For the first time researchers at Lawrence Livermore National Laboratory (LLNL) have 3D printed aerospace-grade carbon fiber composites, paving the way for better control and optimization of the lightweight material that is stronger than steel.
…
However, the LLNL researchers reported printing numerous complex 3D structures using a customized Direct Ink Writing (DIW) 3D printing process. Lewicki and his team also created and patented a new chemistry that can cure the material within seconds rather than hours, and used the Lab”s high performance computing capabilities to build accurate models of the flow of carbon fiber filaments.
