A method for producing a nozzle body and a nozzle body. The method includes at least partially processing a nozzle body blank produced by one of an injection molding process or a 3D printing process by laser processing to form the nozzle body. The nozzle body includes a frusto-conical section; at least one nozzle bore having a diameter of less than or equal to 300 μm coupling the frusto-conical section to an outside of the nozzle body; and at least one turbulence channel that is configured to communicate with the frusto-conical section and to taper in a direction toward to the frusto-conical section
