用于3D打印机的涂覆设备组合单元和施加两层粒状构建材料的方法
摘要：
本发明涉及一种3D打印机的涂覆设备组合单元(1)，包括：涂覆设备(3)，涂覆设备(3)具有容器(17)，容器(17)限定了通向用于输出粒状构建材料的开口的用于容纳所述粒状构建材料的内腔；和刮抹构件(15a)，刮抹构件(15a)形成向下定向的刮抹表面并且被配置成刮抹从开口输出的粒状构建材料，以由此抹平和/或压紧输出的粒状材料。所述涂覆设备组合单元(1)还包括设定装置(13)，设定装置(13)被配置成可变地设定刮抹构件(15a)的倾斜角度。
摘要（英）：

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.
