Embodiment Construction

[0021] will now be combined Figure 1-12 , to fully describe the technical solution of the present invention. The following descriptions are only some implementation examples of the present invention, not all of them. Based on the implementation cases in the present invention, all other implementation cases obtained by those skilled in the art without creative work fall within the protection scope of the present invention.

[0022] Such as Figure 1-12 As shown, the present invention discloses a FDM spinning mechanism design for 3D printing of complex workpieces. This mechanism consists of two parts: the wire feeding system and the wire discharging system. The wire feeding system is connected to the control system, and the lower end is connected to the wire discharging system. Under the joint action of the wheel and the feeding gear, it is forced to move downward, and this process realizes the continuous supply of printing raw materials.

Abstract

The invention discloses an FDM spinneret mechanism for 3D printing of a complex workpiece. The FDM spinneret mechanism comprises a wire feeding system mounted above and a wire outlet system fixed below the wire feeding system; in the wire feeding system, an L-shaped connecting piece connected with a throat pipe is optimized, a fan speed governor is installed on the side of the connecting frame, and a lengthened throat pipe is designed in the wire outlet system to print the complex workpiece. The spinneret mechanism can effectively solve the problem that an FDM three-dimensional printer printsthe complex workpiece as well as the problem existing in a current three-dimensional printing that a nozzle is blocked due to the fact that wire materials are prone to thermal expansion. According tothe FDM spinneret mechanism for 3D printing of the complex workpiece, the application range of FDM three-dimensional printing is expanded while the printing efficiency and the printing product precision are improved, and higher economic benefits are achieved.

Description

technical field [0001] The invention relates to an FDM spinning mechanism for 3D printing of complex workpieces, and belongs to the technical field of equipment components in the field of 3D printing. Background technique [0002] Fused Deposition Modeling (Fused Deposition Modeling, FDM) 3D printing technology is one of the traditional technologies in the field of 3D printing. It is welcomed by many users because of its easy-to-implement manufacturing method of fused layer-by-layer accumulation molding, and can be used to print various physical models. Even utility artifacts. The spinneret is the core component of this type of printing equipment. At present, the traditional spinneret combined with a short throat and a large heating block is usually used in the market. Since this spinning mechanism easily interferes with the workpiece, it is only suitable for 2.5-axis printing process, and cannot be applied to multi-axis unsupported 3D printing of complex workpieces. The u...
