Abstract

The invention provides an extrusion device for 3D printing of chocolate and relates to the technical field of 3D printing. The extrusion device comprises a gear pump provided with a gear inside, a motor connected with the gear pump, a feeding tank communicating with the gear pump and a spray nozzle, wherein a feeding port and a discharging port are formed in the gear pump, the feeding tank is mounted at the feeding port, and the spray nozzle is mounted at the discharge port; and the motor drives the gear to rotate. The motor drives the gear pump to work, and molten chocolate contained in the feeding tank is sucked into the gear pump from the feeding port and then extruded from the spray nozzle along the discharge port. The gear pump is adopted as a power source to drive the raw material todischarge, the discharging mode of screw injection extrusion for similar products in the market is replaced, so that new material pipes are not required to be mounted and dismounted, continuous feeding can be realized, a printer can work continuously, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to 3D printing, in particular to a chocolate 3D printing extrusion device. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually achieved using digital technology material printers. 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 (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and other fields. [0003] FDM (Fused Lamination Molding) printing technology is one of t...
