Problems solved by technology

However, changing the printing layer height will affect the printing quality. At the same time, the stability of the printing line width can be better controlled when the printing line width matches the printing nozzle diameter. If the printing line width is different from the printing nozzle diameter It will be difficult to control the printing line width stability; and adjusting the printing line width will also reduce the printing quality

Embodiment Construction

[0023] 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.

[0024] The invention does not modify the characteristic parameters of the printing machine, but adopts the method of detection and fine-tuning the model to adapt to printing, and improves the problem of line cracks on the external horizontal surface of the printed part. see figure 1 , is a schematic flowchart of the printing method of the three-dimensional printing machine of the present invention, which includes the following steps:

[0025] Step 101 , slice the 3D printing object model to obtain slices of each layer of the 3D printing object model.

[0026] Using the existing technology to slice the 3D printing object model, the slice thickness can be set by yourself, for example, slice every 0.2mm.

[0027] Step 102, compare the data differenc...

Abstract

The invention discloses a line printing method and system of a three-dimensional line printer, wherein the method comprises the steps of conducting slicing to a three-dimensional line printing object model, and obtaining slices of the three-dimensional line printing object model of each layer; conducting data difference comparison between two adjacent slices, recognizing closed horizontal plane of the top of a wall of each layer of the three-dimensional line printing object model, and recording the closed horizontal planes of each slice; determining the positions of wall thickness needed repairing treatment in the closed horizontal plane, and treating the positions as the positions of the wall thickness to be treated; conducting deformation treatment to the positions of the wall thickness to be treated, reaching the preset wall thickness, and obtaining the repaired slices of each layer of the three-dimensional line printing object model. By means of the method and system, the forming quality of external horizontal planes of a three-dimensional line printing piece can be improved.

Description

technical field [0001] The invention relates to printing technology, in particular to a printing method and system 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 ...
