    Abstract: The present invention relates to materials for a multi-stage method for producing one or multiple molded bodies. The materials may be used in a method including constructing one or multiple molded bodies in layers by repeatedly applying particulate material by the 3D printing method; pre-solidifying the molded body; unpacking the pre-solidified molded body and removing unsolidified particulate material, and final solidification of the molded body for achieving a final strength due to the action of thermal energy. The invention also relates to a device which may be used for this method.

    Abstract: The invention relates to a device (13) for constructing a laminar body (5) from a plurality of superimposed layers of free-flowing material, in particular particulate material, an a build platform (6) within a working area (11). The layers are solidified in locally predetermined regions by the actions of binders and are joined together so that at least one molded body (4) is formed by the solidified and joined regions of the layers. The device comprises a discharging device (1) movable back and forth over the working area (11) in at least one discharge direction and having at least one discharge opening (14) from which the free-flowing material can be discharged in individual superimposed layers during the movement of the discharging device (1). According to the invention at least one body (8, 8a) defining the working area (11) in at least one discharge direction of the discharging device (1) and the build platform (6) are adjustable vertically relative to each other in accordance with the specific progress with which the laminar body (5) is being constructed, in such a manner that a surface of the at least one body (8, 8a) facing the discharge opening (14) is aligned flush with a laminar body (5) topmost layer that is yet to be produced or has already been produced, in order to dose the discharge opening (14) of the discharging device (1) and prevent the discharging device from discharging free-flowing material or in order to discharge free-flowing material not used for the laminar construction into a collecting container (7) when the discharge opening (14) is located above the body (8, 8a).

    Abstract: 1. The present invention relates to a device for manufacture of three-dimensional models by means of a 3D printing process, whereby a spreader device is used to deposit particulate material in layers on a build platform and the particulate material flow, which occurs perpendicular to the spreading direction, is transferred into containers that are actively cleaned by sliders or brushes at the spreader device. It exploits the fact that particulate material that is moves dynamically can only bridge small height differences. The arrangement can be implemented in a space-saving manner beneath the spreading plane.
