A blank for a conduit arrangement includes an annular conduit having a first end and a second end, which is formed by a channel surrounded by a wall. The conduit arrangement has an axis of rotation and the conduit extends in a circumferential direction over an angle of more than 360 degrees about the axis of rotation and forms at least one wind turn. The axis of rotation is arranged perpendicularly to a base surface, the wall having first surfaces which are arranged at a first angle of at least 30 degrees relative to the base surface or in which a surface normal forms at least one second angle of 0 to 60 degrees with respect to the base surface. First partial surfaces of the walls, which face one another in an axial direction, of adjacent turns are arranged spaced apart from one another. The blank is produced by an additive manufacturing process.
