A PROCESS FOR THE PREPARATION OF A MULTI-PHASE COMPOSITE 3D OBJECT

Abstract: a process for the preparation of a multi-phase composite 3d object comprising the core and shell, which comprises: (a) generating data of the core and shell of a 3d model of the 3d object; (b) building the core of said 3d model from at least one first composition and building the shell of said 3d model from at least one second composition according to the data generated, wherein the core is built by dispensing the at least one first composition from a first dispenser, and (c) solidifying the at least one first composition and the at least one second composition to obtain the multi-phase composite 3d object, wherein the solidified material of the at least one first composition and the solidified material of the at least one second composition have different properties.
