Abstract

Disclosed is a coater assembly 1 for a 3D printer, comprising a coater 3 having a container 5 which defines an inner cavity for receiving particulate construction material which opens into a container opening 7 for outputting the particulate construction material from the container 5, and an output region 9 which defines a coater output opening 11 for outputting the particulate construction material from the coater 3 onto a construction field. The container 5 is movable relative to the coater output opening 11 so that by moving the container 5 relative to the coater output opening a discharge of particulate construction material from the inner cavity through the container opening 7 and the coater output opening 11 onto the construction field is variable.
