The invention relates to a cultural relic building reduced
scale model reproduction method based on an ancient tenon-and-mortise structure and 3D printing, and the method comprises the steps: S1, three-dimensional data collection: scanning a cultural relic building entity through a three-dimensional
scanner, and obtaining three-dimensional
point cloud data; s2, dismantling and parametric modeling:
processing the three-dimensional
point cloud data, dismantling the whole model of the cultural relic building, constructing a standard beam component
library, a standard column component
library, a beam-beam, beam-column and column-column
mortise and tenon joint node
library according to a standard modulus, and constructing a model library of other parts of the cultural relic building; s3, reduced scale proportion 3D printing is conducted, specifically, the three-dimensional models of all the parts in the model library are scaled according to the reduced scale proportion,
slicing processing is conducted, and all the parts of the cultural relic
building model are printed in batches; and S4,
assembly and
verification: carrying out structure
assembly, finally forming an overall reduced
scale model, and finally verifying the structure stability. The device has the advantages of being stable in structure, high in detail reduction degree and high in
manufacturing efficiency.
