Three-dimensional (3D) printing method

Abstract

The invention discloses a three-dimensional (3D) printing method. A 3D printer appeared in the middle of 90 years in 20th century. In practice, the 3D printer is a fast molding device by the adoption of technologies of photocuring, paper stacking and the like. An operating principle of the 3D printer is basically same as that of a normal printer. 'Materials for printing' are arranged in the printer. The 'materials for printing' are liquid or powder and the like. After the printer is connected with the computer, the 'materials for printing' are stacked layer by layer through a computer controlling, and at last a blueprint of the computer is changed into a material object. Fast molding technologies in the market are divided into a 3DP technique, an FDM melting lamination molding technique, an SLA three-dimensional planographic printing technique, an SLS precinct laser sintering, a DLP laser molding technique, an ultraviolet (UV) ray molding technique and the like. At present, the 3D printing method is used in a motor industry, a medical treatment die processing industry and the like. A printing coverage is coated on a polymer clay sheet, an image printing is carried out on the coverage by a normal color printer, the printed image is carried out on counterpoint superposition and stretching to form a 3D image.

Description

technical field [0001] The invention relates to a method for 3D stereoscopic printing, in particular to a method for using an ordinary printer to perform 3D stereoscopic printing. technical background [0002] 3D printers appeared in the mid-1990s and are actually rapid prototyping devices using technologies such as light curing and paper lamination. Its working principle is basically the same as that of ordinary printers. The printer is filled with "printing materials" such as liquid or powder. After being connected to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. This printing technology is called 3D printing technology. Rapid prototyping technologies on the market are divided into 3DP technology, FDM fusion lamination molding technology, SLA stereolithography technology, SLS selective laser sintering technology, DLP laser forming technology and UV ul...
