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.

Abstract: The present invention relates to a method and a device for producing three-dimensional objects based on computer-provided data. Material is extruded on a surface of a workpiece (e.g., in two-dimensions). The workpiece is then moved incrementally so that additional material can be extruded on the new surface of the work piece. These steps are repeated until the 3-dimensional object is completed. The present invention also relates to a device including an extruder system for extruding a build material in multiple directions on a surface of a workpiece, and a conveying component for moving the workpiece incrementally for extruding additional material on the new surface. The method and device preferably allows for the continuous construction of three-dimensional objects.

Abstract: The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform. In so doing, the device provides a material feeding device having a particle material container to supply particulate material in batches from the storage area to the dosing apparatus and to do so with the least possible amount of shearing forces and without significant interaction with the atmosphere.

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.
