Abstract

The invention discloses in-situ micro-glass-fiber reinforced polymer based 3D printing consumables as well as a preparation method and equipment thereof. Phosphate glass-ceramic and a polymer matrix are composited, so that the mechanical property of the FDM (frequency-division multiplexing) polymer based 3D printing consumables can be remarkably improved and nozzles cannot be blocked during printing; a static mixer is used for further mixing, the size of the phosphate glass-ceramic in a product is reduced, the mechanical property of a material is greatly improved through further extension by a traction device, and the contradiction between reinforcement of the 3D printing consumables and blockage of the nozzles is solved. The 3D printing consumables are prepared from the widely-sourced material, can realize continuous production easily and are low in cost and good in use effect; the preparation method is simple, and large-scale preparation is facilitated.

Description

technical field [0001] The invention relates to the field of material science, in particular to an in-situ micro glass fiber reinforced polymer 3D printing consumable and its preparation method and equipment. Background technique [0002] 3D printing-related technologies are increasingly being valued by developed countries in the world, and the country has made 3D printing-related technologies a key support area for the "Made in China 2025" plan. The development of 3D printing consumables technology is one of the keys to the popularization of 3D printing technology, and it is of great significance to improve the mechanical strength of 3D printing consumables. Glass fiber reinforced polymer materials are an effective way to improve polymer performance. The addition of glass fiber can increase the tensile strength and notched impact strength of polymers by more than 3 times. Glass fiber reinforced polymers are used in more and more fields. However, in the preparation process...
