Thin-wall tubular model slicing method, system and printing method for five-axis 3D printer

Abstract

The invention provides a thin-walled tubular model slicing method, system and printing method of a five-axis 3D printer, including: establishing a coordinate system, reading the three-dimensional model of the workpiece to be printed; extracting the center of gravity of each height cross-section of the three-dimensional model, and sequentially Connect to obtain the center of gravity curve; perform rotation transformation on the working turntable, so that the projection of the curvature vector of the center of gravity curve of the current level of the 3D model on the horizontal plane is zero, obtain the rotation attitude information of the working turntable corresponding to the current level of the 3D model, and calculate the 3D model Slice information of the current height layer; update the current height layer of the three-dimensional model, repeat until the layered slice is completed, and obtain the layered slice information of the workpiece to be printed; the present invention makes the center of gravity of the current height layer of the three-dimensional model by rotating and transforming the turntable table The projection of the curvature vector of the curve on the horizontal plane is zero, which realizes the adjustment of the posture of the 3D model to be vertically upward, realizes unsupported printing, good printing effect, and high surface precision of the molded part.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and particularly relates to a thin-walled tubular model slicing method, system and printing method of a five-axis 3D printer. Background technique [0002] 3D printing, also known as additive manufacturing, was born in the mid-to-late 1980s. It integrates information technology and manufacturing technology and is considered to be one of the important symbols of the third industrial revolution. The advantage of 3D printing technology is that it can be directly generated by computer. The three-dimensional digital model of the 3D model can generate an entity of any shape by stacking materials layer by layer, thus making the production and manufacturing more convenient and more suitable for the future personalized manufacturing mode. Compared with the traditional subtractive manufacturing technology, it greatly reduces the time cost and material loss. At present, 3D printing has more and more ap...
