Transaction method for constructing a three-dimensional object

The present invention relates to a process for producing a three-dimensional object (10). The method (10) includes receiving digital information of the three-dimensional object through a communication line (14), constructing a three-dimensional object on the basis of the digital information received at least a portion (30), the. At least a portion of the three-dimensional object is built by rapid manufacturing, also the three-dimensional object comprises an exterior surface. The method also comprises applying the vapor smoothing (32) at least on part of an outer surface of the three-dimensional object.
