Aerospace-Grade Carbon Fiber Composites 3D Printed for First Time

Lawrence Livermore National Laboratory researchers are now the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the super lightweight and strong material. The researchers printed several complex 3D structures through a modified direct ink writing (DIW) 3D printing process. They also developed and patented a new chemistry that can cure the material in seconds instead of hours, and used the lab's high-performance computing capabilities to develop accurate models of the flow of carbon fiber filaments.
