MIT-developed 3D printer can output a fully functional electric motor in a single process
3D printing the fuel also eliminates the long cure times and the need for complex tooling characteristic of solid fuels, making rocket production faster and more agile — an always-welcome description for the defense supply chain.
Although several 3D printing techniques have proven capable of matching their formative manufacturing counterparts in finished product strength, there were concerns about whether the 3D-printed fuel could withstand the immense pressure of launch. In the recent test, fuel proved that it can indeed handle the heat of a real launch — literally. According to Chromatic, “the propellant achieves energetic loading levels comparable to top-performing conventional propellants while delivering the structural integrity required to withstand high-pressure combustion environment.”
Beyond matching the capabilities of conventional propulsion systems, Chromatic’s technology unlocks new performance possibilities. Integrating propellant directly into structural components allows the company to reduce unnecessary mass, create more efficient internal geometries, and precisely tailor thrust behavior in ways that are difficult or impossible with traditional manufacturing methods.
Another possibility is 3D printing different types of fuel in the same rocket, to vary speed and thrust at different stages of flight. The result of these possibilities could be lighter propulsion systems with higher performance, longer range, and greater operational flexibility for future missions.
“These results demonstrate that additive manufacturing is not only viable for defense propulsion — it can drive meaningful performance gains across at least 90% of the U.S. rocket arsenal,” said Dr. Cora Leibig, Founder and CEO at Chromatic 3D Materials. “We’re showing that it’s possible to maintain compatibility with existing systems while opening the door to rockets that fly farther, hit harder, and can be produced faster.”
As defense supply chains come under growing pressure, Chromatic’s manufacturing approach could offer a more flexible and resilient alternative. By allowing rocket propellant to be produced on demand and closer to the point of need, RX-AM reduces reliance on large, centralized production infrastructure and long logistics chains. 3D printing technology continues to offer performance advantages beyond conventional systems. Last year, Korean engineers managed to 3D-print a titanium fuel tank for space travel.
