Thermwood LSAM


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.

The Details

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.    

Part after printing and trimming

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.

Much of the technology used in Thermwood's LSAM machines and print process is completely new. Thermwood has already received numerous patents on this revolutionary development and many more are in the works. Many exciting results that LSAM has already achieved are covered by non-disclosure agreements and must be kept secret.  LSAM is truly state-of-the-art in the exciting new world of large scale additive manufacturing.

Thermwood Signs Agreement with Navy's Fleet Readiness Center East

Thermwood Corporation

Thermwood Corporation of Dale, Indiana has signed a formal Cooperative Research and Development Agreement with Fleet Readiness Center East located at Marine Corps Air Station Cherry Point, N.C., and part of the Naval Air Systems Command, to conduct a two-year, joint technology development effort centered on Thermwood’s emerging Large Scale Additive Manufacturing (LSAM) technology.

Thermwood’s LSAM machines are large-sized industrial additive manufacturing or three-dimensional printing machines that are available in sizes up to 100 feet long. These systems use a “near-net-shape” approach for making parts in which parts are first 3D printed at high speed to a size slightly larger than needed and then trimmed to final net size and shape. Thermwood’s LSAM machine consolidates printing and machining on the same machine using dual gantries. Dual controls allow print and trim operations to be performed simultaneously, each on different ends of the table.

“We are excited to work with the FRC East and are confident that, working together, we can achieve significant advances and results,” said Thermwood Founder, CEO and Chairman Ken Susnjara. “I am confident that this program will benefit us both while further advancing the state of the art.”

Thermwood has been in a continuous research and development program developing additive manufacturing equipment and technology, and in September announced a line of large scale additive manufacturing systems called LSAM. The dual-gantry, high-wall machines are available in sizes from 10-foot-by-10-foot to 10-foot to more than 100-foot with print capability from 150 to 500 pounds per hour.
