelry industry, we believe that it can be divided into two categories:

One is indirect manufacturing, usually 3D printing wax models for casting, rather than using direct metal 3D printer technology. It is printed by a high-precision jewelry 3D printer using waxy materials. Then, put the wax model into a container, and pour liquid plaster into the container to fill and cover the wax model. When the gypsum has solidified, take out the model and put it in a furnace to melt the wax material, and the remaining gypsum part becomes an inverted mold. Then pour the molten jewelry metal into the plaster mold, wait for the metal to solidify, and finally remove the plaster part. Compared with the traditional mold opening method, this method has greatly enriched the jewelry design, shortened the jewelry manufacturing process, and improved the efficiency of jewelry manufacturing. In addition to the 3D printing wax material, there is another way to 3D print the resin material, using resin instead of wax to complete the investment casting.

The other is to directly print precious metals or plastics. There are also two technologies for direct printing of metal powder. One is SLM selective laser melting technology, which is especially used to print gold. One is SLS selective laser sintering technology, which uses a laser to heat metal powder to form a solid before it reaches its melting point.

In addition to the above two aspects, the application of 3D printing technology in the jewelry industry will give birth to a digital manufacturing business platform and business model. A large number of 3D printers will print the modeling data sent from the website platform into a wax model, and then transfer it to another one. The factory proceeds to the next process. Finally, it reaches the consumers by express delivery. Personalized customization and standardized mass production will no longer conflict, but become the norm in our lives.
