Spatial structure and printing method suitable for continuous fiber 3D printing

The invention provides a spatial structure suitable for continuous fiber 3D printing. The spatial structure comprises a plurality of parallel lattice structures and bearing surfaces vertical to the adjacent lattice structures. Each lattice structure is composed of a rod-like supporting rod, and each bearing face is composed of a rod-like bar and a bearing region. Meanwhile, the invention providesa printing method suitable for continuous fiber 3D printing. By means of the spatial structure suitable for continuous fiber 3D printing, a lattice structure and 3D printing are combined, so that themanufactured material has the characteristics of being light in weight, high in bearing capacity and stable in mechanic bearing capacity on the structural unit, and is high in manufacturing speed, lowin technical difficulty and free of precision molds, and the manufacturing period is shortened. 本发明提供了种适合连续纤维3D打印的空间结构，此空间结构包含若干个平行的网格结构和垂直于相邻网格结构的承载面。每个网格结构由棒状支杆组成，每个承载面是由棒状杆和承载区组成。同时本发明提供了种适合连续纤维3D打印的打印方法，利用本发明的3D打印方法打印的本发明的
