The purpose of this study is to develop a pyrotechnic initiator ink that can be used accurately in additive manufacturing. The initiator ink must be able to ignite a less sensitive energetic material and should demonstrate multi-point or simultaneous initiation. Thermites have a high thermal output with low gas emission and are the ideal energetic for the ink. Three thermite formulations are developed using barium nitrate, strontium nitrate, or manganese oxide as oxidizers and Al as fuel. The oxidizer and fuel mixture is combined with a stoichiometric mixture of Fe and S to help stabilize and control the burning of the thermite. The combustion rate and thermal output of each formulation is tested. The barium nitrate and strontium nitrate formulations were found to have the highest burn rate and thermal output. Future experiments include testing the volumetric flow rate and viscosity of the ink in an additive manufacturing application.
