Zusammenfassung:	A test specimen for validating operating parameters of a method for the additive manufacturing of a part by laser melting on powder beds includes at least one upper face, at least one lower face and side faces, including a front side face and a rear side face that are substantially on opposite sides from one another. The test specimen has at least one recess opening onto the front and rear side faces, the recess having a substantially triangular cross sectional shape being delimited by three internal faces, including a first lower internal face oriented upwards, a second upper internal face oriented downwards, and a third upper internal face which defines a narrow wall with one other of the side faces, which is inclined.
