Abstract

The invention discloses a multifunctional additive manufacturing device and method for hollow filling composite wires. The multifunctional additive manufacturing device comprises a wire feeding pipe, the diameter of the upper section of the wire feeding pipe is uniform, the diameter of the lower section of the wire feeding pipe is gradually reduced, a heating block is arranged on the outer side of the diameter-gradually-reduced section of the wire feeding pipe, and a hollow base material is inserted into the wire feeding pipe in a penetrating mode; and the hollow base material extends into the wire feeding pipe through guiding of a wire guide wheel, the multifunctional additive manufacturing device further comprises an automatic filling device, the automatic filling device comprises a material mixing cavity, a feeding port and a discharging port are formed in the material mixing cavity, the discharging port is inserted into the junction of the diameter uniform section and the diameter gradually-reduced section of the wire feeding pipe in a penetrating mode, and a blade capable of splitting the side wall of the hollow base material is arranged at the upper part of the discharge port. According to the requirements of materials in different areas, the hollow base material can be filled with materials, and when the different areas are printed, the types and proportions of the materials are flexible and controllable.

Description

technical field [0001] The invention relates to the technical field of fusion deposition, in particular to a multifunctional additive manufacturing device and method for hollow-filled composite material filaments. Background technique [0002] At present, when processing composite materials, most of them can only process a certain type of composite material that has been prefabricated. It is difficult to perform real-time preparation and integrated processing of multiple composite materials, and the properties of the processed parts are relatively single. Usually, in order to meet the performance requirements of different regions, it is necessary to use high-performance composite materials for processing, which causes a great waste of high-performance materials. [0003] With the development of additive manufacturing technology, it provides a way of thinking for the real-time preparation and integrated manufacturing of various composite materials. The types of composite mate...
