The invention is directed to a method for the preparation of an energetic material product such as a propellant or explosive charge or grain. The method includes additive manufacturing with co-extrusion of at least two materials to form a multi-layered filament and layer-by-layer deposition of the multi-layered filament. The multi-layered filament has a first material layer and a second material layer and at least one layer includes an energetic material. In another aspect, the invention is directed to an apparatus for use in this method, the apparatus comprising a co-extrusion nozzle.

Printing of energetic materials

The invention relates to a method of generating a 'multicomponent particle comprising: and a multicomponent particle generating system comprising: a first nozzle constructed to generate at least one isolated particle; a second nozzle arranged to generate a generally uninterrupted fluid jet without breaking up, &#x2014;said first and second nozzles arranged to have said isolated particle collide with the fluid jet so as to combine said particle with fluid of the second fluid jet, for providing a multicomponent particle; and a collector by which said isolated particles can be captured after collision with the fluid jet.
