Zusammenfassung:	The disclosure relates to an apparatus (10) for manufacturing a metallic component (C), and corresponding methods. The apparatus (10) may include a build plate (26) with a build surface (36) and an aperture (38). The apparatus (10) may also include an actuator (55) operably to translate a metallic component (C) such that an end portion (64) of the metallic component (C) is positioned within the aperture (38) of the build plate (26) and below the build surface (36). The apparatus (10) may further include a seal (28) coupled within the aperture (38) of the build plate (26) and configured to engage the end portion (64) of the metallic component (C). The aperture (38) of the build plate (26), the seal (28), and the end portion (64) of the metallic component (C) may cooperate to form a powder bed (60) to hold metallic powder (P) therein. The apparatus (10) may also include an external heat control mechanism (30) operable to form a predetermined temperature profile of the end portion (64) of the component (C) to prevent cracking of the component (C). Un appareil (10) de fabrication dun composant métallique (C) et des méthodes connexes sont décrits. Lappareil (10) peut comprendre une plaque de construction (26) ayant une surface de construction (36) et une ouverture (38). Lappareil (10) peut aussi comprendre un actionneur (55) fonctionnel pour déplacer un composant métallique (C), de sorte quune partie dextrémité (64) du composant métallique (C) soit positionnée dans louverture (38) de la plaque de construction (26) et sous la surface de construction (36). Lappareil (10) peut aussi comprendre un joint détanchéité (28) raccordé dans louverture (38) de la plaque de construction (26) et conçu pour attacher la partie dextrémité (64) du composant métallique (C). Louverture (38) de la plaque de construction (26), le joint détanchéité (28) et la partie dextrémité (64) du composant métallique (C) peuvent coopérer pour former un lit de poudre (60) pour retenir la poudre métallique (P). Lappareil (10) peut aussi comprendre un mécanisme de contrôle de la chaleur externe (30) fonctionnel pour former un profil de température prédéterminé de la partie dextrémité (64) du composant métallique (C) pour empêcher la craquelure dudit composant (C).
