Abstract

The invention provides a 3D printing preparation method of a polymeric gradient material. The method comprises the following steps: (1) preparing inorganic components, polymers and other raw materials; (2) establishing a three-dimensional computer sketch map of the polymeric gradient material, performing slicing processing, and establishing a scanning path; (3) calculating the component ratios at different positions; (4) setting the corresponding printing parameters; and (5) starting printing equipment for performing 3D printing, simultaneously injecting the inorganic particles and polymers into the printing head, heating, mixing, and printing and forming according to the set track and speed. The method disclosed by the invention has the advantages that the raw material component ratios at different positions are controlled by the computer, so that gradient distribution of the components is really realized. The 3D printing technology is a material increase manufacturing method, and compared with the traditional process, the method disclosed by the invention has the advantage that the raw materials are saved.

Description

technical field [0001] The invention relates to a 3D printing preparation method of a polymer-based gradient material, belonging to the field of material preparation. Background technique [0002] Gradient functional materials are different from homogeneous materials and composite materials. It selects two (or more) materials with different properties, and continuously changes the composition and structure of the two (or more) materials to make the interface disappear. The performance of the material changes slowly with the composition and structure of the material, forming a gradient functional material. [0003] From the perspective of material combination, gradient materials can be divided into metal / alloy, metal / non-metal, non-metal / ceramic, metal / ceramic, ceramic / ceramic, metal / polymer, ceramic / polymer and other combinations. Therefore, a variety of materials with special functions can be obtained. [0004] Polymer-based composite material is a kind of multi-phase sol...
