Abstract
The utility model discloses a 3D platform of a 3D printer. The 3D platform comprises a mounting frame, the printing platform in the mounting frame, and a 3D printing head above the printing platform, wherein the printing platform is provided with a Z-axis moving device driving the printing platform to move along the Z axis, an X-axis moving device driving the 3D printing head to move along the X axis, and a Y-axis moving device driving the X-axis moving device to move along the Y axis. The 3D platform adopts two transmission modes, namely feed screw nut transmission and synchronous belt transmission. The feed screw nut transmission has the advantages of good stability, high accuracy, small noise, and capacity of bearing high load, thus being used for transmission in the Z axis and Y axis directions. A synchronous belt is light and cheap, has an accurate transmission ratio and no slip frequency, can obtain a constant speed ratio, is stable in transmission, can absorb certain vibration, is low in noise, large in transmission ratio range, and high in transmission efficiency, and can greatly improve the position accuracy of the printing head when being used for transmission of the 3D printing head along the X axis.
