[0039] The second embodiment of the present invention provides a printing method of the above-mentioned 3D printer: obtain the 3D model of the printing workpiece through self-built model or 3D scanning. Import the 3D model of the printed workpiece into slicing software to perform slicing operations, and transmit the generated code to the above-mentioned 3D printer. The heated liquid is injected into the high-temperature printing container, so that the bottom surface of the printing platform is immersed in the high-temperature liquid in the high-temperature printing container, and the top surface of the printing platform exposes the liquid surface of the high-temperature liquid. The moving platform drives the print head to perform single-layer printing on the printing platform to obtain the first layer of printed pattern layer, and to perform single-layer printing on the top of the obtained first layer of printed pattern layer to obtain the second layer of printed pattern layer ...

Abstract

The invention provides a 3D printer. The 3D printer comprises a motion platform, a printing head, a printing platform and a high-temperature printing container, wherein the motion platform is arranged above the high-temperature container; the upper end of the printing head is connected onto the motion platform; the lower end of the printing head extends into the high-temperature printing container; the high-temperature printing container is filled with high-temperature liquid; the lower end of the printing head is positioned above a liquid surface of the high-temperature liquid; and the motion platform is used for driving the printing head to move according to preset printing track in the high-temperature printing container. According to the 3D printer provided by the invention, specific heat capacity and density of liquid are greater than those of air, and temperature uniformity of liquid is easily controlled, so that the motion platform and other electronic elements inside a housing can be prevented from being affected by the high temperature. The invention further provides a printing method for the 3D printer. Contact between a printed workpiece and oxygen gas is reduced, holes and unevenness are avoided, and quality of the printed workpiece is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printer and a printing method thereof. Background technique [0002] 3D printer is a kind of rapid prototyping machine. It is based on digital model files, using special wax, powdered metal or plastic and other bondable materials to manufacture three-dimensional objects by printing layers of bonding materials. [0003] Conventional 3D printers generally use air heating to set up a closed chamber and additional heating devices to obtain a high-temperature printing chamber that is higher than the ambient temperature. The high-temperature printing chamber is sensitive to the installation position of the temperature sensor, and different installation positions may lead to different measurements. The results and the corresponding control strategy, and due to the small specific heat and low density of the air, it is difficult to control the uniformity of the temper...
