This method can allow for more freedom of part design with regard to complexity of shape, and can reduce material waste compared to other manufacturing methods. This project explores the 3D printability of common caulking materials, cements, adhesives, and other pastes. These materials are low-cost and present high printability. Experiments are underway to determine the thermomechanical properties of these 3D printed materials and the effects of nanomaterial additives in low loading (1% by weight or less) in these materials. The additives being tested are carbon nanotubes, graphene oxide, and silica nanoparticles. They have the potential to improve the thermal and electrical conductivity of these materials as well as the thermomechanical properties. Aging studies using high temperature, pressure and moisture are being utilized to test the long term viability of these materials as well. Show less
