AI Technical Summary

Technical Problem

In multi-laser 3D printing, the complex laser optical path leads to problems such as overlapping or incomplete printing in the splicing area. Existing calibration methods are cumbersome and costly, making it difficult to guarantee the processing accuracy of large parts and reduce material waste.

Method used

By setting laser absorption areas and holes at calibration points, measuring the power of the laser beam using a power meter, adjusting the laser position parameters so that the power passing through the holes reaches or exceeds 90% of the rated power, calibrating the coordinates of multiple lasers one by one, and calibrating the laser position using a laser superposition method.

Benefits of technology

It achieves simple and efficient multi-laser calibration, reduces operating costs, improves splicing accuracy, avoids material waste, and simplifies the operation process.
