  • Publication number: 20190375153
    Abstract: The invention relates to a method for producing an at least partially coated object, comprising the step of producing the object from a construction material by means of an additive manufacturing method, the construction material comprising a thermoplastic polyurethane material. Following the production of the object, the method comprises the step of at least partially bringing a preparation into contact with the object, the preparation being selected from: an aqueous polyurethane dispersion; an aqueous dispersion of a polymer comprising OH groups, this dispersion also containing a compound comprising NCO groups; an aqueous preparation of a compound containing NCO groups, but not containing any polymers comprising OH groups; or a combination of at least two thereof. The invention also relates to an at least partially coated object that was obtained by a method according to the invention.

  • Publication number: 20190315062
    Abstract: A method for producing an article in which a layer (200) of meltable polymer is selectively melted at least partially. This takes place according to a selected cross section of the article to be formed. The at least partially melted material is added on layer by layer to a carrier (500) or to previous layers bonded to the carrier (500). A system that is suitable for carrying out the method according to the invention has a substrate (100), a control unit (600), an application unit (700) for applying the particles to the substrate (100), an energy exposure unit (700) and a contacting unit (800).
