Abstract

The invention relates to a method for 3D printing wood orientation structures based on nuclear magnetic resonance, and the invention belongs to the technical field of 3D printing. In this method, the wood sample is placed in a nuclear magnetic resonance analyzer for scanning. The sample is placed in the horizontal direction and rotated 360° clockwise. Every time a certain angle is rotated, the instrument takes pictures. The 3D model is reconstructed through a series of ordered photos, and the spatial structure parameter information and cell tissue distribution of the wood sample are analyzed. Analyze the obtained three-dimensional model of the wood sample, combine the combined connection form of the three-dimensional building module to rearrange and orient the three-dimensional model of the wood sample, and print the artificial wood through the 3D printer. At the same time, printing materials can also be selected and structured to have different functional properties. Finally, 3D printing is carried out according to different situations to test its mechanical properties, so as to obtain the optimal solution with the best performance.

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...
