| description | The invention is directed to a method for the preparation of a propellant charge or grain, and to uses of the propellant charge or grain.The method of the invention comprises additive manufacturing of multiple distinctively identifiable print layers to produce a layered propellant charge or grain, wherein two or more of said layers each comprise at least one energetic material and a liquid curable binder, wherein the linear burn rate of an energetic material in a first layer is different from the linear burn rate of an energetic material in a second layer, and wherein each of said layers has a layer thickness in the range of 1-2000 µm, wherein said additive manufacturing comprises layer by layer curing of liquid curable binder material by radiation. |
