High-performance ceramic material extrusion device for 3D printing

Abstract

The invention relates to the technical field of 3D printing, and discloses a 3D printing high-performance ceramic material extrusion device which comprises a shell, a mounting plate and a feeding pipe, an extrusion mechanism is arranged in the shell, and a connection sealing mechanism is arranged at the bottom end of the mounting plate; the extrusion mechanism comprises a small motor, a partition box, a double-concave rotating shaft, a connecting rod, a fixing block, a first ejector rod, a piston pipe, a piston pressing pad, a first through pipe, a first one-way valve, a second through pipe, a second one-way valve, an extrusion needle tube and a working chamber, one end of the double-concave rotating shaft is fixedly installed at the output end of the small motor, and the double-concave rotating shaft penetrates through one side of the working chamber; through the combined action of all the mechanisms, the extrusion time can be staggered, continuous and continuous discharging is achieved, discharging is stable, the discharging amount is controllable, stopping is achieved at any time, the mechanism is simple in structure, driving is achieved only through one driving motor, the manufacturing cost is effectively reduced, and the use purpose is achieved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a high-performance ceramic material extrusion device for 3D printing. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing; 3D printing is usually used Digital technology material printer to achieve. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields; When the extrusion speed...
