Apparatus for fabricating a three-dimensional material comprising: a. means for orienting a cluster of filaments in a direction defining the Z axis and adapted to space such filaments in intersecting rows lying in directions defining the X axis and Y axis of the cluster, b. a first plurality of needles positioned adjacent said Z axis filaments orienting means and adapted to weave courses of filaments into the Z axis filaments along the X axis of said filaments, c. a second plurality of needles positioned adjacent said Z axis filaments orienting means and adapted to weave courses of filaments into the Z axis filaments along the Y axis of said filaments, and d. said Z axis filaments orienting means and said first and second pluralities of needles being sized and positioned to weave each of such filaments in close touching contact with each adjacent filament.
