A composite ceramic 3D printer

Abstract

The invention provides a composite material ceramic 3D printer and relates to 3D printing equipment. According to the composite material ceramic 3D printer, the problem that materials are simplex in the prior art is solved. The composite material ceramic 3D printer comprises a discharging nozzle, the discharging nozzle comprises conical sleeves which are sequentially connected in a nested mode stage by stage, and an opening of the bottom end of the conical sleeve of the outmost layer is provided with a sealing end face. The openings of the bottom ends of the conical sleeves are provided with flanges facing inner cavities of the conical sleeves, the diameters of the inner sides of the flanges are equivalent to those of the outer edges of the openings of the bottom ends of the conical sleeves nested in the conical sleeves where the flanges are located, and the inner sides of the flanges are provided with guiding oblique faces of the conical sleeves nested in the conical sleeves where theflanges are located. The sealing end face communicates with a feeding pipe. Through the deformable discharging nozzle structure, composite printing of different materials can be achieved, or the different materials are conveniently switched for printing, the structure is simple, operation is convenient, the cost is low, and the efficiency can be greatly improved.

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

However, the difficulty of forming ceramics limits its use, especially the formation of complex ceramic parts is achieved by means of complex molds.

Complex molds require high processing costs and a long development cycle. Moreover, after the mold is processed, it cannot be modified. This situation is increasingly unsuitable for product improvement or replacement.
