One of the most popular additive manufacturing (AM) processes is based on polymer extrusion using a continuous filament as feedstock. However, the use of this type of feedstock increases costs and narrows the variety of materials that can be used. The development of technologies that allow polymer pellets to be processed as feedstock would increase the popularity of polymer extrusion by addressing these two issues. This work describes the development of a piston-driven extrusion head that can… Expand
