Chromatic 3D materials, an advanced 3D printing materials company, recently announced it had successfully static-fired tested its 3D-printed rocket propellant. The tests, which took place at the integrated solutions for systems (IS4S) test range in Opekia, Alabama, demonstrated that the company's propellant can withstand over 1800 psi of combustion pressures without structural failure. The company describes the development as a “critical milestone in advancing resilient, next-generation propulsion manufacturing for rockets and defense applications.”

Rocket propellants , the high-energy material rocket engines combust and eject to produce thrust, are generally classified by their physical state as liquid, solid, hybrid, and gas — each with its own benefits and drawbacks.…
