Abstract (en)
[origin: WO2022037933A1] The invention relates to an apparatus (100) for continuously producing moulded bodies (K1-K7) by means of an additive manufacturing method. The apparatus (100) comprises a processing region (2) and a separation device (3). The processing region (2) is designed to receive a powder, wherein a layer-by-layer processing of at least part of the powder to form moulded bodies (K1-K7) can be performed in the processing region (2) by means of the additive manufacturing process. The separation device (3) comprises at least one separation element (31a, 32a), which can be or is introduced into the processing region (2) in such a way that chambers (21, 22) are formed in the processing region (2). The separation device (3) has a drive (33) which is designed to move the at least one separation element (31a, 32a) in such a way that the chambers (21, 22) are lowered in the vertical direction during the layer-by-layer processing from a treatment portion (B1) of the processing region (2) to a removal portion (B2) of the processing region (2). In addition, the drive (33) moves the at least one separation element (31a, 32a) in such a way that the at least one separation element (31a, 32a) in the removal portion (B2) of the processing region is removed at least in part from the processing region (2) in such a way that a lower of the chambers (21, 22) is opened, so that the produced moulded bodies (K1-K7) fall or slide out of the processing region (2).
