3D printer

Abstract

The invention relates to a 3D printer. The 3D printer comprises a movable frame arranged on a rack, a working platform, a plurality of sliding seats, a nozzle, an X-direction driving piece, a Y-direction driving piece and a Z-direction driving piece. The movable frame is in sliding connection with the rack, the movable frame is in a regular polygon shape matched with the bottom face of a workpiece, and the movable frame is located above the working platform; the sliding seats are connected with the movable frame in a sliding mode, the multiple sliding seats correspond to the multiple edges of the movable frame respectively, and the sliding direction of each sliding seat is parallel to the edge close to the sliding seat. The nozzle is connected with the sliding seat, and the moving direction of the nozzle is perpendicular to the sliding direction of the sliding seat; the X-direction driving piece is arranged on the movable frame so as to enable the sliding seat to move; the Y-direction driving piece is connected with the nozzle so that the nozzle can move in the direction perpendicular to the moving direction of the sliding seat. The Z-direction driving piece is used for enabling the movable frame to get close to or away from the working platform. The 3D printer has the effect that workpieces in the shapes of regular quadrangular prisms, regular hexagonal prisms and the like can be more efficiently manufactured through the 3D printer.

Description

technical field [0001] The present application relates to the field of printing equipment, in particular to a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. The working principle of 3D printer is basically the same as that of ordinary printer. It is to superimpose printing materials layer by layer through computer control. Finally, the blueprint on the computer is turned into a real object, so this technology is often used in the fields of mold manufacturing, industrial design, etc. to make models or to directly manufacture some products. [0003] In related technologies, a 3D printer includes an XYZ three-axis screw slide table, a nozzle, and a working platform arranged on a frame. The movement in one direction; the working platform is fixed on the frame and is located under the nozzle, and the surface of the working platfo...

Problems solved by technology

[0004] For the above-mentioned related technologies, there is a defect that the production efficiency of this kind of 3D printer is low when the products produced are in the shape of regular square prisms, regular hexagonal prisms, and regular octagonal prisms.
