Embodiment Construction

[0034] Below in conjunction with specific embodiment, further illustrate the present invention.

[0035] like image 3As shown, the motion device adopts the gantry structure, and this type of motion device can complete three-dimensional space motion with low precision requirements. Considering that the accuracy requirements of the printer are not very high, it is more economical to choose the gantry structure. The nozzle bracket 20 is installed on the X-direction movement component, and the nozzle bracket 20 moves along the X direction driven by the X-direction movement component. The X-direction movement component is connected with the Z-direction movement component. The platform 12 is connected with the Y-direction movement assembly, and the platform 12 moves along the Y-direction under the drive of the Y-direction movement assembly.

[0036] The Y direction movement assembly of the Y direction movement assembly includes a Y direction belt transmission mechanism and a Y gu...

Abstract

The invention discloses a novel 4D printing system. The device comprises three major components including a motion device, a sprayer device and a feeding device. The motion device is of a gantry type structure and can drive a sprayer to flexibly move in the three-dimensional space. The feeding device is formed through integration of a screw extrusion device, a reeling shaft and an air pump. The sprayer device is divided into two layers including an inner structure and an outer shell. Under driving of a motor, the inner structure can rotate relative to the outer shell, and accordingly butt joint of different discharging ports and the outer shell sprayer can be achieved. By means of the device, constant switching printing of different active materials on a single device can be achieved, the printing time is saved, and the printing efficiency is improved; and meanwhile, due to a single-spraying-port structure, the printing precision is guaranteed, and mechanism redundancy is reduced.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a 4D printing device for printing active materials. Background technique [0002] 4D printing products made of active materials with the functions of "self-assembly, self-repair, and self-folding" are shining in many fields. The smart products manufactured by it get rid of the limitations of traditional electromechanical structures, and can be lighter and more flexible. The compact form completes advanced functions such as self-assembly, self-healing, and self-deformation, so it has greater flexibility. This advantage has great potential in many fields. For example, in the military field, 4D printing products can complete the change from two-dimensional to three-dimensional shape, which greatly saves the space occupancy rate of military equipment during transportation; in the field of soft robots, active The mechanical arm with the skeleton material can realize mo...
