3D printer with multi-directionally movable nozzles

Abstract

The invention discloses a 3D printer with multi-directionally movable nozzles. The 3D printer comprises a bracket (1), a pedestal (2), an X / Y direction horizontal feeding device (3), a first support platform (4), a second support platform (5), a raw material unit and a plurality of nozzles (6). The nozzles (6) are fixedly mounted on the second support platform (5), the second support platform (5) is mounted below the X / Y direction horizontal feeding device (3), the X / Y direction horizontal feeding device (3) is mounted below the first support platform (4), the first support platform (4) slides up and down along a guide rail on the inner wall of the bracket (1), and the nozzles are connected to the raw materials unit respectively. The 3D printer provided by the invention realizes movement in the X and Y directions through the X / Y direction horizontal feeding device, achieve movement in the Z direction by the first support platform, can realize multi-directional movement of the nozzles without fatigue loss of connecting pieces caused by frequent movement of the nozzles, and can improve the precision of printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printer whose spray head can move in multiple directions. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital files, using powder or curable materials, and manufacturing products by layer-by-layer printing. It is in sharp contrast to the subtractive manufacturing technology used in traditional manufacturing. In contrast, 3D printing is an additive manufacturing technology that forms the final product by superimposing layers of materials. [0003] The more mainstream technologies in 3D printing technology include: Fused deposition modeling technology (Fused deposition modeling, FDM), stereolithography technology (Stereolithography, SLA), selective laser sintering technology (Selective lasersintering, SLS), three-dimensional printing technology (3D printing, 3DP) etc. [0004] The FDM printe...

AI Technical Summary

Problems solved by technology

3DP technology can realize color printing and can use a variety of raw materials, but the products produced by it generally have rough surfaces and relatively poor precision

[0008] In 3D printing technology, in order to make the printed items have a better user experience, it is often necessary to move the nozzle for multi-directional printing, but the frequent movement of the nozzle will lead to fatigue wear of the connecting parts. If it cannot be maintained in time, it will cause printing The accuracy error of
