Embodiment

[0010] Example: see figure 1 , a method of correcting the printing accuracy of FDM fusion 3D printers in the XY direction, firstly make a cylinder model on the printing platform of the 3D printer, and then measure the direction of the 45-degree angle with the X-axis guide rail and the direction of the 135-degree angle The diameter of the cylinder model is recorded as D45 and D135 respectively, and the angle between the X-axis guide rail and the Y-axis guide rail is calculated Input the angle α value into the 3D printer control program, and the 3D printer control program calculates and corrects the coordinate points in the printing platform in real time. Relative to the initial coordinate point (X0, Y0) of the printing platform, the coordinate point (x, y) is corrected to (x',y'), where

[0011] The present invention does not need to change the machining process and installation process of the prior art. The method of the present invention is used to correct the printing ac...

Abstract

The invention discloses a method for correcting X-Y direction printing accuracy of an FDM (Fused Deposition Molding) fused 3D printer. The method comprises the following steps: manufacturing a cylindrical model on a printing platform of a 3D printer; then, measuring the diameters of the cylindrical model in a direction which assumes an included angle of 45 degrees with an X-axis guide rail and a direction which assumes an included angle of 135 degrees with the X-axis guide rail; marking the diameters as D45 and D135 respectively; calculating an included angle alpha between the X-axis guide rail and a Y-axis guide rail; inputting the value of the included angle alpha into a 3D printer control program; calculating coordinate points in the printing platform in real time through the 3D printer control program; correcting coordinate points (x, y) in the printing platform into (x', y') relative to initial coordinate points (X0, Y0) of the printing platform, wherein x'=x-(y+Yo)*cosalpha, and y'=(y+Yo) / sinalpha-Yo. By adopting the method, the machining process and mounting process in the prior art do not need to be changed, and the printing accuracy can be increased greatly. The method is an option for a user.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a method for correcting the printing accuracy of an FDM fusion 3D printer in the XY direction. Background technique [0002] The printing process of the Fused Deposition Modeling (FDM) 3D printer is to melt the plastic in a printer head, then eject filamentary material and attach it to the bottom plate to form a thin layer, and then lower the bottom plate to deposit new ones on the basis of the original thin layer. TLC. The printer head moves in the horizontal direction to print out the layers of the 3D product. Therefore, the positioning accuracy of the XY-axis guide rail in the horizontal direction affects the printing accuracy of the product to a large extent. The positioning accuracy of the XY-axis guide rail is not only related to the displacement accuracy of the XY-axis guide rail, but also has a very large relationship with the vertical accuracy of the XY ...
