The invention relates to a method for producing 3D shaped articles, in which method: a suspension comprising metallic, ceramic or polymer particle material or cement-bound materials is applied as a suspension layer to a construction platform to produce a layer; the layer thus applied is at least partially dried; a binder is selectively applied; and the selectively applied binder is solidified; these steps being repeated until the desired 3D shaped article has been obtained; where necessary, the particle material which has not been solidified by means of the binder is removed; and the 3D shaped article is unpacked; wherein the suspension for producing a layer is applied by means of a sieve plate, which is positioned onto the last applied layer on the construction platform and through which the suspension is applied to the last particle material layer; and wherein the sieve plate is removed again before the selective application of the binder.
