Additive Manufacturing & 3D Printing

In additive manufacturing, different parameters have to be monitored. Particularly where high manufacturing quality is required, sensors from Micro-Epsilon monitor positioning, powder application and component dimensioning tasks. Laser sensors, laser scanners, inductive displacement sensors based on eddy currents and capacitive displacement sensors are just some of the sensors used.

3D scan prior to laser cladding / laser deposition welding

Laser scanners from Micro-Epsilon 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. …
