Abstract
The disclosure provides methods and systems for measuring a base element of a construction cylinder arrangement in machines for the additive manufacture of 3D objects using a high-energy beam, wherein a measurement pattern is produced from laser light that illuminates the base element, and sites of incidence of the laser light are monitored and evaluated with a camera to produce measuring data about the base element, e.g., position information, orientation information, and/or information about the shape of the surface of the base element. The measurement patterns are produced by deflecting measuring laser beams by an optical scanner system towards the base element, and the camera is arranged laterally offset from the deflected laser beams. The new methods and systems enable measuring base elements in a simple and flexible manner, and require only a small amount of space in the processing chamber.
