Abstract

The invention discloses a scanning method for a material increase manufacturing three-dimensional body. The scanning method includes the steps that a certain value is set to serve as a three-dimensional body surface layer zone threshold value; then the whole three-dimensional body is divided into a surface layer zone and an internal zone according to the threshold value; small light spot heat source scanning is adopted on the surface layer zone, and large light spot heat source scanning is adopted on the internal zone; and scanning is completed. By means of the scanning method, a user can freely set the surface layer zone thickness threshold value according to the machining requirement, a single-deck section to-be-scanned zone of the three-dimensional body is divided into the surface layer zone and the internal zone, different scanning parameters are further adopted to conduct zone dividing scanning on the surface layer zone and the internal zone, the machining accuracy of the three-dimensional body is guaranteed, and the scanning machining efficiency of the three-dimensional body is improved. The user can further take a scanning strategy that scanning machining of the internal zone is carried out one time after the multi-layer surface layer zone is scanned according to the machining requirement, and the machining accuracy and the machining efficiency are balanced to the maximum degree.

Description

technical field

[0001] The invention belongs to the technical field of additive manufacturing, and relates to a scanning method for additively manufacturing a three-dimensional object. Background technique

[0002] In the existing technology, when performing layered scanning processing on a solid three-dimensional object, the same laser parameters are used for scanning and processing the area to be scanned in a single-layer slice of the entire part. However, for most solid three-dimensional objects, the The requirements for processing accuracy are far lower than the requirements for the surface accuracy of parts. Using the existing scanning processing method, a lot of time is consumed in the internal scanning processing of three-dimensional objects, especially for large-scale three-dimensional objects, which seriously affects the scanning of three-dimensional objects. Processing efficiency. Contents of the invention
