Embodiment Construction

[0019] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0020] see figure 1 Shown is a schematic structural view of an extrusion device applied to a fused deposition modeling high-speed 3D printer of the present invention.

[0021] In one embodiment, an extrusion device applied to a fused deposition modeling high-speed 3D printer includes an extrusion nozzle 1, a wire feeding module and a stepping motor 2, and the wire feeding module is driven by the stepping motor 2 Next, the ABS or PLS printing wire 4 is sent to the extrusion nozzle 1 and extruded. The wire feeding module and the extrusion nozzle 1 are printing traveling mechanisms. In the case of using the flexible shaft 3 to connect the stepper motor 2 and the wire feeding module, the stepper motor 2 can be arranged on the bottom of the 3D printer, and the printing traveling mechanism can be arranged on the 3D printer the top of. The outpu...

Abstract

The invention relates to an extrusion device applied to a fused deposition modeling high speed 3D (Three Dimensional) printer, which belongs to the technical field of 3D printing. The extrusion device comprises an extrusion nozzle, a wire feeding module and a stepping motor, wherein the wire feeding module conveys a printing wire to the extrusion nozzle for extruding under the drive of the stepping motor. The wire feeding module and the extrusion nozzle form a printing travelling mechanism, the stepping motor is fixedly arranged on the high speed 3D printer, an output shaft of the stepping motor is connected to the wire feeding module via a motor driving flexible shaft, and the stepping motor does not follow up the motion of the printing travelling mechanism, so that the whole weight of the printing travelling mechanism is reduced effectively and the printing travelling mechanism can run fast, and simultaneously the extrusion precision and the even extrusion pressure of the extrusion device are ensured. The extrusion device which is applied to a fused deposition modeling high speed 3D printer and provided by the invention has a simple structure and a convenient use-pattern and is low in cost.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to the technical field of fused deposition modeling high-speed 3D printers, and specifically refers to an extrusion device applied to fused deposition molding high-speed 3D printers. Background technique [0002] Fused deposition, also known as fused filament deposition or selective cladding of filamentous materials, is a new type of 3D printing method. It heats and melts the filamentary hot-melt material. At the same time, under the control of the computer, the three-dimensional nozzle selectively coats the material on the worktable according to the information of the cross-section profile, and forms a layer of cross-section after rapid cooling. Then repeat the above process, continue to meltblown deposition, until the entire solid shape is formed. [0003] Due to its many types of molding materials, high strength, high precision, good surface quality, easy assembly, pollution...
