Abstract
The invention relates to the technical field of dielectric functional gradient material manufacturing, and provides a dielectric functional gradient 3D printing wire manufacturing device and method. A dielectric constant of a wire to be printed is arranged in a control mechanism of the manufacturing device, and the control mechanism controls the feeding proportion of feeding boxes in a feeding mechanism according to the dielectric constant, that is, the control mechanism at least controls the mixing proportion of a plastic base material and a dielectric filler, so that after being processed by a mixing processing mechanism, the wire to be printed can be printed. The dielectric constant of the prepared wire meets the requirement, the control mechanism can change the mixing proportion between the base material and the filler by adjusting the adjusting structure, the dielectric constant values of all sections of the finally manufactured wire are different, the control mechanism adjusts the adjusting part according to the dielectric constant gradient distribution data of the needed wire, and the control precision of the wire is improved. The required wire material with gradient dielectricity can be prepared, and the required functionally graded material can be obtained after the wire material is used in the field of 3D printing.
Description
technical field [0001] The present invention relates to the technical field of dielectric functionally graded materials, in particular to a device and method for manufacturing dielectrically graded 3D printing filaments. Background technique [0002] Functionally graded material (Functionally Graded Material, FGM) combines materials with different characteristics to make the material characteristics present non-uniform gradient changes at different spatial positions inside the material, thereby alleviating local stress concentration and improving the overall performance of the material. In recent years, some scholars have introduced this concept into the electrical field, and proposed the concept of dielectric functionally graded materials, that is, by regulating the distribution of dielectric properties (conductivity / permittivity) of insulating materials, the electric field distribution can be adjusted to alleviate the local The purpose of reducing the flashover voltage by ...
