1. A method for producing a main body of a nozzle arrangement for applying fluids to a substrate, wherein the main body has at least one first outlet nozzle and at least one second outlet nozzle, and wherein, in the main body, there are formed at least one first fluid channel system and at least one second fluid channel system, via which one or more of the at least one first outlet nozzle or the at least one second outlet nozzle are fluidly connected to one or more of a first connector or a second connector on the main body of the nozzle arrangement, wherein the method is an additive production method comprising:
determining three-dimensional information about the main body, which includes the at least one first outlet nozzle and the at least one second outlet nozzle and in which the at least one first fluid channel system and the at least one second fluid channel system are formed;
converting the three-dimensional information into multiple layers which define cross-sectional layers of the main body, wherein at least one empty space within at least one of the layers is defined which defines the at least one first fluid channel system and the at least one second fluid channel system, the at least one first fluid channel system and the at least one second fluid channel system having a three-dimensionally curved fluid channel section along multiple axes; and
successively forming each of the layers of the main body by melting a metallic powder using one or more of laser energy or electron beam energy.
