Abstract

The invention discloses a scanning path planning method and device based on double lasers and three-dimensional object manufacturing equipment. The method comprises the following steps: at most one to-be-printed workpiece in the current layer section of a working package is scanned by two lasers; other workpieces to be printed in the current layer section of the work package are scanned by only one laser, wherein the to-be-printed workpiece scanned by the two lasers belongs to contours, and the areas filled with the upper surface and the lower surface are scanned by the same laser. According to the scanning path planning method and device based on the double lasers and the three-dimensional object manufacturing equipment, by estimating the scanning time of the current layer section and reasonably allocating the scanning time of each laser, the idle waiting time of the lasers is shortened, that is to say, the scanning waiting time of the lasers is shortened as much as possible on the premise of ensuring the scanning quality.

Description

technical field

[0001] The present application relates to the technical field of additive manufacturing, in particular to a scanning path planning method and device based on dual lasers, and three-dimensional object manufacturing equipment. Background technique

[0002] Additive manufacturing technology is an advanced manufacturing technology with distinctive features such as digital manufacturing, high flexibility and adaptability, direct CAD model drive, fast speed, and rich and diverse material types. tooling mold, so the application range is very wide.

[0003] With the continuous development of additive manufacturing technology, the needs of users are also increasing, so a single laser is increasingly unable to meet all the needs of customers. Multi-laser full-coverage printing equipment, which can improve the production efficiency of additive manufacturing through multiple lasers. Each laser can manufacture each independent part in the sintering area separately, or it...
