Fundamentals of Direct-Ink-Writing<\/h3>\n<\/header>\n

\"\"<\/a>Direct-Ink-Writing (DIW) is an extrusion-based additive manufacturing method heavily utilized in meso- and micro-scales. In DIW, the liquid-phase “ink” is dispensed out of small nozzles under controlled flow rates and deposited along digitally defined paths to fabricate 3D structures layer-by-layer. Our research focuses on various key fundamental questions about the process:<\/p>\n

    \n
  1. What thermofludic mechanisms govern the flow and deposition of the inks?<\/li>\n
  2. How are these mechanisms determined by the material properties and process parameters such as printing speed, nozzle-substrate distance, flow rate etc.?<\/li>\n
  3. How do these mechanisms impact the printed part properties including their geometry, micro-structure, electrical and thermal conductivities and mechanical properties?<\/li>\n
  4. What are the key factors impacting process accuracy, resolution, repeatability and throughput and how can these factors be controlled?<\/li>\n<\/ol>\n

    We study the DIW of a wide variety of materials with drastically different properties leading to drastically different process mechanisms. We primarily focus on:<\/p>\n

      \n
    1. Polymer nanocomposites consisting of a polymer matrix and nanoparticles including carbon based ones such as carbon nanotubes, graphene flakes.<\/li>\n
    2. Hydrogels<\/li>\n
    3. Alloys and pure metals with melting points up to 700 degrees Celsius<\/li>\n<\/ol>\n

      See below videos demonstrating on DIW of different materials. For further details check out our recent publications below:<\/p>\n
