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.
