Preparation method and device of 4D printing material

Abstract

The invention discloses a 4D printing material preparation method and device.The 4D printing material preparation device comprises a filtering device, the filtering device comprises a first support, a vertical rod moving in the vertical direction penetrates through the top of the first support, a sliding base moving in the horizontal direction is slidably connected to the top of the vertical rod, and a filtering box is fixedly connected to the top of the sliding base; a fourth connecting rod is rotationally connected to one side of the sliding base, a movable frame is fixedly connected to the bottom of the vertical rod, and a fixing plate is connected to the bottom of the first support. According to the device, hydrogen absorption niobium-titanium alloy powder with the particle size being 50-300 microns after being stirred and mixed enters the filter box through the first connecting pipe, niobium-titanium alloy powder with the average particle size being smaller than 120 microns is obtained after filtering, then the niobium-titanium alloy powder enters the collecting box through the second connecting pipe, the stirring device and the filter device are combined for use, and the stirred powder directly enters the filter device; and the filtered powder directly enters the collecting box, so that the process continuity is improved, the process steps are reduced, and the working efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of 4D printing, in particular to a preparation method and device of a 4D printing material. Background technique [0002] 4D printing, to be precise, is a material that can be deformed automatically. Just put it in water, without connecting any complex electromechanical equipment, it can be automatically folded into a corresponding shape according to the product design. The uniqueness of 4D printing That is, there is one more "D" than 3D printing, that is, the latitude of time, which means that in addition to moving around on the X, Y, and Z axes, the material will also change its shape or function over time due to changes in external conditions. Due to the effects of mechanical force, temperature, expansion, magnetic field, etc., 4D printing materials can reconfigure themselves, thereby changing color, shape and performance. The main materials of existing 4D printing technology are limited to organic materi...

[0002] 4D printing, to be precise, is a material that can be automatically deformed. Just put it in water, without connecting any complicated electromechanical equipment, it can be automatically folded into the corresponding shape according to the product design. The uniqueness of 4D printing The reason is that there is one more "D" than 3D printing, which is the time latitude, which means that in addition to tossing and moving on the X, Y, and Z axes, the material will also change its shape or function over time due to changes in external conditions. Due to the effects of mechanical force, temperature, expansion, magnetic field, etc., 4D printing materials can reconfigure themselves, thereby changing the color, shape and performance. The main materials of existing 4D printing technology are limited to organic materials, but the high temperature resistance of organic materials is poor. Therefore, the present invention provides a niobium-titanium alloy as a 4D printing material. Compared with organic materials, it has good high temperature resistance and corrosion resistance. The combined device with filtration can sieve niobium-titanium alloy powder to improve the work efficiency of 4D printing material preparation
