  • Publication number: 20180186058
    Abstract: The invention relates to a method for producing a three-dimensional object, the outer surface of which comprises at least one surface segment that is created in that a surface segment in two-dimensional form is first produced on a flat base plate by means of an additive manufacturing method (layer-building shaping method), comprising the following steps: I) applying at least one curable polymer or curable reaction resin in flowable form as material webs to a flat base plate by means of a layer-building shaping method in order to create a first layer; II) applying a second layer to the first layer, which second layer is created by means of the same layer-building shaping method as in step I); III) optionally applying 1 to 198 further layers, which are created in accordance with step II), wherein in each case a new layer is applied to the previous layer; IV) curing the layers; V) detaching the cured surface segment from the flat base plate; and VI) shaping the cured surface segment into a three-dimensional obje

  • Publication number: 20180133953
    Abstract: A process for producing an object from a precursor comprises the steps of: depositing a free-radically crosslinked resin atop a carrier to obtain a ply of a construction material joined to the carrier which corresponds to a first selected cross section of the precursor; depositing a free-radically crosslinked resin atop a previously applied ply of the construction material to obtain a further ply of the construction material which corresponds to a further selected cross section of the precursor and which is joined to the previously applied ply; repeating step II) until the precursor is formed; wherein the depositing of a free-radically crosslinked resin at least in step II) is effected by exposure and/or irradiation of a selected region of a free-radically crosslinkable resin corresponding to the respectively selected cross section of the object and wherein the free-radically crosslinkable resin has a viscosity (23° C., DIN EN ISO 2884-1) of ?5 mPas to ?100000 mPas.

  • Publication number: 20180111315
    Abstract: A method of treating at least part of a surface (110) of an article (100) in which an article (100) is treated, at least part of a surface (110, 111) of the article having been produced by an additive manufacturing method from a construction material, and the construction material provides a temperature TG? at which the storage modulus G? of the construction material (determined by dynamic-mechanical analysis according to ISO 6721 at a shear rate of 1/s) is 10 MPa. The article is preferably placed into an evacuable volume and the volume is evacuated. By heating and exerting pressure, the surface is plastically deformed and can be smoothed thereby.

  • Publication number: 20180104922
    Abstract: The invention relates to a method for producing a three-dimensional object, the outer surface of which has at least one surface section that is generated in that, by means of an additive production method (layer-building forming method), initially a surface section is produced on a flat base plate (5) in two-dimensional form, comprising the following steps: I) applying at least one curable polymer or curable reaction resin with a respective elastic modulus according to DIN 53504 (effective: 18 Apr.

  • Patent number: 9868875
    Abstract: A preferably aqueous dispersion comprises carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from ?5:95 to ?75:25. In a process for preparing a dispersion of this kind, carbon nanotubes and graphene platelets are combined so that the ratio by mass of carbon nanotubes to graphene platelets in the dispersion is in a range from ?5:95 to ?75:25. The dispersion can be used as a printing ink for producing electrically conductive films. The invention further provides an electrically conductive film comprising carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from ?5:95 to ?75:25.

  • Patent number: 9231186
    Abstract: The invention relates to an electro-switchable polymer film assembly having a first and a second surface side, comprising at least one pair of electrodes (3, 4) and a polymer matrix (2), wherein structuring particles (5) can be embedded in the polymer matrix and the polymer matrix or the structuring particles consist of an electro-active polymer, wherein furthermore, the first and/or the second surface sides can be transferred from a plane condition into a structured condition by electric switching of the electro-active polymer.
