    Thermwood Collaborating with the Navy to Explore Additive Manufacturing Technology

    Thermwood Corporation has entered into a collaborative program with the Naval Surface Warfare Center, Carderock Division to explore the use of additive manufacturing technology in developing marine models for ship and ship systems testing.

    Carderock Division is the U.S. Navy’s state-of-the-art research, engineering, modeling and test center for ships and ship systems. It is the largest, most comprehensive establishment of its kind in the world, serving a dual role in support of both our U.S. naval forces and the maritime industry. Navy and maritime communities have come to depend on their expertise and innovative spirit in developing advanced platforms and systems, enhancing naval performance, reducing operating costs and addressing the Navy’s evolving mission.

    This initial validation program was centered on printing an unclassified scale nose of a submarine using Thermwood’s LSAM additive manufacturing system. The part was printed using 20% carbon fiber filled ABS in 11 hours and 45 minutes using traditional horizontal layer printing and a 40mm melt core. Final trim required 5 hours. Both printing and trimming were completed on the same machine, using Thermwood’s 10’ x 20’ LSAM at its demonstration lab in Southern Indiana.

    Because of layer cooling requirements, the print rate for this part was less than half of the maximum rate the machine is capable of. It is expected that, moving forward, this program will include the printing of additional components using both horizontal and vertical layer printing.

    More Information on LSAM

    LSAM is based on exciting new technology developed from an entirely new direction.

    LSAM is intended for industrial production. It is not a lab, evaluation or demonstration machine, but is instead a full-fledged industrial additive manufacturing system intended for the production of large scale components.

    Thermwood has already applied for 19 separate patents on various aspects of this new technology (several have already been granted and more will be coming as development continues). LSAM is truly “state of the art” in this exciting new world of Large Scale Additive Manufacturing.

    About Thermwood
    Thermwood
    is a US based, multinational, diversified CNC machinery manufacturer that markets its products and services through offices in 11 countries. Thermwood is the oldest manufacturer of highly flexible, 3 & 5 axis high-speed machining centers known as CNC routers. Thermwood has also become a technology leader in large scale additive manufacturing of thermoplastic composite molds, tooling, patterns and parts with its line of LSAM (Large Scale Additive Manufacturing) machines that both 3D print and trim on the same machine.
