Abstract

The invention relates to a method for manufacturing amplified vivid sharkskin squama, which comprises the following steps: 1) pre-treating the sharkskin; 2) precisely scanning the sharkskin squama and three-dimensionally modeling; and 3) three-dimensionally printing the vivid amplified sharkskin squama. By using the method, an amplified model of the vivid sharkskin squama can be acquired by usingthe techniques of high-precise scanning, three-dimensional printing and quick forming. The method is advanced. The vivid sharkskin squama can be directly viewed. In the fluid with high dynamic viscosity, the anti-dragging efficiency of the vivid sharkskin squama can be tested, thereby achieving the anti-dragging efficiency of the vivid sharkskin squama. The method is consistent with the development of the bionic anti-dragging surface manufacturing technique and has wide application prospect and high practical value.

Description

technical field

[0001] The present invention relates to a method for enlarging and manufacturing realistic shark skin scales, more particularly, it refers to a method of using high-precision scanning, software modeling, and three-dimensional printing rapid prototyping technology to manufacture shark skin scales with a high and realistic shape. Similar bionic drag-reducing surfaces. Background technique

[0002] The manufacturing technology of shark-like drag-reducing surface with shark-like scale grooves as the core content is one of the hotspots and difficulties of current research, and the manufacture of realistic shark skin scales is the goal of scholars from all over the world.

[0003] The shark known as the "shark skin effect" has evolved into a non-smooth grooved drag-reducing surface that meets its own survival needs and can reasonably regulate the external fluid medium through continuous self-adaptation, self-learning and self-organization. However, the attempt to ...
