Zusammenfassung:	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. The coating device arrangement 1 further comprises a setting device 13 which is configured to variably set an inclination angle of the stroking surface 15a. L'invention concerne un système de revêtement 1 pour imprimante 3D, présentant un dispositif de revêtement 3 qui comporte un récipient 17 définissant une cavité interne qui est destinée à recevoir un matériau de construction particulaire et qui débouche dans une ouverture destinée à céder le matériau de construction particulaire, et un élément racle 15a à partir duquel est formée une surface de raclage orientée vers le bas, et qui est conçu pour racler le matériau de construction, déversé par l'ouverture, par ladite surface de raclage aux fins de nivellement et/ou de compactage du matériau particulaire cédé. Le système de revêtement 1 présente également un dispositif de réglage 13 qui est conçu pour le réglage variable d'un angle d'inclinaison de la surface de raclage 15a.
