1. A pivoted powder pushing device (125) for bringing a portion of powder from a base surface (130) of an apparatus (100) for producing a three-dimensional object layer by layer using a powdery material which can be solidified by irradiation thereof with an energy beam and to a position between a distribution member (185) and a working area (190) of said apparatus, said pivoted powder pushing device (125) comprising:
a first portion (170), and a contact member (154), wherein: the contact member (154) is configured to operatively engage a grip arm (150) of the distribution member (185) when the distribution member (185) is positioned at least in part above the base surface (130), and the first portion (170) is moved via the engagement of the grip arm (150) and the contact member (154) in a first direction opposite a direction of travel of the distribution member (185), such that the first portion (170) of said pivoted powder pushing device (125) passes under said distribution member (185).
