Abstract

The invention relates to a method for preparing a heterogeneous function component and a device thereof. The preparation method comprises: 1. a predeterminate metal salt solution which comprises a solution of inorganic salt, an ethanol solution or an acetone solution with a concentration under the saturation as marking ink is prepared, the ink is directly filled in a printer ink boxer; 2. a printing nozzle and a laser head are combined together and the working range thereof are consistent, when working, the laser head coordinately scans the printing ink ejected from the printing nozzle under the control of a computer under the action of the servo system of the laser head and the printing nozzle to achieve the printing ink reacting solidification on the current surface; 3. the printing nozzle ink-jets and prints layer by layer, with that, the laser head matches, scans, reacts and solidifies layer by layer till accomplish, then the heterogeneous function component is prepared. The preparation device is suitable for the preparation method of the invention, and is characterized in that the printing nozzle and laser head are of a combined head structure, the computer control system comprises the laser head and a printing nozzle servo system.

Description

technical field [0001] The present invention relates to rapid prototyping manufacturing technology, specifically a method and device for manufacturing heterogeneous functional components with complex shapes based on the integration of micro-jet accumulation forming and laser scanning sintering forming technology. The main international patent classification number is intended to be Int. Cl. B05B13 / 00 (2006.01) I. Background technique [0002] The development of science and the advancement of technology have put forward higher requirements for the performance of various parts. Usually, parts made of a single (uniform) material cannot meet various almost harsh conditions of use. The Institute of Aeronautics and Astronautics of the Japan Science and Technology Agency proposed the concept of functionally graded materials (Functionally Graded Materials, FGMs) in 1987, that is, the continuous transition of components or structures of multiple materials can simultaneously possess t...
