Abstract

The invention belongs to the technical field of 3D printing and particularly relates to a high-temperature 3D printing machine based on polar coordinate motion. The high-temperature 3D printing machine comprises an inner cavity and an outer shell arranged on the outer portion of the inner cavity in a sleeving mode. The inner cavity is located in the middle of the outer shell and comprises a metal supporting outer shell body, an insulation layer and a multistage heating device which are used for achieving step temperature rising and maintaining. A nozzle moving motor and a support are arranged between the top of the inner cavity and the top of the outer shell. A hole is formed in the top of the inner cavity. The linear motion nozzle is connected with the nozzle motor through the support and extends into the inner cavity through the hole. The nozzle moving motor drives the linear motion nozzle to do linear motion. A rotary composite molding platform is arranged in the inner cavity. Materials sprayed out by the nozzle are molded on the rotary composite molding platform. Through the printing machine, the temperature of a molding space can be kept constant, the printing motion path of the printing machine is improved, and the molding problems of molding buckling, layering and the like of high-temperature printing of existing FDM printing machines can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and especially designs a high-temperature 3D printer based on polar coordinate motion, which can effectively solve molding problems such as warping and delamination in high-temperature printing. Background technique [0002] 3D printing technology, also known as Rapid Prototyping Manufacturing (RPM) or additive manufacturing technology, involves mechanical engineering, material engineering, digital control, reverse manufacturing, CAD technology, and computer technology. The basic principle of 3D printing technology is "printing layer by layer, superimposing layer by layer", that is, the 3D model is first generated by CAD software, and then sliced ​​and sliced ​​by the host computer slicing software (such as cura, Repetier-Host, Retinacreate, etc.) Plan the path, import the generated G-code file to the lower computer controller, and then the controller controls the 3D printing device to reprod...
