Patent ID: 11267192

Abstract:
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.
