Problems solved by technology

Therefore, when processing thin-walled parts with a circular cross-section (the radius of the inner and outer circles is not much different), the use of XY Cartesian coordinates cannot fundamentally solve this problem
[0004] The workbench of the existing polar coordinate 3D printer is changed to a rotating workbench, but it can only print a rotating body centered on the center of the workbench, or products with a center hole. There are few types of printed products and the size range of printed products is limited. and the printing speed is slow

Abstract

The invention provides a 3D printer based on polar coordinates. The 3D printer comprises a bottom plate, a workbench arranged on the bottom plate and capable of moving in a plane according to the polar coordinates, and a printing head having an adjustable distance with the workbench. The 3D printer provided by the invention realizes the completion of printing of the printing head for any curve and straight line in a working stroke under a coordinate system through the workbench, and has the advantages that the printing speed is fast, the curved surface dimensional accuracy of the printed parts is high, and the surface quality is also greatly improved; and meanwhile, the 3D printer provided by the invention is simple in structure, small in size and large in working range, the movement amounts of the printing head and the workbench during curved surface printing are much smaller than those under a rectangular coordinate system, the noise is also greatly reduced, and the service life is longer.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional additive manufacturing, and relates to three-dimensional rapid prototyping equipment, in particular to a polar coordinate 3D printer. Background technique [0002] At present, the 3D printers developed in the domestic and foreign markets are all three-dimensional rapid prototyping in the Cartesian coordinate system. The principle is to complete the manufacturing technology of the physical prototype layer by layer based on the CAD model (electronic model). Specifically, the rapid prototyping technology is to discretize the three-dimensional solid model established on the CAD system, divide the height of the solid model into several thin layers, and use the layer information of these different heights to control the forming equipment for layer processing. Layers are stacked to obtain the three-dimensional shape required for processing. [0003] Analysis of 3D printer based on Cartesian co...
