Method for calibrating at least one scanning system of an SLS facility or SLM facility

摘要

A scanning system for a laser sintering facility or a laser melting facility is provided so that it can be performed in a short time, can be performed automatically, and can be performed before a structural process. Form a method to calibrate. A method for calibrating a scanning system (6a / 6b) of an installation (1), wherein a line pattern (8a / 8b) is generated in a structure field (2) by a scanning system (6a / 6b), the line pattern being on a planar element. The image is projected and the image is detected by the camera 9 and read into the memory 7, and the difference between the line pattern and the target line pattern is detected by the camera 9 and read into the memory 7. The above steps and the distortion of the line pattern 8a / 8b The step of performing field correction of the linear pattern by the calculation of correction data including information necessary for the correction, and the step of correcting the line pattern thereafter are performed.
