Portable 3D printer based on polar coordinates

Abstract

The invention belongs to the technical field of 3D printers, and particularly discloses a portable 3D printer based on polar coordinates. The portable 3D printer comprises a base, a Z-axis movement mechanism, a working platform and a sliding table, the sliding table provides steering operation for the working platform, and the working platform can move in a plane; the Z-axis movement mechanism andthe sliding table are movably connected with the base, and the sliding table only does rectilinear motion; and the working platform and the sliding table are subjected to positioned fixing through abearing, and the working platform only does circling motion. The portable 3D printer based on the polar coordinates is accurate and stable in printing, high in printing quality, high in rate, convenient to detach and easy to carry.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and more specifically relates to a portable 3D printer based on polar coordinates. Background technique [0002] 3D printing is a kind of rapid prototyping technology, which uses adhesive materials for layer-by-layer stacking. In today's domestic and foreign markets, XYZ 3D printers and delta 3D printers are the mainstream in the Cartesian coordinate system. Several points in the Cartesian coordinate system are piled up to obtain the required three-dimensional model. [0003] However, from the perspective of the structure of the rectangular coordinate system, in the rectangular coordinate system, the printing movement must rely on the accurate three-axis linkage of XYZ. This three-axis linkage mechanism is more complicated, takes up a lot of space, and the printing efficiency is low. When the printers under the system want to print parts containing rotating bodies such as rounded corners an...

Problems solved by technology

[0003] However, from the perspective of the structure of the rectangular coordinate system, in the rectangular coordinate system, the printing movement must rely on the accurate three-axis linkage of XYZ. This three-axis linkage mechanism is more complicated, takes up a lot of space, and the printing efficiency is low. When the printers under the system want to print parts containing rotating bodies such as rounded corners and ring walls, they use straight lines to approximate realistic arcs. This printing method has a huge error, and the product cannot meet the high-precision requirements.

[0004] In terms of stability, in order to meet the overall stability, most of the 3D printers on the market are three-dimensional structures made of sheet metal, which are bulky and cannot be disassembled, and the printing area is small

Unable to meet people's requirements for easy portability
