Zusammenfassung:	The present invention relates to the field of composite material design and manufacture, and disclosed in the present invention are a continuous fibre multi-layer honeycomb sandwich plate and an integrated forming method therefor. The multi-layer honeycomb sandwich plate comprises a lower panel, honeycomb cores, an intermediate panel and an upper panel, wherein the upper panel and the lower panel are respectively located at an upper end and a lower end of the honeycomb sandwich plate, the intermediate panel is located between two layers of the honeycomb cores, and the sandwich plate is integrally formed, by 3D printing, by means of using a continuous fibre composite material. During a manufacturing process, a continuous fibre and a matrix material are continuously extruded and formed after being heated by a spray head of an apparatus; by means of the spray head, the lower panel of the honeycomb sandwich plate is formed on a surface of a working table, then, the honeycomb cores are formed on the lower panel, s
