Title: 3D PRINTING OF FIBROUS STRUCTURES
Abstract:
Methods and apparatuses for printing a three-dimensional fibrous structure are disclosed. A fibrous layer is printed onto a printing surface by forcing fibers through at least one extrusion die and onto the printing surface. The extrusion die and/or printing surface are moved in the X, Y, and/or Z direction while printing the fibers.
