A method for manufacture of at least one component of a field device for determining or monitoring a process variable, wherein the field device is applied in automation technology and is manufactured from at least one material. The method comprises method steps as follows: specifying at least one structure related and/or material related boundary condition of the component and/or a boundary condition relevant for the functionality of the component and/or at least one external boundary condition, which takes into consideration the influence of environmental conditions on the component at the location of use; optimizing the structure of the component via a finite element model taking into consideration the at least one structure related and/or material related boundary condition and/or the at least one boundary condition relevant for the functionality of the component and/or the at least one environmental condition, wherein the optimized structure of the component is described by digital data; transferring the digital data, which describe the optimized structure of the component, to a 3-D printer; and printing the component in accordance with the digital data.
