Embodiment Construction

[0035] The detailed content of the present invention and its specific implementation will be further described below in conjunction with the accompanying drawings.

[0036] see Figure 1 to Figure 5 As shown, the integrated printing device and printing method of the continuous fiber embedded material of the present invention, a polymer cylinder with holes is prefabricated into a filament rod, and the continuous fiber is passed through the hole of the filament rod, and the filament rod is formed by a compact Clamped in the center of the filament forming tube, the push rod located at the upper end of the filament forming mechanism continuously pushes the filament forming rod downward. The filament forming rod passes through the heating zone, and the molten polymer flows down and wraps on the surface of the continuous fiber, and finally flows from the bottom of the filament forming tube The forming wire comes out, and the forming wire passes through the measuring and shearing mec...

Abstract

The invention relates to an integrated printing device and printing method of a continuous fiber embedded material, and belongs to the technical field of function material 3D printing. A polymer cylinder filamentation stick with a hole is preformed, and a continuous fiber penetrates through the hole of the filamentation stick; the filamentation stick is tightly clamped in a filamentation barrel; apush rod pushes the filamentation stick downwards; the filamentation stick passes through a heating area; molten polymer flows downwards to wrap the surface of the continuous fiber; finally, a formedwire comes out from the bottom of the filamentation barrel; the formed wire passes through a measuring and shearing mechanism, is shorn when the diameter does not meet the requirement and directly enters a feeding mechanism when the diameter meets the requirement; the feeding mechanism unceasingly feeds the formed wire downwards; and the formed wire is fed into a printing head part, and printingis achieved. The integrated printing device and printing method have the advantages that adhesiveness between the fiber and the polymer is good, local accumulation of the continuous fiber cannot be generated, formed wires of different diameters can be obtained through printing according to requirements, and printing of continuous fiber embedded type high-melting-point polymer is achieved.

Description

technical field [0001] The present invention relates to the technical field of 3D printing of functional materials, in particular to an integrated printing device and printing method for continuous fiber embedded materials, and is an integrated printing method and device for continuous fiber embedded materials that are suitable for high melting point materials at the same time. Problems of continuous fiber distribution and bonding between dissimilar materials are solved, providing solutions for non-industrial environments. Background technique [0002] Fused deposition is the most commonly used additive manufacturing technique and is currently the only additive manufacturing method for high-melting, high-performance polymers. [0003] Continuous fiber-embedded functional materials have excellent mechanical properties (such as modulus, strength), potential recycling and lighter structures, making them have a wide range of application prospects, and are gradually replacing ord...
