Abstract: The invention relates to a ceramic feedstock comprising the components a), b) and optionally c), wherein component a) is at least one ceramic material, component b) is at least one binder (B) and optional component c) is at least one additive (A). The ceramic feedstock is preferably provided in form of a filament to be employed in three-dimensional (3D) printing techniques, particularly in a FFF printing process. The inventive ceramic feedstock can, therefore, be successfully employed for the 3D printing of support structures and/or separation layers. Further, the invention also relates to three-dimensional objects as such, in particular three-dimensional green bodies, three-dimensional brown bodies or three-dimensional sintered bodies as well as to a process for the preparation thereof.
