Abstract
A coating device arrangement 1 for a 3D printer is disclosed, comprising a coating device 3 having a container 17 defining an inner cavity for receiving particulate construction material which leads to an opening for outputting the particulate construction material, and a stroking member 15a, by which a stroking surface is formed which is directed downward, and which is configured to stroke over construction material output from the opening using the stroking surface to thereby level and/or compress the output particulate material.
