Method for 3D printing of wood directional structure based on magnetic resonance imaging

Abstract

The invention relates to a method for 3D printing of wood directional structure based on magnetic resonance imaging and belongs to the technical field of 3D printing. By means of the method, a wood sample is placed in a magnetic resonance imaging analyzer to be scanned, the sample is placed in the horizontal direction and rotates by 360 degrees clockwise, and each time the sample rotates by a certain angle, an instrument takes pictures. Three-dimensional model reconstruction is conducted by photographing a serious of ordered pictures, analysis is conducted, and space structure parameter information and cell tissue distribution conditions of the wood sample are obtained. A wood sample three-dimensional model is obtained through analysis, rearrangement orientation is conducted on the three-dimensional model of the wood sample with the combination of a combined connecting manner of three-dimensional building die blocks, and manmade wood is printed through a 3D printing machine. Meanwhile,selection and structure setting of printing materials can also be conducted so that the wood can have different functional properties. Finally, 3D printing is conducted according to different conditions so that the mechanical performance of the wood can be tested, and an optimal scheme with best performance is obtained.

Description

technical field [0001] The invention relates to the technical field of 3D printing artificial wood, in particular to a method for 3D printing wood orientation structures based on nuclear magnetic resonance. Background technique [0002] Wood is an important natural renewable resource. It is widely used for its high strength-to-weight ratio, good acoustic properties, mild visual effect, and easy processing. It can be seen everywhere from furniture to architecture, from utensils to bedding, and People's lives are closely related. With the gradual increase of people's love for solid wood furniture, my country's wood resources have been weakening year by year, which has accelerated the consumption of wood resources, resulting in a serious shortage of wood supply in our country. In recent years, a large number of artificial fast-growing tree species have been widely planted to meet the global timber supply. The area of ​​planted forests is increasing year by year, and now it ha...
