Solving shipbuilding and marine manufacturing challenges
Traditional casting and machining of large marine components can result in long lead times, high costs and supply chain delays. WAAM enables faster, more flexible production of large-scale metal parts.
Key benefits:
- Reduced lead times for large components
- On-demand spare part production or in-service repair
- Lower material waste
- Complex geometries without tooling
- Improved supply chain resilience
Large-scale additive manufacturing for marine components
DEEP Manufacturing delivers end-to-end WAAM solutions for large marine components, from design optimisation and process development to certified production. Our large-format systems enable the manufacture of complex, corrosion-resistant parts at scale, reducing lead times and simplifying supply chains for shipbuilding, offshore and marine engineering projects.
How DEEP Manufacturing delivers WAAM parts
From initial feasibility and design optimisation through to WAAM production, machining and inspection, DEEP Manufacturing applies a controlled, engineering-led process to every component. Manufacturing is carried out in line with DNV standards, supported by rigorous testing, quality assurance and full traceability.
High-performance materials for marine environments
Components are manufactured using corrosion-resistant alloys engineered for harsh marine conditions, delivering strong mechanical performance and long-term durability. DEEP Manufacturing works with stainless steels, nickel alloys and marine-grade materials, including nickel aluminium bronze, to meet demanding operational requirements.
Benefits of additive manufacturing for maritime applications
Additive manufacturing supports evolving maritime standards by enabling more efficient, resilient and responsive production of critical components.
Key benefits:
- Reduced lead times for large marine components
- On-demand manufacture of critical spare parts
- Lower material waste compared to traditional methods
- Production of complex geometries with reduced tooling
- Greater supply chain resilience and flexibility
- Reduced inventory through digital part storage
