3D ceramic printing device drying by virtue of heating fan

Abstract

The invention discloses a 3D ceramic printing device drying by virtue of a heating fan. The 3D ceramic printing device drying by virtue of the heating fan comprises a main frame, a printing platform,a ceramic printing device and a heating fan device, wherein the printing platform is capable of lifting along Z axis in the main frame; the ceramic printing device is capable of moving along X axis and Y axis on the upper part of the main frame; the ceramic printing device comprises a printing needle head; and the printing needle head is arranged on an air blowing path of the heating fan device. According to the technical scheme, water in a 3D ceramic printing part is slowly and uniformly removed by virtue of a hot air fluid; influence on the structure of the 3D ceramic printing part is avoided due to no direct touch of the heating fan device with the ceramic printing part; and the heating fan device is high in heating speed, efficiency and heat transfer, sensitive in response to a controldevice, high in controllability, compact in structure, light in weight, and capable of dissipating a part of water of a ceramic paste in a short time to achieve a solidification effect.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing device which utilizes flowing dry hot air generated by a heating fan to remove moisture from ceramic 3D printing parts and accelerate molding. Background technique [0002] Ceramic 3D printing technology is to extrude a ceramic paste with a high moisture content and superimpose it into ceramic parts. Since the ceramic paste with a high moisture content has certain fluidity, if the structure of the printed ceramic part is too high, under the influence of gravity, the underlying ceramic structure is prone to collapse, affecting the overall printing effect. Existing ceramic 3D printers cannot reinforce the newly printed ceramic parts, and a few can only use additional equipment to process points or parts, which causes a large change in the water content of the local structure and uneven shrinkage, resulting in printed ceramic parts. cracking.
