Problems solved by technology

For example, in the laminated entity manufacturing technology, the ceramic film prepared by casting method is used as raw material to produce ceramic parts, which has low strength and complicated subsequent processing; while the fused deposition molding technology mixes ceramic powder and organic binder, and then extrudes Silk, sintering, the shrinkage rate of the produced ceramic parts is relatively large and the removal process of the organic binder is complicated
Other rapid prototyping technologies such as stereolithography, selective laser sintering, etc. also have problems such as high production costs, large deformation of parts, and single composition of ceramic parts.

Abstract

The rapid preparation method for ceramic part comprises: generating three-dimension solid model of the require part on computer by moulding software; layering the model with layered software to obtain shapes of every layer and describe layer contour, taking grid depict to zones out of the contour according to layer shape; filling fused paraffin to the gap of depicts; overlaying layer by layer; wax-removal sintering, and removing the residue to obtain the ceramic part.

Description

technical field [0001] The invention relates to a preparation method of ceramic parts, in particular to a rapid preparation method of ceramic parts. Background technique [0002] The traditional preparation methods of ceramic parts include pouring forming, isostatic pressing forming, extrusion forming, injection molding, etc. It is generally necessary to make a model first by using these methods to prepare ceramic parts, and the shape of the forming is simple, the forming speed is slow, and it is difficult to realize precision. , rapid and personalized manufacturing. [0003] The use of rapid prototyping technology to produce ceramic devices can greatly shorten the cycle and increase the speed, but there are still some problems in the relatively mature rapid prototyping technology. For example, in the laminated entity manufacturing technology, the ceramic film prepared by casting method is used as raw material to produce ceramic parts, which has low strength and complicated...
