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).
