Printable energetic materials

Digital 3D additive manufacturing (AM) techniques enable the formation of complex solid objects, which are sometimes difficult to produce using conventional techniques. Printing technologies influence product price, logistics and availability, and can be used for printing tools as well as consumables, among them propellant devices and other energetic materials. The motivation for developing such new energetic materials and devices is clear; these can be made on demand, close to their consumption site in geography and time, thereby simplifying logistics. Furthermore, 3D printing techniques of energetic materials offer spatially resolved control of morphology, density, compositional grading and the characteristics of the 3D printed polymers, such as elasticity.

We develop and characterize different photo-curable energetic monomers¹ and their 3D printing into energetic materials and energetic devices.
