Description

technical field [0001] The invention relates to an additive manufacturing technology, in particular to a continuous fiber solidification extrusion device for additively manufacturing ceramic composite materials. Background technique [0002] Additive Manufacturing (AM) is a method developed in the 1990s for the rapid construction of complex models. Contrary to traditional material removal techniques (such as milling, cutting or drilling), additive manufacturing is based on the discrete-accumulation principle, according to the three-dimensional model to obtain discrete two-dimensional contours, by adding liquid-based materials, solid sheet materials or powder Materials are taken and cured to build parts, a "top-down" manufacturing approach. The biggest advantage of additive manufacturing technology is that it can quickly manufacture parts with specific geometric shapes directly through the 3D model data of the parts, without any molds, fixtures and cutting tools, which great...

Problems solved by technology

However, ceramic materials have high hardness and brittleness, and are difficult to cut. During the cutting process, they are characterized by high cutting force, severe tool wear, and easy cracks. They are one of the most difficult materials to machine, especially when ceramic materials are used in aviation. In the aerospace, medical and other fields, traditional techniques are difficult to process complex precision ceramic parts, which severely limits the wide application of ceramic materials. The emergence of additive manufacturing technology makes the manufacture of precision ceramic parts possible.

The direct forming of ceramic materials has become a research hotspot and one of the important development directions of additive manufacturing technology, but the problem of high brittleness of formed parts still needs to be solved urgently
