Landlord, now there are 3d printers that can print jewelry directly, but it is very expensive, at least several million sets. If the company is not big, it is suggested to build a 3D DLP photo-curing 3D printer DP002, which can perfectly print personalized jewelry wax film with any shape, and then cast it into finished jewelry by lost wax method. The accuracy can reach micron level, and the efficiency is ten times higher than that of manual carving wax. The most important thing is that this machine can be bought for tens of thousands of dollars, and individuals can afford it.
