Continuous fiber bone screw and method of manufacture

A bone screw, comprising:

• an elongate part having a longitudinal axis extending in a longitudinal direction from a first end to a second end of the bone screw, and comprising:
• a base substrate extending between the first end and the second end, and along the longitudinal axis;
• and
• a plurality of continuous fiber layers disposed on the base substrate such that each of the continuous fiber layers at least partially surrounds the base substrate;
• wherein first layers of the plurality of continuous fiber layers comprise helical continuous fibers and define at least part of a first portion of an exposed thread pattern of a shaft of the bone screw;
• wherein second layers of the plurality continuous fiber layers define a second portion of the exposed thread pattern that is longitudinally offset or spaced apart from the first portion of the exposed thread pattern, the second layers comprising fibers oriented in a direction relative to the longitudinal axis that is different than an orientation of the helical continuous fibers of the first layers;
• wherein a distance between the helical continuous fibers in a first one of the first layers is different than a distance between the helical continuous fibers in a second one of the first layers;
• and
• wherein the plurality of continuous fiber layers comprises an alternating sequence of a first layer type and a second layer type, at least one of the first or second layers being of the first layer type including continuous fibers that are diagonally oriented at about +45 degrees with respect to the longitudinal axis, and at least one of the first layers or a third layer being of the second layer type including continuous fibers that are diagonally oriented at about-45 degrees with respect to the longitudinal axis.
