Abstract (en)

[origin: WO2019223866A1] The invention relates to a blank (1) for a conduit arrangement (2), at least comprising an annular conduit (3) having a first end (4) and a second end (5), which is formed by a channel (7) surrounded by a wall (6). The conduit arrangement (2) has an axis of rotation (8) and the conduit (3) extends in a circumferential direction (9) over an angle of more than 360 degrees about the axis of rotation (8) and forms at least one wind (10) turn. The axis of rotation (8) is arranged perpendicularly to a base surface (11), the wall (6) having first surfaces (12) which are arranged at a first angle (13) of at least 30 degrees relative to the base surface (11) or in which a surface normal (31) forms at least one second angle (32) of 0 to 60 degrees with respect to the base surface (11). First partial surfaces (15) of the walls (6), which face one another in an axial direction (14), of adjacent turns (10) are arranged spaced apart from one another. The blank (1) is produced by an additive manufacturing process.
