A Purdue team has taken advantage of the “boom” of 3D printing to create a 3D-printed “boom”… energetic materials that can safely be deposited using any commercial 3D printer. By suspending aluminum in a fluoropolymer, and adjusting print speeds and layer heights, they can used fused deposition modeling to print pyrotechnics, explosives, and propellants safely and accurately.
