Item Characterization of In-Situ Conductive Paste Extrusion on PolyJet Substrates(University of Texas at Austin, 2014) Perez, K. Blake; Williams, Christopher B.The integration of Direct Write technologies into Additive Manufacturing system enables the in-situ deposition of conductive traces during part printing, and thus the creation of parts with embedded electronics. In this paper, the authors detail their research of integrating an extrusion-based direct write system into a PolyJet material jetting system to create multimaterial products with structurally integrated, functional electronics. An investigation of the dispensing (e.g. orifice diameter, dispense pressure, and toolhead speed), drying (e.g., time and temperature), and substrate parameters (e.g., VeroWhitePlus and TangoBlackPlus) on the geometry of the deposited trace is presented. Additionally, the adhesive compatibility of the conductive material on both rigid and elastomeric PolyJet substrate surfaces is investigated by measuring wet and dry contact angles.
