Abstract

The invention relates to the field of rapid prototyping manufacturing, particularly to a rapid prototyping system of a gradient material structure. The rapid prototyping system comprises a control module, a powder feeding module and a processing module, wherein the powder feeding module comprises a power mixing device and at least two powder feeding devices; the powder components in the powder feeding devices are different; the powder feeding devices are connected with the powder mixing device; the processing module comprises a laser and a deposition processing head; and the control module is used for performing analysis according to the performances and characteristics of the gradient material structure required to be shaped and controllin the operation of the powder feeding module and the processing module according to the analysis result. According to the rapid prototyping system, the materials and the structure components are continuously and transitionally regulated, the problem that in a dissimilar material connection structure, the structural performance mutates due to the material interface factor is solved, the manufacturing of a compositional gradient structure is easy to implement, the requirement of the utilization performance of an integral structure is better met, the powder utilization rate is high, the prototyping speed is high, and the device is simple in structure.

Description

technical field [0001] The invention relates to the field of rapid prototyping manufacturing, in particular to a rapid prototyping system and method for a gradient material structure. Background technique [0002] Additive manufacturing technology is also known as 3D printing or rapid prototyping. 3D printing is a relatively popular processing and manufacturing technology in recent years. It has a faster processing speed and can process various parts with complex shapes. However, the current metal 3D printing is still limited to the printing of a single material structure, and the 3D printing method of mixing different materials in the same structure to print a 3D printing method with gradient performance characteristics will be an innovative processing technology with great development potential. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, or fuses, to construct objects by stacking and accumulating layer by l...
