This dissertation focuses on the science and engineering of 3D printing of epoxy-carbon nanotube-based nanocomposites. The main goal is to develop new ink materials for 3D printing of conductive nanocomposites as well as to understand the materials and properties through simplified theoretical modeling. First, an epoxy-nanoclay-carbon nanotube ink is developed that is electrically conductive (2.2 * 10-6 S/m) and improves mechanical strength by 30-60%. Then, an epoxy-carbon fiber-carbon nanotube ink is developed, which improves mechanical strength and modulus at least by 2-fold and improves electrical and thermal conductivities (10-2 S/cm and 0.3 W/m K). Last, based on the modified rule of mixtures and the laminate analogy method, a theoretical model is developed to relate the properties of the nanomaterials to the collective properties of the 3D printed materials. The explored combination of the materials applies to a wide range of applications from aerospace to electronics. The developed science sheds light on the 3D printing of thermosetting nanocomposites and aims to advance the field of additive manufacturing of nanomaterials.
