Auburn upgrades hypersonics research with CF3D composite 3D printing cell

Auburn University is expanding its capabilities in the additive manufacturing of fiber composite structures and has commissioned a CF3D Enterprise cell from Continuous Composites at its Research and Innovation Campus in Huntsville. The system complements the existing infrastructure for hypersonics research and is intended in particular to address components for aerospace and defense applications where temperature resistance and structural efficiency are critical.

CF3D (Continuous Fiber 3D Printing) combines robot-guided path control with the placement of continuous fiber tows in a matrix. In conjunction with the CF3D Studio control and programming environment, researchers can generate load-path-optimized laminate structures that differ significantly from conventionally laminated layups or short-fiber-reinforced 3D-printed parts. For hypersonic systems, in which thermomechanical loads vary greatly, such tailored fiber architectures are an important building block for lighter load-bearing structures and integrated functional zones.

The site in Cummings Research Park is located in the immediate vicinity of Redstone Arsenal and numerous aerospace companies. The CF3D cell is embedded there in Auburn’s Applied Research Institute, which offers flexible laboratories, simulation environments, and secured research areas.

“Huntsville continues to be the gravitational center of hypersonic development in the United States, and Auburn is investing where it matters,” said Steve Starner, CEO of Continuous Composites. “The addition of a CF3D Enterprise cell gives Auburn and its partners a modern composite manufacturing capability and a toolset to explore structural concepts that were previously out of reach.”

For the university, CF3D is both a research platform and a training tool. Students and doctoral candidates gain direct access to digital composite manufacturing and can link design data, process parameters, and test results into closed development cycles.

“Auburn’s presence in Huntsville places us in the center of national-priority programs,” said Luke Boyer, Ph.D., Lead Principal Research Engineer and Advanced Manufacturing Team Lead. “Integrating CF3D into our capabilities expands our support for hypersonic development and gives partners the ability to study structural concepts grounded in real manufacturing data.”

With the planned CF3D Tech Tour in March 2026, Continuous Composites aims to deepen the exchange between OEMs, research institutions, and government representatives. For Auburn, the investment strengthens the role of the campus as an interface between university research, defense-related industry, and the practical implementation of complex 3D-printed composite structures.
