Problems solved by technology

Usually, the shape memory effect needs to be artificially shaped under stimulus-driven conditions to trigger the shape memory effect. However, for some spatial structures and long-range applications, it is difficult to achieve folding deformation by artificial external force. In this case, self-deformation function becomes more important

[0038] A preparation method of a 3D printing non-shaped self-deforming shape memory smart material of the present invention, the method comprises:

[0039] Step 1: Design the structure of the material, and use Solidworks to model the material in 3D;

[0040] Step 2: Slice the model according to the design of step 1, and convert to generate STL format file;

[0041] Step 3: Input the STL format file into the 3D printing system, set the printing path and 3D printing parameters, and the cross angle between layers is 0°-180°;

[0042] Step 4: Using the fused deposition molding process, first restore the printing extrusion head and the bottom plate to the zero position, fine-tune the height of the extrusion head, and adjust the distance between the extrusion head and the bottom plate to be 0.2mm-0.6mm, so that the material can be printed in 3D. When pre-stretching the extruded filament, the limitation of the bottom plate or the adhesive layer allows the pre-stress to be preserved ...

Abstract

The invention discloses a preparation method of 3D printing non-shaped self-deformation shape memory smart material. The method includes step 1: designing the structure of the material, and using Solidworks to carry out three-dimensional modeling of the material; step 2: slicing the model according to the design Process, convert and generate STL format files; Step 3: Input the STL format file into the 3D printing system, set the printing path and 3D printing parameters, and the intersection angle between layers is 0°-180°; Step 4: Use the fused deposition modeling process, First, restore the printing extrusion head and the base plate to the zero position, fine-tune the height of the extrusion head, and adjust the distance between the extrusion head and the base plate to 0.2mm‑0.6mm, so that the material can be pre-stretched during 3D printing. , the limitation of the bottom plate or the adhesive layer allows the prestress to be preserved in the material, so that the material can fix the temporary shape; step five: printing; step six: heating the printed material to above the glass transition temperature; this preparation method can achieve high Accurate shaping and realizing multi-mode and diverse self-deformation.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to a preparation method of a 3D printing non-shaped self-deforming shape memory smart material. Background technique [0002] 3D printing, also known as additive manufacturing, is a kind of rapid prototyping technology. It is different from the traditional processing mode of raw material removal, cutting and assembly. Adhesive materials, a manufacturing method by layer-by-layer printing and stacking, have the advantages of saving materials, reducing production costs, shortening product development cycles, improving production efficiency, and having high precision. With the rapid development of 3D printing technology in recent years, the structural design of smart materials and the advantages of 3D printing can be better integrated, providing theory and technology for the design and manufacture of a new generation of smart materials. [0003] Shape memory polymer is a kin...
