A method for manufacturing a component of a hearing device (2, 2'), wherein at least one auditory canal of a wearer designated for the hearing device (2, 2') is measured, and measurement data of the auditory canal are generated, wherein a first value for a material property of at least a first delimited region of the component is determined on the basis of the measurement data, wherein a second value, for the material property of a second delimited region of the component is determined on the basis of the measurement data, said second value differing from the first value and said second delimited region being separate from the first delimited region, wherein as a first value and a second value for the material property, a respective a value of a modulus of elasticity is determined, and the first value is determined to be greater than the second value for the modulus of elasticity, wherein the component is manufactured in such a way that for the at least first delimited region of the manufactured component, the material property has the first value, and for the second delimited region of the manufactured component, the material property has the second value, wherein a region is manufactured as a first delimited region of the component which forms a free end to be worn in the auditory canal when wearing the component as specified for its intended use, and wherein a region is manufactured as a second delimited region of the component, which is spaced apart from the eardrum of the wearer by the first delimited region when wearing the component as specified for its intended use, wherein the first delimited region and the second delimited region of the component are manufactured in one piece by means of a 3D printing process, and wherein the first value and the second value of the material property for the first and the second delimited region (6, 8), respectively, is set via a corresponding parameter (P1, P2) of the 3D printing process. wherein a first value for a material property of at least a first delimited region of the component is determined on the basis of the measurement data, wherein a second value, for the material property of a second delimited region of the component is determined on the basis of the measurement data, said second value differing from the first value and said second delimited region being separate from the first delimited region, wherein as a first value and a second value for the material property, a respective a value of a modulus of elasticity is determined, and the first value is determined to be greater than the second value for the modulus of elasticity, wherein the component is manufactured in such a way that for the at least first delimited region of the manufactured component, the material property has the first value, and for the second delimited region of the manufactured component, the material property has the second value, wherein a region is manufactured as a first delimited region of the component which forms a free end to be worn in the auditory canal when wearing the component as specified for its intended use, and wherein a region is manufactured as a second delimited region of the component, which is spaced apart from the eardrum of the wearer by the first delimited region when wearing the component as specified for its intended use, wherein the first delimited region and the second delimited region of the component are manufactured in one piece by means of a 3D printing process, and wherein the first value and the second value of the material property for the first and the second delimited region (6, 8), respectively, is set via a corresponding parameter (P1, P2) of the 3D printing process.
