  A method of applying a material comprising a fusible polymer comprises the step of: applying a filament of the at least partly molten material comprising a fusible polymer from a discharge opening of a discharge element to a first substrate. The fusible polymer has the following properties: a melting point (DSC, differential scanning calorimetry; 2nd heating at heating rate 5° C./min) within a range from ≥35° C. to ≤150° C.; a glass transition temperature (DMA, dynamic-mechanical analysis to DIN EN ISO 6721-1:2011) within a range from ≥−70° C. to ≤110° C.; wherein the filament, during the application process, has an application temperature of ≥100° C. above the melting point of the fusible polymer for ≤20 minutes. There are furthermore blocked NCO groups present in the material comprising the fusible polymer.

  A method for producing an object with layers of different materials in an additive manufacturing process comprises the following steps: •I) providing a construction material heated at least in part to a temperature above its glass transition temperature on a substrate, so that a layer of the construction material is obtained which corresponds to a first selected cross section of the object; •II) providing a construction material heated at least in part to a temperature above its glass transition temperature on a previously provided layer of the construction material, so that another layer of the construction material is obtained which corresponds to another selected cross section of the object and which is connected to the previously provided layer; •III) repeating step II) until the object is formed. In the individual steps II) in the method, the construction material is selected each time from a first construction material and a second construction material different from the first, the first construction material being a polycarbonate, polyester, polyester carbonate, polyimide, polylactic acid, polyvinyl chloride, polystyrene, polymethyl(meth)acrylate or mixtures of at least two thereof. Step II) is carried out at least once with the first construction material and step II) is carried out at least once with the second construction material. The invention further relates to an object that is obtainable using the method described above.
