With regard to scanning, I would like to tell you that the scanning we mentioned is not a conventional picture or text scanning. We mean three-dimensional scanning, which requires physical scanning. Many people have misunderstood this point. Our company has an imported scanner, which is specially designed to provide scanning services for customers. Some customers bought our engraving machine, but some stereograms could not be solved. So when they came to us, we promised to make two sets free of charge for them, but the price for the follow-up work was half of the market price. In addition, we do not accept external scanning. We only provide scanning services to our customers. Now many people find that they can use software to make stereograms. These people use special software, such as ZB, 3D, MAYA, etc. To tell the truth, the effect is OK, at least the sculpting effect is OK, the surface is smooth and free of traces, but it takes time. It takes 10 days or even half a month to complete a set of drawings, so the price of drawing is expensive, and a set of drawings is thousands. The scanned image is extremely fast, like the nuclear carving image, which takes an average of 2 hours, each has its own advantages!
