The device has an energy source emitting a beam (9) for consolidating the structural material and a scanner (8) selectively adjusts the beam on different positions in a construction plane. A deflection mirror deflects the beam coming from the energy source to the scanner. The beam travels from the energy source to the scanner in a chamber closed towards outside and an adjusting mechanism (8b,16) is provided for the adjustment of the deflection mirror, which is adjustable from outside of the closed chamber. An independent claim is also included for a method for adjusting a radiation path in a device for making three dimensional object by layer-wise consolidation of structural material on corresponding position on object in each layer.
