3D Printing Contour Scans for Multi-Beam Alignment Uncertainty

The system performs preliminary calibration to determine lateral alignment uncertainty between multiple energy beams before manufacturing. Based on this pre-determined uncertainty, the system calculates and sets the optimal number of contour scans in advance, preventing surface roughness and subsurface defects before they occur during actual manufacturing.

The system uses feedback from the determined lateral alignment uncertainty to dynamically adjust the number of contour scans. The controller modifies manufacturing parameters based on the measured alignment characteristics of specific beam combinations, creating a closed-loop control system that maintains surface quality while using multiple beams for high productivity.

The system changes the parameter of contour scan number dynamically based on lateral alignment uncertainty. Instead of using a fixed high number of scans for all situations, the system calculates the optimal scan number as a function of measured alignment uncertainty, allowing fewer scans when alignment is good and more scans only when necessary, thus reducing overall manufacturing time while maintaining quality.

The system applies partial action by using only the necessary number of contour scans required to compensate for actual alignment uncertainty, rather than always applying excessive scans. This optimized approach applies just enough correction to achieve surface quality targets without the time penalty of over-correcting with too many scans in every case.
