specific Embodiment

[0144] 1. Create a 3D model, save the model as an STL file format, and slice the file.

[0145] 2. Prepare the printing paste required for printing, and add the printing paste into the barrel 2 after preparation.

[0146] 3. Through the programming and setting of the computer control system 10, the trajectory of the nozzle rotation mechanism, the magnitude of the pressurization and the rotation of the rotary drive device can be controlled, and the sliced ​​three-dimensional model STL file can be input for printing.

[0147] 4. The connector 3 is connected to the barrel 2 in rotation, and the pressurizing device 1 applies a thrust to the printing slurry in the barrel 2 through the hose, so that the printing slurry is squeezed from the barrel 2 into the nozzle rotation mechanism, and then squeezed out by the nozzle 5. out. The nozzle 5 can make a circular motion relative to the barrel 2. When the nozzle 5 rotates, the printing slurry in the nozzle can generate a circumferential...

Abstract

The invention discloses a composite material direct-writing forming 3D printing method and device with controllable reinforcement phase arrangement. The device comprises a three-dimensional movement mechanism; the slurry conveying mechanism comprises a charging barrel used for loading printing slurry, a pressurizing device, a nozzle rotating mechanism and a computer control system; the printing slurry is a semi-fluid or paste mixture and comprises a base material, a reinforcing phase and an auxiliary reagent system; the pressurizing device is used for providing thrust for extruding the printing slurry; the nozzle rotating mechanism is arranged at the bottom of the charging barrel; and the computer control system is used for controlling the three-dimensional movement mechanism, the slurry conveying mechanism and the nozzle rotating mechanism. The nozzle rotating mechanism is controlled to drive the nozzle to rotate, so that printing slurry in the nozzle can generate a circumferential shear stress field, the printing slurry can generate a shear rheological effect during extrusion, a reinforcing phase is spirally arranged along a slurry printing path and is controllable in positioning, the overall or local mechanical property of a printed product is improved in a targeted manner, and a composite material component with special mechanical properties is prepared.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a 3D printing device for composite material direct-writing molding with controllable reinforcement phase arrangement. Background technique [0002] Compared with traditional materials, reinforced composite materials have the characteristics of excellent mechanical properties, small specific gravity, wear resistance, high temperature resistance, and low thermal expansion coefficient. It is widely used in the preparation of key structural components in aircraft, automobiles and precision machinery. The preparation of composite components with light weight, high strength and toughness, and impact resistance can improve their comprehensive performance and service life, and reduce resource and energy consumption. Composite components that meet the above properties usually have complex cross-scale gradient composite structures. [0003] Direct-write molding 3D printing is a common ...
