Classification: CPC B  G | IPC B

Claim 1:
2. The 3D printing method according to claim 1, wherein Step S3 further comprises:
dividing a single-layer printing area of the geological model into an intact rock mass area, a rock mass structure area, a sensor pre-burying area and a boundary transition area, which printing paths are connected with one another according to the 3D digital model of the intact rock mass and the rock mass structure, and setting different printing parameters for subareas, wherein a layer height of the intact rock mass area and a layer height of the rock mass structure area are in an integer multiple relation;
automatically adjusting a line width of each of the subareas according to geometric dimensions of the printing area, so that the printing area is an integer multiple of the line width in dimension;
enabling the planned printing paths to be automatically generated in parallel with a long axis of the rock mass structure area;
performing a self-adaptive adjusting on the printing parameters of the boundary transition area; and
automatically reserving a sensor pre-burying position in the 3D digital model of the intact rock mass and the rock mass structure in the sensor pre-burying area during the planning of the printing paths;
wherein when the 3D printing reaches the sensor pre-burying position, performing the self-adaptive adjusting on a discharging speed and the traveling speed of the print heads.
