3D is the abbreviation of "3 Dimensions" in English. Chinese refers to three dimensions, three dimensions, and three coordinates, namely length, width, and height.

In other words, it is three-dimensional. 3D is the concept of space, which is a space composed of three axes: X, Y, and Z. It is relative to a plane (2D) with only length and width.

According to scientific conjecture, people originally live in a four-dimensional three-dimensional space (plus a time dimension). The world perceived by the eyes and body is three-dimensional (time is fictitious), and has rich colors, luster, and surfaces.

, materials and other appearance textures, as well as the ingenious and intricate internal structure and dynamic movement relationship of space and time.

Extended information: Application of 3D technology The application of 3D technology is popularized, and it is oriented to the development and production of cultural and artistic products with visual expressions such as film and television animation, animation, and games, and it is oriented to the design of physical products such as cars, airplanes, home appliances, and furniture.

and production, as well as virtual reality simulation and simulation for human-environment interaction.

In the development and production process of modern industrial products, the outstanding advantage of 3D is that it can maximize product simulation design and user communication, solve errors and demand changes as early as possible in the design stage, shorten the product development cycle and reduce production costs.

, enhance the enterprise's market competitive advantage.

3D printing technology is based on computer three-dimensional design models, and uses laser beams, hot melt nozzles, etc. to stack special materials such as metal powder, ceramic powder, plastic, and cell tissue layer by layer through software layered discretization and CNC molding systems.

Bonding, and finally overlay molding to create a physical product.
