An apparatus and method to magnetically align fibers in a base additive material during an additive manufacturing process for material property enhancing purposes or to facilitate joining of multiple types of materials during the additive process to form an integrated part. The magnetically alignable fibers are positioned through the application of a controlled, multi-axis positioning magnetic field during the additive-material layer deposition phase. This allows the fibers to be embedded within the base additive-material in any three-dimensional desired orientation, and the orientation to be varied from layer to layer, to permit directional enhancement of material properties, dependent on the nature of the fiber materials themselves. Likewise, joining of multiple types of materials may be improved through the controlled deposition of such fibers embedded within the base material itself during the additive-process between layers of two or more dissimilar materials, to provide a directionally aligned mechanical attachment between layers of base additive materials to result in a strengthened consolidated part at the conclusion of the additive manufacturing process.
