Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0022] The existing 3D printing technology adopts a fixed filling method, which is relatively mechanical; this causes some parts of the 3D printing object model to be easily broken during or after printing due to their insufficient strength. After further analysis, the inventors found that the most easily broken parts appear in the smaller parts of the 3D printing object model. In order to solve this technical problem, the present invention establishes the mapping relationship between the slice graphic area and the filling rate, and performs graphic filling based on the mapping relationship. Therefore, the strength of the smaller parts in the three-dimensional printing object model is enhanced, and the printing quality is improved.

Abstract

The invention discloses a line printing method and device for a three-dimensional line printing machine, wherein according to the method, a mapping relationship between the pattern area and the filling rate is built, wherein the smallest pattern area corresponds to the greatest filling rate. The method also comprises the steps of slicing a three-dimensional line printing object model to obtain slices of each layer of the three-dimensional line printing object model; calculating the pattern area of the slices of each layer; obtaining the pattern area of the current slice, and determining the corresponding filling rate according to the mapping relationship; adopting the current filling rate for carrying out three-dimensional line printing on the current slices. The method and the device adopting the technical scheme have the advantages that the intensity of fine and small parts in the three-dimensional line printing object model can be enhanced, and the line printing quality is improved.

Description

technical field [0001] The invention relates to printing technology, in particular to a printing method and device for a three-dimensional printing machine. Background technique [0002] 3D printing is a form of additive manufacturing technology in which 3D printed objects are created by a 3D printer through successive physical layers. Compared with other additive manufacturing technologies, the three-dimensional printing machine has the advantages of fast speed, low price and high usability. A three-dimensional printing machine is a device that can print out real three-dimensional objects. It is functionally the same as the laser forming technology. It adopts layered processing and superposition forming, that is, the three-dimensional printing object is generated by adding materials layer by layer, which is different from the traditional removal Material processing techniques are completely different. It is called a three-dimensional printing machine because it refers to ...
