Method and system for preparing part through additive manufacturing, equipment and storage medium

Abstract

The invention discloses a method and system for preparing a part through additive manufacturing, equipment and a storage medium. A physical model of the material performance of the to-be-prepared part is established, the model is subjected to regional infinitesimal processing, the material composition of each region is determined according to the performance requirement of each region, and any adjacent region is a continuously changing component gradient; a three-dimensional model of the to-be-prepared part is established, the physical model is combined with the three-dimensional model, and hierarchical slicing treatment is performed on the three-dimensional model to obtain material component information of each layer of slice and a slice contour track; and the powder composition proportion is obtained through the slice material composition information, the scanning path of a laser printing system is obtained through the slice contour track, additive manufacturing is performed layer by layer according to the powder composition proportion and the scanning path, and the part is obtained through preparation. The process is simple, and material structures with complex shapes can be manufactured.

Description

technical field [0001] The invention belongs to the field of additive manufacturing, and relates to a method, system, equipment and storage medium for preparing parts by additive manufacturing. Background technique [0002] Additive manufacturing technology, also known as 3D printing, is a kind of opposite to the traditional material removal processing method. Based on the three-dimensional digital model, the product is modeled and layered, and the material is usually combined to form a product in a layer-by-layer manufacturing method. craft. Laser cladding (LMD) technology is a new surface modification technology that emerged after the 1980s. Laser melting deposition technology uses a laser beam as a high-temperature heat source to melt a small amount of the surface of the substrate to form a molten pool, and simultaneously sends the metal powder into the laser molten pool through the powder feeding equipment to melt it, forming a metallurgical bond with the base metal and...

Problems solved by technology

Its manufacturing process is extremely complicated. Traditional smart material manufacturing methods can only manufacture smart materials with simple shapes, and it is difficult to manufacture material structures with complex shapes. Moreover, its traditional preparation methods severely limit the development and application of smart material structures.
