3D printing (also known as additive manufacturing) is a technology that builds three-dimensional objects by stacking materials layer by layer. Compared to traditional subtractive manufacturing (such as cutting and grinding), it can directly generate complex structures based on digital models, offering significant advantages in design freedom, material utilization, and personalized customization. The following sections provide … Read more
