Abstract: The invention relates to a device for constructing a laminar body from a plurality of superimposed layers of free-flowing material, in particular particulate material, and a build platform within a working area. The layers are solidified in locally predetermined regions by the action of binders and are joined together so that at least one moulded body is formed by the solidified and joined regions of the layers. The device comprises a discharging device movable back and forth over the working area in at least one discharge direction and having at least one discharge opening from which the free-flowing material can be discharged in individual superimposed layers during the movement of the discharging device.

Abstract: The invention relates to methods and devices for constructing models in layers. A region for constructing models, preferably a construction platform, and a material applying device for applying material onto the region are provided. The material applying device is arranged in a movable manner over the region. The material applying device is designed as a portal such that the material applying device can be moved over the region at least via two linear guides arranged at opposite sides of the region, and the material applying device is arranged around the region such that a portal is formed by at least two portions that extend laterally with respect to the region.
