Composite material prepared by laser printing

Abstract

The invention relates to a technology for preparing a composite material by laser printing. A laser printing technology and a composite material preparation technology are combined to prepare the composite material which is low in cost, flexible in application, high in adaptability, stable in performance and reliable in product quality. The technology has the main characteristics that a functional or enhanced phase with higher capacity of absorbing a laser beam with a specific wavelength is buried into a substrate material with relatively lower capacity of absorbing a laser beam with the same wavelength; the laser beam with the specific wavelength is used for scanning the functional or enhanced phase through the substrate material; the functional or enhanced phase absorbs light energy of the laser and converts the light energy into heat energy, so that temperature is increased; the substrate material which is in contact with the functional or enhanced phase is heated to be melted, and the functional or enhanced phase is dipped; the laser beam continues to perform scanning according to a 3D (three-dimensional) printing method so as to obtain the required composite material.

Description

technical field [0001] The invention relates to a technology for preparing composite materials by laser printing. The preparation technology of this composite material involves laser printing molding technology and composite material preparation technology. technical background [0002] As a typical method of modern advanced manufacturing technology, laser technology has been widely used in many high-tech fields. Among them, the technology of preparing various materials and their parts by laser 3D printing has been widely disclosed. The basic principle is that the laser beam near the focus The energy density is high enough to melt a variety of powder materials. Using the digital console to drag the laser head to control the position of the laser beam focus, the molten materials can be accumulated into three-dimensional parts. [0003] Composite materials consist of two or more physically distinct materials that may be separated by mechanical means. Generally, one of the...
