Print file generation method and device, computer equipment and storage medium

Abstract

The invention relates to a printing file generation method and device, computer equipment and a storage medium, and the method comprises the steps: carrying out the slicing of a to-be-printed model, obtaining the contour of each layer of slice, determining a target point on the contour of each layer of slice, dividing the contour of each layer of slice into a plurality of sections of curves, for each section of curve, selecting points from target points on the current curve, adding the points into a first queue or a second queue, generating gcode instructions of the points according to the points of the first queue, generating gcode instructions of a Bezier curve according to the points of the second queue, and synthesizing the gcode instructions to obtain a gcode instruction set of the current curve; and combining the gcode instructions of all the curves into the generated printing file, when the target points are not added into the queue, reducing the number of the gcode instructions, wherein when the target points are added into the second queue, the points in the second queue are the gcode instructions for generating the Bezier curve, and reducing the number of the gcode instructions. A printer can directly execute the Bezier curve, the gcode instruction processing efficiency of the printer is improved, and the probability of jamming during printing can be reduced.

Description

technical field [0001] The present application relates to the technical field of 3D printing, in particular to a printing file generation method, device, computer equipment and storage medium. Background technique [0002] Fused Deposition Modeling (Fused Deposition Modeling, FDM) is an important branch of three-dimensional (three-dimensional, 3D) printing technology. In FDM printing, the printer prints according to the gcode command in the print file. The gcode command is generated according to the points on the outline of each layer of the model. In order to ensure the fineness and accuracy of the outline, the points on the outline are very dense, and each One point corresponds to one gcode instruction. The number of gcode instructions is relatively large, but the number of gcode instructions processed by the printer is limited each time. When the processed gcode instruction is executed, the next gcode instruction has not been processed yet. There will be a pause in the p...

Problems solved by technology

In FDM printing, the printer prints according to the gcode instruction in the print file. The gcode instruction is generated according to the points on the outline of each layer of the model. In order to ensure the fineness and accuracy of the outline, the points on the outline are very dense, and each One point corresponds to one gcode instruction. The number of gcode instructions is relatively large, but the number of gcode instructions processed by the printer is limited each time. When the processed gcode instruction is executed, the next gcode instruction has not been processed yet. There will be a pause in the printing, and the printing will not continue until the next gcode command is processed, resulting in some stuck spots on the surface of the printed model
