Description

[0002] For 3D printing equipment, the printing quality and efficiency of parts are very important. Therefore, the equipment may have multiple laser printing conditions. Under normal circumstances, a single laser prints a single part, and each laser is responsible for printing part of the part, which can ensure the accuracy of the part size and the printing efficiency. However, some parts are large in size, and a part almost covers the entire printing platform. If a single laser is used for printing, the printing time is long, and the cost of a laser is also wasted. At this time, two lasers or even multiple lasers are needed to print the same part, which can save half of the printing time.

[0003] Under normal circumstances, the relative position of the laser is fixed, but as the printing time of the equipment increases, the relative position of the laser printing will deviate, resulting in poor bonding of the parts at the joint printed by the laser splicing. The size, appearance and printing quality of the part will be seriously affected, and even the part will be scrapped. Therefore, the splicing accuracy of the equipment needs to be checked and debugged when printing spliced parts. UTILITY MODEL CONTENT
