System for forming one or more dimensionally stable objects (1) by selective areawise solidification of a non-dimensionally stable mass (2) comprising a base body (3) which is arranged in particular stationary; a trough (9) connectable or connected to the base body (3) for receiving the mass (2); one or more controllable radiation source (s) (4) for emitting a radiation (5) which is suitable for solidifying the mass (2) and which is designed, in particular, as a light source; a base body (6) on which the object to be formed (1) is buildable or constructed; a holding device (7) for receiving or holding the base body (6); a housing (8) surrounding at least the trough (9) and preferably also the radiation source (4); a movement device (10) which is connected or coupled to the base body (3) and to the holding device (7), wherein the movement device (10) comprises a drive (11), so that the holding device (7) is activated by actuation of the drive (11 ) is movable relative to the base body (3).
