We’ve seen 3D-printed rocket engines, but what about 3D-printed rocket fuel? Florida-based Rocket Crafters, Inc. (RCI) has been awarded a patent for a method of fuelling hybrid liquid/solid rockets using 3D printing technology. The company claims that the process ensures the fabrication of flawless, high-performance, safer-handling fuel grain. It will enter service in 2019 for launching satellites.
