Problems solved by technology

The deformation process of this type of 4D printing technology often takes a long time, it is difficult to achieve rapid and timely deformation, and it is often difficult to control the external conditions of the thermal field and water environment. These defects largely limit 4D intelligent printing. The further advancement of technology into reality

Embodiment 1

[0026] Step 1: Add 5g of iron powder to 5g of Dow Corning SE1700, and mix evenly to form the magnetic ink to be printed.

[0027] Step 2: Put the ink into the printer barrel, set the butterfly model, slice it, generate the printing path, and print according to the butterfly path, such as figure 1 shown.

[0028] Step 3: Heat and cure the printed butterfly at 100°C for 1 hour.

[0029] Step 4: Apply an externally changing magnetic field excitation to the heat-treated butterfly, such as figure 2 As shown, realize the movement of the butterfly in the fourth dimension, such as image 3 shown.

Abstract

The invention discloses application of a magnetic elastic material to 4D printing, and belongs to the technical field of composite magnetic materials and 4 D printing. A magnetic element and a flexible substrate material form compound slurry, then the compound slurry is printed into a three-dimensional structure through direct ink writing, the three-dimensional structure has the structure-variablecharacteristic along with the fourth dimension time change under the effect of an applied magnetic field, and then 4D printing is achieved. By utilizing a 4D printing technology, the printed three-dimensional structure can quickly deform under the effect of the applied magnetic field, and non-touch regulation of the three-dimensional structure is achieved.

Description

Technical field: [0001] The invention relates to the technical field of composite magnetic materials and 4D printing, in particular to the application of a magnetoelastic material in 4D printing. Background technique: [0002] With the development of 3D printing technology, its research in the fields of metals, ceramics, plastics, and biology has become increasingly in-depth, and 4D printing technology has also attracted widespread attention in the world. 4D printing technology refers to the use of material shape memory or recoverable properties to endow 3D printed objects with time changes in the fourth dimension. The development of this technology will enable the manufacture of intelligent materials and promote the further application of intelligent sensor devices. [0003] However, the current 4D printing technology can use the thermal field or the water environment as an external stimulus, use material expansion, distortion, etc. to generate internal stress deformation,...
