Z-AXIS MEASUREMENT AND CONTROL IN 3D PRINTING OF METAL
Last updated:
Abstract:
Disclosed is the measurement and control of height in the Z-axis of layers produced in an additive manufacturing process. The height of layers being deposited can be monitored, which may involve the use of a fiducial tower to measure a global errors or optical or other means to measure layers on a layer-by-layer basis. Droplet size, pitch and other conditions may be modified to ameliorate or correct detected errors.
