Additive manufacturing method for light shielding body with multi-ray shielding and self-generating functions

Abstract

The invention discloses an additive manufacturing method for a light shielding body with multi-ray shielding and self-generating functions. The method comprises the following steps that firstly, three-dimensional interlaced structure modeling is carried out by using three-dimensional modeling software, the structure is further designed and optimized through finite element engineering analysis software, and a printing path of a framework is obtained; secondly, a framework material, multiple nuclear ray shielding materials and a photoelectric material are uniformly dispersed respectively, and a 3D printing special material is prepared; thirdly, a framework of the three-dimensional interwoven structure is printed from the framework material according to the printing path, an outer side filling structure is printed from the plurality of nuclear ray shielding materials outside the framework, and an internal filling structure is printed from the photoelectric material in the framework; and finally, printing is carried out through layer-by-layer stacking until a nuclear radiation shielding light additive sample is processed. According to the method, complex structural design is achieved through the additive manufacturing process, entity machining and manufacturing are achieved, and the defects of traditional manufacturing and machining of the nuclear radiation shielding body are overcome.

Description

technical field [0001] The invention relates to the field of nuclear radiation shielding design, in particular to a lightweight shielding additive manufacturing method with multi-ray shielding and self-generating functions. Background technique [0002] During the fission process of nuclear fuel in the reactor, a large number of escaped neutrons, gamma rays and other rays will be produced. In the design of the shielding protective layer, because of the many types of nuclear radiation and the uncertainty of the movement of microscopic particles, thick and dense shielding materials are often used for simple layer-by-layer superposition and wrapping for shielding. Constrained by the defects of traditional manufacturing technology, each layer of shielding material can only be manufactured separately, so there are problems such as the complex structure of the shielding body is difficult to form, the mechanical properties between layers are poor, the development cycle is long, and...
