Abstract: A method is described for forming a body having at least one through-going passage, said method has the steps of:



a) providing a mixture comprising particles and at least one liquid pocket inside a curable matrix,
b) subjecting said mixture to a first alternating voltage having a first frequency to form a body in which said at least one liquid pocket extends from a first surface of said body to a second surface of said body thereby forming at least one through-going passage lacking curable matrix, and
c) curing said curable matrix into a cured matrix,
wherein at least some of said particles are located at an interface between said at least one through-going passage comprising liquid and said cured matrix.
