Working principle of 3SP laser scanning

The EnvisionTEC 3SP series 3D printer uses groundbreaking 3SP technology to print high-precision parts in STL files, without being limited by geometric complexity. 3S refers to Scan, Spin, and Selectivity, which means that the laser head scans at a constant speed along the X-axis, and the Y-axis moves horizontally through selective light treatment and marking by a rotating light mirror, thus quickly curing the liquid photosensitive resin. The principle is to focus light of a specific wavelength and intensity on the surface of the light cured material, cure the liquid material, and complete the curing of one layer. Then, the lifting platform moves the height of one layer in the vertical direction, and solidifies another layer. In this way, the layers are stacked to form a three-dimensional solid model. In general, 3SP technology has a faster printing speed than SLA technology by using a horizontal method rather than a vertical one.

The 3SP 3D printer is a masterpiece produced by the globally renowned 3D printing company EnvisionTEC in Germany. It uses the groundbreaking 3SP technology (Scan Scan, Spin Rotation, and Selective Photocure) to print high-precision parts from STL files without being limited by geometric complexity. Used to support rapid direct manufacturing with low-cost and high-resolution solutions. The 3SP series has installed all relevant software to ensure automatic generation of supporting components and perfect model production.
