A method to obtain the performance of metal parts based on 3D printing technology

Abstract

The invention belongs to the field of load-bearing testing of large metal or non-metallic material structural parts, and in particular relates to a method for obtaining the performance of corresponding full-scale metal parts from the performance of reduced-scale non-metallic parts processed and manufactured by 3D printing technology. This method tests the basic physical and mechanical performance parameters of 3D printed non-metallic parts with reduced size, uses the finite element analysis method to calculate its load-bearing state, and deduces the load-bearing state of metal parts with original size. The characteristics and beneficial effects of the present invention: at a lower cost and less time, the non-metallic reduced-size parts processed and manufactured by 3D printing technology can quickly deduce the bearing capacity of the corresponding metal structural parts. Thereby effectively shortening the design and manufacturing cycle of product parts and improving the success rate of design.

Description

technical field [0001] The invention belongs to the field of load-bearing testing of large metal or non-metallic material structural parts, and in particular relates to a method for obtaining the performance of corresponding original-sized metal parts from the properties of reduced-scale non-metallic parts processed and manufactured by 3D printing technology. Background technique [0002] 3D printing, also called rapid prototyping technology, additive manufacturing technology, the principle is to decompose the three-dimensional model designed by the computer into several layers of plane slices, and then the 3D printer superimposes the printing materials layer by layer according to the slice graphics, and finally accumulates into a complete object . Different from the "subtractive manufacturing technology" of traditional manufacturing, 3D printing follows the principle of addition, which can directly convert the design in the computer into a model, and directly manufacture pa...
