Abstract

The invention relates to the technical field of additive manufacturing, and particularly discloses a method for planning a laser scanning path of a thin-walled part. The method for planning the laserscanning path of the thin-walled part comprises the following steps that a three-dimensional model of the to-be-formed thin-walled part is established and is divided into a plurality of slice layers;and scanning paths of the slice layers are planned, wherein the number of the scanning paths is more than one, and each scanning path comprises a center line coinciding with the center of the corresponding slice and / or a following line parallel to the contour line of the corresponding slice layer. The invention further provides a 3D printing method adopting the method for planning the laser scanning path of the thin-walled part. By the adoption of technical solution, the thickness of a blank of the thin-walled part can be decreased, and the forming quality of the part is improved.

Description

technical field

[0001] The invention relates to the technical field of additive manufacturing, in particular to a laser scanning path planning method and a 3D printing method for thin-walled parts. Background technique

[0002] Thin-walled parts are increasingly widely used in various industrial sectors because of their light weight, material saving, and compact structure. However, the processing of thin-walled parts is a difficult problem in turning because of poor rigidity and weak strength of thin-walled parts. , It is very easy to deform during processing, which increases the shape and position error of the part, and it is difficult to guarantee the processing quality of the part. Therefore, 3D printing to manufacture thin-walled parts is constantly being promoted. For thin-walled parts, especially large thin-walled parts, when 3D printing is used to manufacture part blanks, due to the small thickness of the parts themselves, it is easy to cause problems such as excessi...
