Abstract
Fused filament fabrication (FFF) is a 3D printing technology that transforms digital designs into three-dimensional objects made of thermoplastics. Presently, there is an unmet demand to translate this technology into a full-scale manufacturing process. With advancements in hardware designs and build preparation software, the main component that has been holding back progress in 3D printing industry is the filament material. The majority of the plastic filaments in the market lack high-performance characteristics like high strength, durability, and electric conductivity. Reinforcing the standard plastic filaments with a strong multifunctional nanomaterial-like carbon nanotubes (CNT) will drastically improve the capabilities of 3D printed parts. In this research, a filament production system was developed to produce a new type of filament that incorporates CNT yarn. This filament was analyzed under the microscope to characterize its printability. A small plate was successfully 3D printed to demonstrate the use of CNT yarn filaments.
