METHOD FOR PRODUCING THREE-DIMENSIONAL CERAMIC MOULDINGS

摘要

A process for producing three-dimensional shaped ceramic bodies by layerwise printing of a suspension comprising the constituents required for formation of the shaped ceramic bodies by means of an inkjet printer in the desired two-dimensional shape onto a support material, drying and hardening of the layer composite formed, which is characterized in that printing is effected using a suspension comprising from 50 to 80% by weight of ceramic particles in a dispersion medium comprising an aqueous boehmite sol, at least one low molecular weight alcohol, at least one drying inhibitor and at least one organic fluidizer, and also an apparatus for carrying out this process are described.
