• Additive manufacturing (AM) has come to be considered one of the must
  groundbreaking technologies nowadays, revolutionizing the traditional manufacturing
  and opening the doors to a new generation of complex freeform
  engineered functional part. The AM process shows a high correlation between
  material, design, and the manufacturing process. This relationship offers the
  possibility to tailor and engineer localized material properties within one part.
  Currently a number of AM processes are available to deliver tailored mechanical
  properties through multi-material printing. In this work a novel integrated
  material-manufacturing-control system to print parts with functional
  Ferro-magnetic properties is presented. The proposed AM system, based on
  material jetting, photo polymerization, real time control system, and active
  magnetic alignment control allows the manipulation of the local orientation of
  a specialized photosensitive magnetically responsive resin to fabricate objects
  with locally controlled anisotropic particles arrangement. The proposed system
  builds upon the standard slicing and path planning algorithms used by
  open source 3D printing software and extends it by adding two extra dimensions
  related to the orientation of the magnetic particles within the printing
  process itself enabling the real-time control of the particles orientation of the
  printed parts.
