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 present invention relates to articles prepared using a three-dimensional printing method, an auxiliary structure being additionally formed beyond an extension of the one or more components during the construction of components. The invention also relates to an auxiliary structure for components produced by means of three-dimensional printing methods, the auxiliary structure being constructed along with the component and extending beyond a dimension of the one or more components.
