4D printing device and system

Abstract

The invention provides a 4D printing device and system, and relates to the technical field of 3D printing. The 4D printing device comprises a base, a printing platform, a stand column, a sliding block, a moving part, a connecting plate and a printing nozzle. The printing platform and the stand column are arranged on the base, the sliding block is arranged on the stand column, the moving part is arranged on the sliding block, one end of the connecting plate is movably connected with the moving part to form a cantilever beam structure, and the other end of the connecting plate is hinged to the printing nozzle. By means of cooperation of printing platform rotation around the axis of the printing platform, connecting plate movement in the radial direction of the printing platform, sliding block movement in the vertical direction of the stand column and printing nozzle rotation relative to the connecting plate, the 4D printing function under the polar coordinates mode is achieved. The printing device, particularly on a printing rotating part, is higher in precision, higher in efficiency and capable of effectively improving the printing precision of the cambered surface and the curved surface. The printing part structure has the reconfigurability, and print size range adjustment is flexible. The overall composition is simple, the flexibility is better achieved, an open structure is formed in the printing area, and picking and placing of printed matter are facilitated.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a 4D printing device and system. Background technique [0002] At present, most of the working structures of 3D printers adopt spatially orthogonal mechanisms, that is, the traditional 3D printing system is based on the Cartesian coordinate system to establish the motion mode, and the structural shape of the 3D printing system designed based on this coordinate system is usually a cube. , occupying a larger space. However, the current 3D printing system based on the polar coordinate system has a relatively complicated mechanical structure, which forms a certain barrier to the space of the printing area, making it inconvenient to pick and place the printed object after printing. [0003] In addition, the angle between the printing nozzle and the base plane of the traditional 3D printing system is always in a fixed state. Although it is easy to realize, it does not take...
