Abstract Scope Additive Manufacturing (AM) of polymer composites has proven to be a fantastic tool for prototyping. However, replacing the traditional manufacturing process with AM is still far-sighted. The main hurdle is the low mechanical properties of 3D printed parts due to high porosity. However, AM has a unique capability to align the fibers in the deposition direction. By controlling the deposition direction, preferred fiber alignment can be achieved, which affects the mechanical properties of the printed part. Oak Ridge National Laboratory (ORNL) has developed a new manufacturing process, where the AM printed preform is followed by a traditional compression molding (CM) process. This work studied various parameters such as extrusion rate (V) and nozzle sizes (D) to understand the fiber alignment and porosity and their effect on the mechanical properties prepared via the AM-CM process. High mechanical properties with increased V/D ratios are observed.
