are mounted above the bed and record the temper- ature regardless of how far away the powder bed is. The sensors measure with high reliability even at high ambient temperatures in the installation space.


PRINT-HEAD CALIBRATION IN Z-AXIS To obtain repeatable print results, the Z-axis position of print heads is calibrated fully automatically. For this purpose, the print head moves to a defined position and lowers in the Z-axis direction. An inductive LVDT gauge records the Z-axis movement with high accuracy. The determined distance data is taught-in for regular calibra- tion of the Z-axis position of the print head.


PRINT HEAD POSITIONING AND FOCAL POINT CONTROL


With printing processes, the exact height of the print head is a crucial factor for the quality of the final

product. High-speed distance measurement against different material surfaces and reliable edge detection enable a fast readjustment process.


ROBOT PATH CALCULATION IN REPAIR WELDING PROCESSES


In order to calculate the robot path, scanCONTROL laser scanners determine the areas that need to be welded. Providing a high profile resolution and profile frequency, these laser scanners enable quick repairs.


HIGH-PRECISION 3D MEASUREMENT IN FINAL INSPECTION


To check the dimensional accuracy of printed compo- nents, 3D surface scanners are used. These generate high-resolution snapshots of the components in a very short timeframe. The powerful 3DInspect software from Micro-Epsilon evaluates and outputs the point clouds.


3D SCAN PRIOR TO LASER CLADDING / LASER DEPOSITION WELDING Laser profile scanners are used to detect the contour during laser cladding. These scanners detect the exact contour of the object before the weld is deposited. The 3D data is used to exactly determine the guidance of the weld head.


CAD COMPARISON OF THE PRINTED COMPONENT


In order to monitor their production quality, printed components are inspected using Blue Laser scanners. The components are moved past the scanners with a traversing unit. A 3D image is produced from the laser profiles and then compared with the CAD data.
