Abstract
On an additive manufacturing 3D printer, parts are constructed by forming thin layers of pulverized material and selectively melting or binding it. To have a good part quality it is important to control the distance between the print heads and the powder bed surface. It can be achieved by calibrating the height of the roller with respect the print head carriage with a proper mechanism. In this article, a mechanism is described to precisely calibrate the height of the roller by means of a differential screw combined with a lever to ensure adjustment is fine enough.
