WAM® combines an electric arc with certified welding wire, as feedstock, to produce medium to large scale, free-form parts.

Our patented WAM® process is characterised under the 3D printing standards for Direct Energy Deposition. It challenges other wire-feed-stock metal printing techniques such as Electron Beam, Wire Fed Laser and Laser sintering processes. Unlike these different processes, WAM® can be used to print metal parts in an open free-form fabrication environment using localised inert gas. With localised gas shielding, the need for an enclosed chamber of any kind is eliminated, which does not limit the component build size. Various gas mixtures, controlled cooling can be used to enhance the properties of the final part.

Wire Additive Manufacturing greatly reduces fabrication costs, with the process and proprietary software improving manufacture lead times while improving material properties.

When our technology is combined with an ARCEMY® print module or a hybrid production cell, it is capable of deployment at a much lower capital cost than alternative additive manufacturing processes.

WAM® is highly innovative, removing the traditional size restrictions of 3D printing and substantially reducing high-cost material waste while minimising fabrication time compared with conventional casting, forging and machining.

The size of the product does not limit WAM® as it builds free-form without an enclosed chamber, hence not restricting size. Further, with the broad range of metals available, WAM® can either repair or create a new 3D model to manufacture an entirely new component without relying on the current series of supply chain involvement.

Material Diversity

Materials used

An extensive array of metals and alloys is available to fabricate parts using our patented WAM® process and ARCEMY® print module.

Our process is highly adaptable to virtually any material, often resulting in superior property outcomes resulting from the Direct Energy Deposition (DED) process.

For additional properties, parts can be heat-treated, coated or used as a feature addition, supporting traditionally manufactured parts.
