Abstract (en)

[origin: WO2019238533A1] An apparatus (1) for producing three-dimensional objects (2) from a deformable material (4) has the following features: a housing (3) that has a chamber (21) for receiving the deformable material (4); a feed device (5) for feeding the deformable material (4) into the chamber (21) of the housing (3); a first discharge opening (7) for discharging the deformable material (4) from the chamber (21) of the housing (3); a first closing device (8) for selectively closing and opening the first discharge opening (7), said device having a cavity (22) connected via at least one connecting bore (23) to the chamber (21) of the housing (3); a second discharge opening (11), which has a smaller cross-section than the first discharge opening (7), for discharging the deformable material (4) from the cavity (22) of the first closing device (8); and a second closing device (24) for selectively closing and opening the connecting bore (23).
