Continuous fiber reinforced composite material 3D printer sprayer device of integrated structure

Abstract

The invention belongs to the field of 3D printer structure design and relates to a continuous fiber reinforced composite material 3D printer sprayer device of an integrated structure. As for the device, composite material fiber yarn which is well treated in advance is integrally printed through a matrix / supporting material printing device and a fiber printing device, specifically, the composite material fiber yarn is formed by wrapping the periphery of fiber yarn (such as glass fibers and carbon fibers) with a thermoplastic material (such as PLA, ABS and nylon), the matrix / supporting materialprinting device undertakes the matrix and supporting material printing task, the fiber printing device undertakes the composite material fiber yarn printing task, and in the whole printing task, the matrix / supporting material printing device and the fiber printing device perform printing alternately on schedule till completing printing.

Description

technical field [0001] The invention belongs to the field of design and manufacture of 3D fusion printers. It is a continuous fiber reinforced composite material 3D printer nozzle device with an integrated structure. Composite fiber filaments (hereinafter all named as such), composite fiber filaments are made of fiber filaments (such as glass fibers, carbon fibers, etc.) wrapped with thermoplastic materials (such as PLA, ABS and nylon, etc.), where the matrix / support material printing device Consisting of a remote extrusion head, the fiber printing setup consists of feeding, heating, clamping and cutting sections. Background technique [0002] At present, the 3D molding technologies in the domestic and foreign markets mainly include: metal powder direct laser sintering, selective laser sintering, 3D printing bonding molding and fused deposition modeling (FDM). Among them, the most widely used one is Fused Deposition Modeling (FDM). The printing materials currently used in C...

AI Technical Summary

Problems solved by technology

At present, domestic 3D printers have not seen detailed reports that can print composite materials; and although there are already 3D printers that can print composite materials in the United States, the printing nozzles are relatively large and heavy, and because the cutting and printing devices are separated structures, Therefore only larger objects can be printed
