First, laser sintering technology
This technology mainly includes selective laser sintering, direct laser sintering of metal powder, selective laser melting, laser near-net forming and so on. This is also the mainstream technology of metal 3D printing forming technology, the most advanced and potential technology in the whole 3D printing system, and an important development direction of advanced manufacturing technology, which has been successfully applied to high value-added fields such as aerospace and high-end manufacturing.
Laser sintering technology, also known as metal powder sintering or metal powder laser forming technology, is designed with 3DCAD as digital information source and energy setting. It uses 3DCAD file as digital information source and energy setting to sinter fine metal powder layer into 3D parts.
However, due to the high technical content of metal 3D printer products, there are not many manufacturers who can develop this kind of equipment at present, so this kind of equipment is very expensive. The cheapest jewelry 3D printers on the market are millions of home desktop printers, and some high-end products even exceed tens of millions!
Second, 3D printing wax model
For many jewelers, printing with precious metals is not an economical choice. However, it is an important solution to upgrade jewelry to intelligent manufacturing if 3D printing equipment such as Daye 3D printer L 120 can be used to print wax patterns and improve the speed and accuracy of the most critical wax pattern manufacturing in the traditional jewelry manufacturing process.
As far as I know, it usually takes a skilled master at least three or four hours to carve a wax model of a ring. If he is not careful, he will have to start all over again. 10 wax model can be made in 2 hours, and the efficiency is improved by dozens of times!
