3D Printing
3D printing, also known as additive manufacturing, is a technology that manufactures three-dimensional objects by stacking materials layer by layer. The core principle is "layered manufacturing, layer by layer stacking", similar to the process of triple integration of cylindrical coordinates in advanced mathematics. The 3D model is cut into a series of "thin slices" of a certain thickness, and the 3D printing equipment manufactures each layer of "thin slices" from bottom to top, and finally stacks them to form a three-dimensional solid part
