The US-based company Chromatic 3D Materials announced the successful testing of rocket fuel produced using a 3D printer. During static fire tests at the IS4S range in Alabama, the material withstood a pressure of 1800 psi (approximately 124 atmospheres) while maintaining structural integrity. This is reported by Ixbt.com .
This development is based on Reactive Extrusion Additive Manufacturing (RX-AM) technology. This method allows for printing fuel in a liquid state, after which the material solidifies almost instantly. Unlike traditional methods, this approach eliminates the need for complex molds and time-consuming curing processes.
The main advantage of the technology lies in the ability to freely design the internal shape of the fuel channel. It is this channel that determines the engine's combustion characteristics and thrust. 3D printing makes it possible to create complex geometric shapes that are impossible to achieve with traditional methods.
Representatives of Chromatic stated that they did not create an entirely new type of fuel, but rather adapted existing compositions to their printing technology. This approach is generating significant interest not only in the space sector but also in the defense industry.
Company CEO Cora Leibig emphasized that additive manufacturing will increase the efficiency of many US rocket systems. In the future, this technology is expected to pave the way for creating more powerful and long-range engines.
