| Abstract Scope |
Aerosol jet printing offers digital fabrication of functional nanomaterials from liquid-phase inks. By combining two distinct aerosol streams in line within the printhead, multiple materials can be printed simultaneously from the same nozzle, allowing in principle fabrication of patterns containing a composition gradient. This presentation will highlight recent efforts to better understand this multimaterial printing capability, including the influence of ink formulation and printhead geometry on mixing uniformity. In one example, a nanoscale thermite containing aluminum and copper oxide nanoparticles was patterned, allowing microscale fabrication of energetics without upstream mixing to accommodate safety concerns in materials processing. In a second example, two distinct carbon nanomaterials were combined during printing to tailor electrical conductivity, including the demonstration of a graded pattern by dynamically changing the ratio of materials during patterning. This offers a compelling platform to fabricate more sophisticated structures with high resolution, digital control, and broad materials compatibility. |
