We have developed a novel extrusion-based 3D printing technique that can achieve a resolution of 0.51 mm layer thickness, and catalyst loading of 44% and 90.5% before and after drying, respectively.

We proposed and developed a carbon nanofiber (CNF) suspension-based sizing agent, that resulted in improved interfacial, and mechanical properties. The CNF dispersed sizing agent can be applied in a relatively simpler way (by passing the continuous tow through it).

The technologies polymer cellulose nanocomposite mats and process for making same.

As additive manufacturing technologies advance and 3D-printers get larger, there is a constant need for larger extruders with higher throughput to construct larger objects at reasonable time.
