Problems solved by technology
[0002] With the technological development of additive manufacturing equipment, the size of printed parts is getting bigger and bigger, and the size of the molding is getting bigger and bigger. The defects of traditional n*n matrix multi-galvanometer printing of large-format parts are becoming more and more obvious; and the cost of equipment has increased significantly. Along the direction of the printing wind field, multiple lasers cannot be printed at the same time, resulting in a decrease in printing efficiency, etc.

Embodiment
[0025] see Figure 1~4 , the embodiment of the present invention provides a flight processing and printing control method for additive manufacturing equipment, the printing control method adopts station type printing or mobile printing; The arrangement is n*1 single-row arrangement, the galvanometer system 1 and the scraper powder spreading structure 2 are mechanically connected and move synchronously, the laser of the galvanometer system 1 can just pass through the middle of the scraper powder spreading structure 2 for printing, and the scraper is located in the scraper spreader The side of the powder structure 2 towards the direction of motion.
[0026] The specific control method of the station type printing is as follows:
[0027] Divide the entire printing area into multiple partitions according to the moving direction of the squeegee; import the printing model with the position coordinates of the galvanometer system 1 into the printing control system;
[0028] In each ...

The invention discloses a flight processing printing control method of additive manufacturing equipment. According to the printing control method, station type printing or movable type printing is adopted. The galvanometer system is arranged in an n * 1 single row mode, the galvanometer system and the scraper powder laying structure are mechanically connected and move synchronously, laser of the galvanometer system can exactly penetrate through the middle of the scraper powder laying structure to conduct printing, and the scraper is located on the side, facing the moving direction, of the scraper powder laying structure. The method is suitable for all large-breadth additive manufacturing equipment, meanwhile, the printing breadth is guaranteed under the condition that the number of optical systems is reduced, the printing efficiency of the equipment is improved, and the equipment cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of selective laser melting, and in particular relates to a method for controlling flight processing and printing of additive manufacturing equipment. Background technique [0002] With the technological development of additive manufacturing equipment, the size of printed parts is getting bigger and bigger, and the size of the molding is getting bigger and bigger. The defects of traditional n*n matrix multi-galvanometer printing of large-format parts are becoming more and more obvious; and the cost of equipment has increased significantly. Along the direction of the printing wind field, multiple lasers cannot be printed at the same time, resulting in a decrease in printing efficiency. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a flight processing and printing control method for additive manufacturing equipment, which adopts the method ...
