A 3D-inkjet printing method includes the steps ofa) providing two or more fluids having a different composition to an inkjet printer; b) mixing the two or more fluids in a controlled amount; c) jetting the mixture of the two or more fluids with the inkjet printer onto a support; d) at least partially curing the jetted mixture by actinic radiation or electron beam; and e) repeating steps b) to d) in order to build a 3D-relief on the support. The method is capable of printing 3D-objects with inkjet fluid sets in an inkjet printer.
