Description
Technical Field
The invention relates to the technical field of 3D printing, in particular to a polar coordinate 3D printer.
Background
Most of the existing 3D printers using FDM process (except Delta-Delta structure) are based on the mathematical principle of cartesian coordinate system, and the print nozzle module (i.e. hot end) is driven by stepping motor to move on the x-axis and y-axis plane, so as to form the print path. However, the printing process method based on the cartesian coordinate system has a significant disadvantage in printing a circular or curved path, because the x-axis and the y-axis need to move simultaneously, and the circular or curved path is completed by interpolation in the x-direction and the y-direction, the printing speed is slow, and the arc surface is not smooth enough when printing a revolving body, thereby resulting in poor printing precision.
In the current market, a Delta-Delta 3D printer designed based on a polar coordinate system adopts 3 vertical tracks and a lead screw to control the motion of each shaft, and each shaft can move in the tracks (or on the lead screw) along the vertical direction, so that the motion track of a printing nozzle module (namely a hot end) is actually the result of the combined motion of the 3 shafts. Although the problem of poor precision when printing the revolving body is solved in the actual printing, the printing speed is still slow due to the fact that 3 stepping motors are adopted to comprehensively control the motion trail.
