Abstract

The invention discloses a multifunctional additive manufacturing device and method for hollow-filled composite material wire, which includes a wire feeding tube, the diameter of the upper section of the wire feeding tube is uniform, the diameter of the lower section is tapered, and the diameter of the wire feeding tube is tapered. A heating block is arranged on the outer side of the wire feeding tube, and a hollow base material is interspersed in the wire feeding tube. The mixing chamber is provided with a feed port and a discharge port, the discharge port is interspersed at the junction of the uniform diameter section and the tapered diameter section of the wire feeding tube, and the upper part of the discharge port is provided with a hollow base A blade that cuts through the sidewall of the wood. The invention can fill the interior of the hollow base material with materials according to the requirements of materials in different areas, so as to achieve flexible and controllable material types and ratios when printing different areas.

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...
