Abstract

A nozzle arrangement for applying fluids to a substrate has a main body which is able to be connected to a mounting region of a distributor and which has an end-side side surface. At least one first outlet nozzle for the fluid to be applied to the substrate is provided in or on the end-side side surface of the main body. A first fluid channel system is formed in the main body, via which the at least one first outlet nozzle is connected in terms of flow to a first fluid connector, which is provided in the main body of the nozzle arrangement. The nozzle arrangement is a monolithic component produced by an additive production method.

First claim

What is claimed is:

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.

2. The method according to claim 1 ,
wherein successively forming each of the layers of the main body also comprises melting the metallic powder that includes at least one of cobalt-chromium, HS188, or INCO625.

3. The method of claim 2 ,
wherein successively forming each of the layers of the main body also comprises melting the metallic powder having a particle size between approximately 10 μm and approximately 75 μm.

4. The method of claim 1 , wherein the main body is at least substantially of right-angled form, and wherein an extension region is at least substantially of trapeziform or triangular form and is connected via a longer base side of the extension region to an end side of the main body.

5. The method of claim 1 , wherein an outlet opening of the at least one first outlet nozzle is assigned at least one fluid opening of the second outlet nozzle, the fluid opening having a main flow axis along which the fluid dispensed from the fluid opening of the at least one second outlet nozzle moves, the main flow axis inclined in the direction of the main flow axis of the outlet opening of the first outlet nozzle.
