Five-axis 3D printing device and molding method based on fused deposition modeling of metal wire

Abstract

The invention discloses a five-axis 3D printing device based on fused deposition modeling of a metal wire. The five-axis 3D printing device comprises a printing head, a liftable spindle, X-axis and Y-axis guide rails / sliding tables, a horizontal support, a vertical support, a printing base table and a chuck. The five-axis 3D printing device is mainly characterized in that (1) the vertical supportis mounted in the middle of the horizontal support, a vertical servo motor is mounted on the vertical support, and the printing base table or the chuck is mounted on a servo motor shaft (C-axis); (2)the two sides of the horizontal support are supported by vertical supporting columns, the horizontal support is connected with the vertical support through a bearing, one end of the horizontal supportis fixedly connected with a horizontal servo motor shaft (A-axis), the motor shaft is parallel to the X axis, and a horizontal servo motor and the horizontal support are mounted on the X-axis slidingtable; and (3) when the five-axis 3D printing device is used for printing a part, the part needs to be divided into a main body part and auxiliary parts, the main part is printed first and is taken down after being cooled, then the printing base table is replaced by the chuck, the main part is clamped on the chuck, and then the auxiliary parts of the part are printed with the main part as a basetable.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a five-axis 3D printing device and a molding method based on metal wire fusion deposition molding. technical background [0002] The 3D printing technology based on Fused Deposition Modeling (Fused Deposition Modeling, FDM) is one of the traditional printing technologies in the field of 3D printing. It is widely used by equipment developers because of its simple principle and easy implementation of printing materials in a molten state. And users are welcome. The printing materials that can be applied are widely distributed from low-cost plastic tubes to expensive metal wires. Especially in the field of metal 3D printing, compared with metal powder sintering technology (selectinglaser melting, SLM), the metal wire raw material used in 3D printing based on fusion welding method is easy to make, and the raw material consumption is low, which is a very promising devel...
