Additive manufacturing compression molding, or AMCM, uses short-fiber-filled polymer and continuous fiber to print directly onto a mold with precise orientation to make parts such as propeller blades or battery boxes.
Compression molding then turns the print into an accurate finished piece. ORNL researchers proved AMCM significantly reduces time and cost by producing 100 parts in five hours, with each piece taking less than three minutes to print.
"By combining the fiber control of additive with the low porosity of compression molding, we can enable the high-volume production of next-generation composites," ORNL's Vipin Kumar said. "The mobility and aerospace industries need these lightweight materials to improve the energy efficiency of their applications."
