The use of 3D printing for the fabrication of flexible linear shaped charges

Abstract. The present research present the use of FDM additive manufacturing, in the FGF (fused granulate fabrication) mode to produce the shaped explosive materials used in the production of flexible linear shaped charges. Insights into the preparation of composite energetic material and the printing process are presented, together with rheological characterization, numerical simulation and performance testing. The results show that additive manufacturing represent a promising manufacturing technology in the shape optimization process.
