Oak Ridge National Labs and Strangpresse Enter Into a Cooperative Research and Development Agreement (CRADA)

Youngstown, OH September 12, 2016 – The Department of Energy’s Oak Ridge National Laboratory (ORNL) and Strangpresse, LLC have entered into a research and development agreement to evaluate the Strangpresse extruder intended for large-scale additive manufacturing, as well as, conduct material testing for long fiber reinforced materials.

ORNL is leading advances in the production of large-scale 3D printed materials, refining industrial processes to decrease costs and increase efficiency.

Strangpresse has developed a new polymer extrusion system capable of processing in excess of 110 pounds per hour. Under the agreement, ORNL will validate the flow rate, system response time and linearity of flow, as well as identify processing parameters, make test articles and qualify material properties with a specific focus on long fiber reinforced polymers.

“We are excited to be teaming up with ORNL again,” said Strangpresse CEO Chuck George. “The processing of long fiber reinforced polymers is a game changer for additive manufacturing. The industry will no longer be comparing the strength of the part as it relates to the base thermoplastic polymer, but rather a factor related to the fiber strength.”.

Phase one of the project will focus on testing the extruder, beginning with the coordination of system requirements between the two companies. ORNL will then begin to integrate the Strangpresse extruder with a test apparatus and validate the physical, electrical and computational capabilities and fully characterize the extruder.

Once that is complete, ORNL will test and evaluate the Strangpresse extruder by selecting three long fiber reinforced thermoplastics to use in the full evaluation of the system. They will then manufacture test articles and measure material properties and conclude by creating a demonstration article.

The ORNL and Strangpresse collaboration is managed through a cooperative research and development agreement, and the project is supported by the DOE Advanced Manufacturing Office. Work is performed at the DOE Manufacturing Demonstration Facility at ORNL. Learn more about ORNL at

Strangpresse was founded in 2014 to research, develop, and commercialize fully controllable, lightweight, thermoplastic extruders to be used primarily in additive manufacturing. Strangpresse was the first company to license ORNL suit of patents associated with large scale additive manufacturing on a non-exclusive basis.

Strangpresse has also been contracted by Lockheed Martin Space Systems to provide an advanced extruder for use in their Multi-Robotic Additive Cluster Research and Development initiative. They are also working with Baylor University to develop extrusion equipment that meet their AM production and research needs, specifically related to long fiber orientation. The Strangpresse leadership team has over 70 years’ experience in the thermoplastic extrusion industry. In addition to its licensing agreement with ORNL, they have partnered with Rockwell Automation’s original equipment manufacturer team to continue its development of control and monitoring systems for its extrusion equipment.
