Abstract
A 3D printer is described which is configured to build up a three-dimensional component in layers by forming layers of particulate construction material lying one upon the other and by selectively solidifying a partial region of the respective construction material layer. The 3D printer is configured to build up one or more first three-dimensional components in a first construction space and simultaneously one or more second three-dimensional components in a second construction space which is arranged adjacent to the first construction space. The 3D printer has a coating device arrangement which is displaceable across the first and the second construction space and a printing device which is displaceable across the first and the second construction space.

3D printer (100),
- which is configured to build up a three-dimensional component in layers by forming layers of particulate construction material lying one upon the other and by selectively solidifying a partial region of the respective construction material layer, and
- which is configured to build up one or more first three-dimensional components in a first construction space (B1) which is arranged in the 3D printer, and simultaneously one or more second three-dimensional components in a second construction space (B2) which is arranged adjacent to the first construction space at a horizontal distance therefrom in the 3D printer,
- having a coating device arrangement (30) which is displaceable across the first and the second construction space (B1, B2) in a first horizontal direction (H1), to supply the first and the second construction space with construction material in the form of a respectively uniform construction material layer of the construction material to be solidified, and
- having a common printing device (50) which is displaceable across the first and the second construction space (B1, B2) in a second horizontal direction (H2), to selectively solidify a partial region of a previously applied construction material layer of the respective construction space by a controlled output of a flowable treatment agent,
- wherein the common printing device (50) comprises a common printing head (52) having one or more printing nozzles, which is configured to serve both the first construction space (B1) and the second construction space (B2), and
- wherein the second horizontal direction (H2) is perpendicular to the first horizontal direction (H1).
