Double-printing-head 3D printer motion structure

Abstract

The invention discloses a double-printing-head 3D printer motion structure which comprises a first printing head, a second printing head, a first X-direction driving mechanism, a second X-direction driving mechanism, a Y-direction driving mechanism, a first X-direction transmission mechanism, a second X-direction transmission mechanism and a Y-direction transmission mechanism. The first X-direction driving mechanism is used for driving the first printing head to move in the X direction through the first X-direction transmission mechanism. The second X-direction driving mechanism is used for driving the second printing head to move in the X direction through the second X-direction transmission mechanism; the Y-direction driving mechanism is used for driving the first printing head and the second printing head to move in the Y direction through the Y-direction transmission mechanism. The double-printing-head 3D printer motion structure can reduce the situation that the printing precisionis reduced due to dislocation caused by incoordination of X-axis movement and Y-axis movement, is suitable for long-time printing, and facilitates improvement of the printing success rate.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a motion structure of a double print head 3D printer. Background technique [0002] FDM rapid prototyping technology is based on the digital model file, heating and melting the linear hot-melt material, and at the same time, under the control of the computer, the nozzle selectively extrudes the material on the workbench according to the cross-sectional profile information Cool and solidify. After one layer of molding is completed, the workbench is lowered to a layer height and then the next layer is formed until the entire solid shape is formed. [0003] In the motion structure of the independent dual-print head 3D printers currently on the market, two sets of independent print heads are usually mounted on the X sliding module, and then the entire X module is mounted on the Y sliding module to drive the 3D printer head in X, Y. direction of movement. When the motion struct...

Problems solved by technology

When the motion structure of such a dual-print head 3D printer moves at the same time on the X and Y axes, due to the different loads on the X and Y axes, a greater inertial force will be generated on the Y axis, resulting in uncoordinated movement of the X and Y axes and resulting in misalignment, which affects Accuracy of prints

Especially when the 3D printer works for a long time, the disadvantages are particularly prominent, and even lead to printing failure
