In the 18 months since launch, DEEP Manufacturing has grown into a fully DNV-approved wire arc additive manufacturer for PVHOs, building a facility capable of taking a large-scale metal component from print through to a certified, service-ready part on a single site - a milestone the company says reflects the market arriving at where the industry was always heading, rather than a surprise shift in demand.

Since launching in January 2025, DEEP Manufacturing has grown from a single site to two facilities in Bristol and Houston, moving into 24/7, DNV-approved certified production. Components including hemispheres, cylinders, propeller blades and material development blocks have already been delivered to customers, while its material portfolio has expanded to include carbon steel, stainless steel (ER316LSi), duplex and super duplex (UNS S32750), nickel aluminum bronze (ER CuNiAl), copper alloy (ERCuNi30) and aluminum (ER2319/2219).

That growth has been backed by new CNC machining capability, its next-generation Rollerbot 2.0 system and additional WAAM robots at Bristol, allowing components to move from first pass to final certification on-site. For customers across defense, aerospace, energy and maritime, that means lead times of up to three times faster than casting or forging, without compromising on the certification required for safety-critical components.

Reaching DNV-approved certified production within 18 months also separates DEEP Manufacturing from businesses that can print large-format components but cannot qualify and sign them off themselves - an increasingly important distinction for customers operating in high-integrity environments.

Peter Richards, CEO at DEEP Manufacturing, said: “We’re not seeing a spike in demand for large-format additive manufacturing. We’re seeing the market arrive at where we always believed it was heading.

“The question was never whether this shift was coming, it was who would be ready to meet it. Eighteen months ago, this was a single site and an idea. Today it’s a facility that can take a component from design to raw print to a certified part ready to ship. That’s not just growth for us - it tells you how quickly this market has moved, and we’ve built to meet it.

"The next stage of growth is more systems, more sites, and pushing WAAM further into industrialization, without ever compromising on the certification our customers depend on."

The Bristol facility now produces large-format components at scale. That combination of scale and in-house certification is central to how DEEP Manufacturing positions itself against traditional casting and forging routes, where those stages are typically split across multiple suppliers.

The Bristol growth sits alongside DEEP Manufacturing’s expansion into the US earlier this year, with a new facility in Houston, Texas, backed by parent company DEEP’s $100 million investment in a permanent engineering and development hub in Florida. Together, the two sites give DEEP Manufacturing large-format, certified manufacturing capability on both sides of the Atlantic.

Peter added: “Bristol and Houston aren’t two separate stories - they’re the same one, told on both sides of the Atlantic. Customers in defense, energy and maritime need this capability wherever they’re building, and that’s exactly what we’ve set out to deliver. The first 18 months were about proving this works. From here, it's about proving how far it can scale.”
