Three-dimensional printing of energetic materials: A review

Additive manufacturing technology or three-dimensional (3D) printing has been applied in many manufacture fields. The combination of 3D printing and conventional energetic material fields can create sufficient space for preparing and molding of energetic materials. Although recent advances in this field are encouraging, with the printing technologies offering many merits over the traditional fabrication technologies, some application principles and material considerations should be discussed. This review summarizes some of the significant advances in this evolving field over the past few years, lists the typical application cases, discusses the current challenge, and presents the possible future development trend.
