Abstract
Additive manufacturing methods and apparatus are described for the direct, automated, tooling-less fabrication of composite parts with complex shapes such as fiber-reinforced composite parts with isotropic properties. In some embodiments, fibers parallel to one axis (e.g. Z) are provided initially (e.g., as a preform) and layers are fabricated by selectively curing a resin around these fibers while adding other fibers with other orientations. In some embodiments, fibers are rendered substantially transparent by immersing them in a refractive index matching liquid, thus allowing selective curing of a resin in the presence of the fibers.
