A fast curing device for ceramic 3D printing materials

Abstract

The invention provides a ceramic 3D printing material rapidly-solidifying device and relates to 3D printing equipment. According to the ceramic 3D printing material rapidly-solidifying device, the problem that in the prior art, printing materials are not easily solidified is solved. The ceramic 3D printing material rapidly-solidifying device comprises a discharging nozzle which comprises conical sleeves which are sequentially connected in a nested mode stage by stage. A feeding pipe comprises a main feeding pipe corresponding to an opening of the bottom end of the smallest conical sleeve in the middle and further comprises a first-stage feeding pipe, a second-stage feeding pipe and a third-stage feeding pipe which are arranged corresponding to the edges of openings of the bottom ends of the movable first conical sleeve, second conical sleeve and third conical sleeve correspondingly, and an electromagnet is arranged on the sealing end face. The fourth conical sleeve is fixedly connectedto a mechanism for controlling the discharging nozzle to move, and a semiconductor chilling plate is arranged on the wall of the first conical sleeve. Through the deformable discharging nozzle structure, the temperature of material property of the inner layer and the outer layer of a printed material can be achieved, or meanwhile flowing of an air flow around printed slurry is accelerated to accelerate evaporating solidification of water.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a 3D printer, in particular to a 3D printer mainly made of ceramic materials. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. The essence is to use the integral method to manufacture three-dimensional entities. Layer processing is to divide the three-dimensional model into a series of layers, transmit the information of each layer to the molding machine, and "print" the product layer by layer through liquefied, powdered, and silked solid materials. [0003] Ceramic materials have excellent high-temperature performance, high strength, high hardness, low density, and good chemical stability. They are widely used in aerospace, automotive, and biological industries. The difficult-to-shape feature of ceramics limits its use, especially the molding of complex ceramic parts is achieved by means of complex molds. Complex molds require high p...

Problems solved by technology

[0006] The disadvantage is: if the material is a water-based ceramic suspension, although the material is easy to configure, due to the poor bonding between the materials, the curing and molding speed is slow, and a large amount of material accumulated in a short period of time will crush the green body, especially not suitable for printing Slender cantilever structure, such as the outstretched arm of the character model; if it is an organic-based ceramic slurry, although it has high stability and a long storage period, it needs to increase the low-temperature debinding process, prolong the production period, and increase the manufacturing cost.
