Abstract

This invention belongs to the field of 3D printing technology, and particularly relates to a method and equipment for additive manufacturing of continuous carbon fiber irregular components. The manufacturing method includes the following steps: S1, constructing a support structure for shaping and support using an extrusion deposition method; S2, depositing an interface conditioning / reinforcing layer on at least a portion of the surface of the support structure, and depositing a main load-bearing area on the surface of the interface conditioning / reinforcing layer, wherein the melting temperature of the support structure is higher than the curing temperature of the main load-bearing area, and the melting temperature of the interface conditioning / reinforcing layer is lower than the curing temperature of the main load-bearing area; S3, after printing, subjecting the irregular component to thermosetting treatment, and after thermosetting, retaining or removing the support structure as needed. This invention achieves low-cost, simple, and efficient rapid prototyping while ensuring that the composite material has high fiber content and excellent interfacial bonding performance.
