Lyman-Morse has begun construction of a new 15,000-square-foot facility to support large-scale composite fabrication and assembly, marking a significant expansion of the company’s manufacturing facilities in Thomaston, Maine. The new building will be the third facility on the campus and will hold the company’s Advanced Composites Center. It joins the Lyman-Morse Workboats division, and Lyman-Morse Technologies building, which houses the company’s CNC and metal additive department.
Together, these three facilities position Lyman-Morse as a fully integrated advanced manufacturing partner capable of delivering across multiple materials and disciplines. This combination allows Lyman-Morse to support a wide range of applications, from marine systems and vessels to industrial components and specialized engineered solutions.
With the addition of the Advanced Composites Center, Lyman-Morse continues to broaden its capabilities across:
- Rapid Prototyping
- Composite fabrication and structural components
- Metal additive manufacturing – 3D printing SS316L
- Custom-engineered systems and assemblies
Purpose-built to support the company’s advanced composites capabilities, the new clear-span building includes a radiant-floor heat system to provide consistent climate control for construction projects and teams. Integrated compressed air lines, vacuum pumps, and IT infrastructure support the modern tools and equipment used in composite manufacturing, and two 5-ton overhead cranes will enable efficient movement of large structures throughout the building. A planned renewable energy system will enhance Lyman-Morse’s commitment to sustainability and environmental responsibility. The interior layout is engineered for flexibility, allowing teams to manage complex manufacturing projects while maintaining precision and efficiency across all stages of production. The new building represents a major step forward in Lyman-Morse’s scale, efficiency, and technical capacity as demand increases across the marine, industrial, defense, and specialized fabrication sectors.
“This expansion is about giving our team the space and infrastructure they need to execute at the highest level,” said Samir Gupta, manager of Lyman-Morse’s Advanced Manufacturing division. “This new building allows us to take on larger, more complex projects with greater efficiency.”
The project is supported by an award from the Maine Technology Institute’s Maine Technology Asset Fund (MTAF3.0), a state program that aims to boost economic activity and grow the state’s innovation economy. When completed in summer 2026, the ITAR-compliant Lyman-Morse Advanced Composites Center will join Lyman-Morse’s two other specialized manufacturing facilities on Elltee Circle and create a fully integrated, world-class hub for innovation in advanced manufacturing, metal and composite fabrication, and technology development.
The two other Lyman-Morse facilities on Elltee Circle that comprise the Advanced Manufacturing Campus include:
- Lyman-Morse Technologies
- Precision CNC machining operations, utilizing 3- and 5-axis machines
- EOS M290 metal additive manufacturing system
- Workforce training and development
- ITAR compliant
- ISO9001:2015 certified
- Lyman-Morse Workboats
- Construction of aluminum workboats, landing crafts, and emergency response vessels
- Specialized production of commercial and government vessels
- Aluminum, Stainless and Carbon Steel fabrication with full finish coatings
- Standards: ABYC, ASME IX, AWS, ABS, AISC, NAVSEA, DEP
- In-house AWS certified welding inspectors (CWI) and certified welding educator (CWE)
- AWS D1.2 certified team of welders in marine specific alloys – 5086/83, 6061, 5052
- ISO9001:2015 certified
By bringing together composites, metals, and additive manufacturing within a single campus, the Lyman-Morse Advanced Manufacturing Center is positioned to support increasingly complex projects while maintaining the craftsmanship and problem-solving approach that has defined the company for nearly half a century. The expansion reflects Lyman-Morse’s ongoing investment in advanced manufacturing infrastructure, workforce development, and domestic production capabilities.
“This project is about building capability for the long-term,” said Drew Lyman, president of Lyman-Morse. “We’re creating a facility that not only supports our current work but positions us for the next generation of manufacturing challenges.”
