A device and a process for producing three-dimensional objects is disclosed. The device has a container (1) for a medium (2) and a three-dimensionally positionable dispenser (4) for release of a material (3), the addition of which to the medium (2) leads to the formation of solid structures, into the medium (2). Addition of the material (3) by moving the dispenser in XYZ direction on a platform (8) below the filling height of the first material (2) in the container (1) leads to the formation of three-dimensional objects.
