Problems solved by technology

3D printing is usually achieved by using digital technology material printers. Because 3D printing technology is more complicated, the price of 3D printers is also relatively expensive.
In this way, when printing some models with complex structures and high precision requirements, any small deviation may lead to the scrapping of the entire model, resulting in high production costs

Embodiment Construction

[0020] refer to figure 1 , a kind of three-dimensional printing method of setting reference point that the present invention proposes, the printing nozzle works statically, and the workbench performs three-dimensional movement and can rotate by itself, and the specific working steps are as follows:

[0021] S1. Select a point that is always relatively still with the workbench as a reference point.

[0022] S2. Add reference points to the 3D network model.

[0023] S3. Calculate the three-dimensional distance between each feature point in the three-dimensional network model and the reference point.

[0024] Since the reference point and the workbench remain relatively stationary, printing with reference to the position of the reference point is not only beneficial to control the printing accuracy, but also is not prone to deviation, which is conducive to improving the pass rate of printed objects.

[0025] S4. Slicing and layering the 3D network model to obtain forming inform...

Abstract

The invention brings forward a three-dimensional printing method with the arrangement of a reference point. A print head operates in a static state, and a workbench carries out three-dimensional motion and can rotate. Specific work steps are as follows: selecting a point which always remains motionless relative to the workbench as a reference point; adding the reference point into a three-dimensional network model; computing three-dimensional distance from each feature point in the three-dimensional network model to the reference point; slicing the three-dimensional network model for layering and acquiring molding information at each layer; moving the workbench to adjust relative position between the workbench and the print head, and carrying out layered printing; and acquiring a printing model. The invention brings forward the three-dimensional printing method with the arrangement of a reference point. By the method, printing deviation can effectively be reduced and printing precision and efficiency can be raised.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a three-dimensional printing method for setting reference points. Background technique [0002] Three-dimensional printing, also known as 3D printing (Three Dimensions Printing), belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products, especially some high-value products (such as hip joints or teeth, or aircraft parts) have used this Parts printed by this technology. 3D printing is usually realized by using a digital technology material printer. Since the 3D printing technology is more complicated, the price of the 3D printer is als...
