A method of producing a multilayer body by coalescence, characterised in that the method comprises the steps of a) filling a pre-compacting mould with a start material in the form of powder, pellets, grains and the like, b) pre-compacting the start material at least once and c) compressing the material in a compression mould by at least one stroke, where a striking unit emits enough kinetic energy to form the body when striking the material inserted in the compression mould, causing coalescence of the material, d) at least one further material being inserted into the mould in the form of powder, pellets, grains and the like, either in step a), after compacting in step b) or after compressing the first material in step c), e) if necessary, further pre-compacting and/or compressing being performed after the insertion of the at least one further material.
