Abstract

The invention discloses a fusion-deposition 3D printer. The fusion-deposition 3D printer comprises a shell, a lifting mechanism and a composite extruding mechanism, wherein the lifting mechanism is mounted in the shell; the composite extruding mechanism comprises a machine cylinder, a screw rod and a long-fiber conveying pipe, a feeding pipe communicated with a material cavity of the machine cylinder is arranged on the side wall of the machine cylinder, the screw rod is rotatably mounted in the material cylinder and is provided with a mounting channel, and the upper and lower ends of the screw rod are communicated through the mounting channel; the long-fiber conveying pipe is inserted into the mounting channel and is provided with a conveying channel for conveying long continuous fibers; the conveying channel, the mounting channel and the material cavity are sequentially communicated. The invention further discloses a printing method of the fusion-deposition 3D printer. According to the fusion-deposition 3D printer and the printing method thereof, the long continuous fibers and printing materials packing the long continuous fibers are synchronously extruded to a working platform, so that the strength and surface flatness of a printed product are improved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to 3D printing technology, in particular to a fusion deposition 3D printer and a printing method thereof. Background technique [0002] 3D printing is a widely used rapid prototyping technology at present. The principle of its forming process is: first establish a computer 3D model of the target part, and then use software to process the 3D model in layers and slices to obtain the data information of each processing level. Under the control of the computer, the laminated additive manufacturing is carried out according to the information at the slice level to complete the manufacturing of the target processing. The advantage of 3D printing is that it is not limited by the complexity of the shape of the part, does not require any tooling and molds, is fast and efficient, and can realize the automatic manufacturing of free-form entities, which is receiving more and more attention. [0003] A fused deposition 3D printer is one of the...
