Abstract
The present invention provides a ceramic body 3D printing molding equipment, comprising: a support platform, a vacuum chamber is formed inside the support platform; a printing platform, the printing platform is arranged in the vacuum chamber, and the printing platform The external force moves along the Z-axis direction; the feeding mechanism, the nozzle of the feeding mechanism is arranged inside the vacuum chamber and correspondingly arranged with the printing platform, and the feeding mechanism is placed on the plane of the XY axis under the external force Internal movement, used to print raw materials layer by layer on the printing platform; pressurization mechanism, the pressurization mechanism is set in the vacuum chamber, used to pressurize the current layer while printing; the first drive mechanism, the first driving mechanism is connected to the supporting platform, and the first driving mechanism is used to provide driving force to the feeding mechanism and the printing platform. The invention can effectively improve the degree of fusion between printed material layers and improve the self-strength of printed products.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing molding device for a ceramic body. Background technique [0002] 3D printing belongs to a kind of rapid prototyping technology. It is based on a digital model file, using powdered metal or plastic and other bondable materials to construct objects by stacking and accumulating layer by layer. ". [0003] Fused deposition modeling is a process of 3D printing. Its principle is: the nozzle is controlled by the computer for X-Y linkage and Z-direction movement. The filament is heated in the nozzle to a temperature slightly higher than its melting point. The nozzle squeezes out. The temperature of the hot melt material is always slightly above the solidification temperature, and the temperature of the molded part is slightly lower than the solidification temperature. As the hot melt material exits the nozzle, it fuses with the previous layer. After the deposition o...
