Embodiment Construction

[0050] See attached Figure 1~5 , in order to obtain the three-dimensional model of complex structural parts, the present invention provides a 3D printing single-point laser scanning path planning method, using the least squares conformal mapping, stretching the three-dimensional curved surface on the two-dimensional plane, and calculating the two-dimensional space The obtained equidistant paths are transformed into equidistant paths in three-dimensional space. In this way, the direction and coverage of the laser beam are controlled, the noise in the overlapping area between adjacent scanning paths is reduced, the scanning time is reduced, and the scanning efficiency and precision are improved. The specific steps are as follows:

[0051] Step 1, scan the initial position and direction definition.

[0052] See attached figure 1 , in a single-point laser scanner, the sensor trajectory is defined as an ordered set of scanner configurations, that is, a set of position and orien...

Abstract

The invention discloses a 3D printing single-point laser scanning path planning method which comprises the following steps: stretching a three-dimensional curved surface on a two-dimensional plane byadopting least square conformal mapping, and converting an equidistant path calculated in a two-dimensional space into an equidistant path in a three-dimensional space; the method comprises five stepsof (1) scanning initial position and direction definition, (2) establishment of mapping between a three-dimensional space and a two-dimensional parameter space, (3) generation of a driving point of ascanning path, (4) determination of a guide vector, and (5) determination of a laser beam axis guide vector, thereby completing scanning path planning and control and obtaining a three-dimensional model of a part with a complex structure. Compared with the prior art, by controlling the direction and coverage rate of the laser beams, the noise of the overlapping area between the adjacent scanningpaths is reduced, the scanning time is shortened, and the scanning efficiency and precision are improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing laser scanning path planning method. Background technique [0002] In recent years, 3D printing technology has been widely used in rapid prototyping of various complex structural parts. In order to realize the 3D printing of complex structural parts, it is first necessary to carry out 3D modeling. Traditional modeling uses computer simulation drawing, which takes a long time and is inefficient, and the accuracy is closely related to the proficiency and accuracy of the modeler. At present, in 3D printing, three-dimensional scanning technology is mostly used for three-dimensional modeling of complex structural parts, and its three-dimensional scanning solutions mainly include photo-based and laser-based. Among them, the camera type has low precision due to its own optical imaging principle. The laser type is divided into multi-head laser type and si...
