  • Additive manufacturing composites with flow induced fiber alignment
    Patent number: 12179415
    Abstract: Suspending fibers within a substantially similar direction within flow field allows for an even dispersion of fibers in a manufactured composite. The flow field can be established within a resin tank so as to control orientation of the fibers. An advantage of this approach is that fiber orientation can be changed layer by layer during printing. No matter where the reinforcements need to be, the fibers can be aligned on the fly to accommodate. 3D prints can made stronger for a very wide range of objects and opportunities.
