The invention relates to a process for the freeform reshaping of semi-finished products and a device therefor, characterized by the fact that a pressure reshaping of the workpiece takes place by means of a pressure device, in particular for stretch-shaping or freeform-shaping of the workpiece, whereby on the other hand, e.g. the rear side of the workpiece is simultaneously heated locally by a laser beam to increase the capacity for changing the shape of the workpiece
