Laser embossing is a sculpture based on the surface of the material, using the laser beam as a "tool" to cut or burn the material to form a concave and convex three-dimensional graphic process. In this article, we will give you some examples of the differences between 2D and 3D laser sculpting based on the need for lower machine costs, high efficiency, and high precision.
The core components of laser processing relief equipment are lasers, mirrors and other components. Whether 2D or 3D laser scanner processing relief, its working principle is through the software will need to process the 3D model for slicing, and then control the laser on a complete piece of material layer by layer removal, to achieve three-dimensional laser engraving. However, their processing is very different.
The 2D laser scanner is used to process reliefs with a lifting table. During the process, the lift table system controls the focus of the 2D laser scanner at each layer of the laser removal material. This assembly not only greatly compresses the cost, but at the same time the 2D laser scanner calibration work is relatively easy and quick to start, suitable for beginners.
3D laser scanner processing relief process is: through the software control of the 3D laser scanner Z-directional dynamic axis and XY axis of the joint synergy. As the number of layers processed varies, the Z-directional dynamic axis moves back and forth in focus compensation to ensure the consistency of the light spot throughout the working process. In contrast, when 3D laser scanner is processing relief, the Z-axis and XY-axis are in full synergy, which can complete the backward and forward moving focus compensation at nearly microsecond level, without the limitation of external lifting table, with relatively higher efficiency and accuracy. 3D laser scanner is more inclined to industrialized products.
