A technology driven company providing comprehensive integrated technical solutions in the field of wire-based directed-energy-deposition additive-manufacturing

Who we are

WAAM3D was incorporated in 2018 to commercialise Cranfield University's intellectual property in the field of wire-based DED AM. Prof Stewart Williams has been working in this field since the '90s, later on also with the added support of Dr Jialuo Ding and Dr Filomeno Martina, and the rest of the research team at the university.

The three co-founders have developed extensive industrial relationships within the WAAMMat programme, and have listened to industry's request to translate the research results into commercial products. Despite proven business benefits, the lack of supply chain has hindered the deserved industrial adoption of WAAM processes.

WAAM3D sets out to create such supply chain, leveraging on decades of experience in each area of industrial implementation: thorough knowledge in processes, dedicated software tools, purposely designed hardware, raw materials, training and services – giving the first integrated commercial offer via a dedicated industrial ecosystem.


To provide all the necessary tools and technical solutions needed for widespread adoption and exploitation of wire-based AM through a coherent ecosystem that responds to every users needs for the implementation of wire-based AM.


To be the world-leading company for wire-based AM processes, and to have them in every industry and research organisation around the world.


Integrity, punctuality, value creation, courage, commitment.


The combination of an electric arc or a laser as heat sources, and metallic wires as feedstock is referred to as Wire-bAsed Additive Manufacturing (WAAM). These processes have been investigated for AM purposes since the 1990s, although the first patent was filed in 1925. 


Motion is typically provided by robotic arms or by CNC gantries, benefitting from the flexibility and scalability of these platforms. Multiple robotic arms can be combined together to deploy multiple processes simultaneously, and/or to achieve ever larger part sizes and higher deposition rates.

The inherently higher deposition rates achieved with WAAM processes make them suitable for large-scale engineering components, which can be printed in a timely manner, with reduced manufacturing waste and minimised cost.

The availability of multiple processes (arc, laser, hybrid, multi-energy-source), each with different characteristics, ensures the alignment between your business needs and the capabilities of one of our systems.


Reduction in manufacturing costs

Through a combination of business improvements, metallic parts are cheaper than before.

Reduction in manufacturing waste

From near-net-shape to finish-machined, with little to no swarf.

Simplified supply chain

No decoupling points, local alternatives to metal parts sourcing.

Improved properties

Multi-material parts, or superior strengths by using our patented in-process cold-work solutions

Elimination of fabrication

Combine multiple parts in one, designed for AM

Reduction in lead times

Thanks to part consolidation, or to the elimination of forging operations, or to much less machining, parts can be procured much more quickly



Flexibility and cost-effectiveness for small batches of high-value products

Commercial aviation

Structural components in titanium alloys, special steels, and aluminium, with less machining waste and more competitive prices


Mission-critical metallic parts at a fraction of the cost, without compromising integrity


A manufacturing process of the future for the future of energy production


Large-scale metallic parts made locally, with lower non-recurring costs and improved properties

Oil and Gas

More manageable supply chains, with shorter lead-times for high-value products, more easily accessible spare parts, and less reliance on fabrication
