Method for forming needed article and dot-matrix graphic by utilization of 3D printing platform

Abstract

The invention provides a method for forming a needed article and a dot-matrix graphic by the utilization of a 3D printing platform. The method includes the steps that a 3D model of the article is established, and feature point information data are stored; a 3D model of the dot-matrix graphic is established, and parameters relevant to the dot-matrix graphic are stored; the 3D model of the article and the 3D model of the dot-matrix graphic are combined to form a combined 3D model; according to the combined 3D model, N cross section layers are generated to obtain N corresponding cross section layer data; forming material of the article and forming material of the dot-matrix graphic are injected into the 3D printing platform, and the two kinds of forming material are accumulated layer upon layer to form a finished product according to the N cross section layer data. The dot-matrix graphic and the article can form an integrated structure, the solidifying performance between the dot-matrix graphic and the article is improved, and the dot-matrix graphic is prevented from falling off the surface of the article; through two times of verification, it can be guaranteed that the finished product and the combined 3D model are uniform.

Description

technical field

[0001] The invention relates to a 3D printing method, in particular to a method for forming required items and dot matrix graphics using a 3D printing platform. Background technique

[0002] The dot matrix pattern is one of the anti-counterfeiting marks, and it is formed by arranging multiple ink dots according to a certain algorithm. By identifying the dot matrix pattern, the authenticity of the current item that has a binding relationship with it can be known. Therefore, when the identified dot matrix pattern is true, it is determined that the current item embedded with the dot matrix pattern is true.

[0003] At present, since the dot matrix graphics are implanted in the proper position of the required items through printing equipment, jet printing equipment or printing equipment, the dot matrix graphics are prone to damage during the printing, jet printing or printing process. Thereby, the processing cost is increased.

[0004] In addition, in the Chine...
