1. A method for treatment of polymer elements obtained by a powder-based additive manufacturing process, the method comprising:
applying on the element vapor of a treating agent comprising at least one monovalent or polyvalent alcohol while the treating agent is being applied under a pressure of about 0.01 to about 0.9 bar, and thereafter removing the treating agent and optionally recovering at least part of the treating agent, wherein applying on the element the vapor of the treating agent comprises circulating a turbulent flow of the vapor of the treating agent by an impeller or a propeller.
