Abstract

A part (P) includes a first (FP), and a second portion (SP), which meet at an interface (IF). A channel (CH) extends from the first portion (FP) through the interface (IF) into the second portion (SP). Further there is a method to generate the part (P). To refurbish a part with tiny geometry channels, the second portion (SP) is produced by additive manufacturing technology on the interface (IF) with the first portion (FP), the channel (CH) has a first average diameter (DI) in the first portion (FP) and the interface (IF), and the channel (CH) has a second average diameter (D) in the second portion (SP) at said interface (IF). The second diameter (D) is larger than the first diameter (DI). The channel (CH) has a first tapered portion (TP) which narrows in the second portion (SP) at increasing distance from the interface (IF).
