Additive and shaping processes

The additive and shaping processes team specialises in functional prototyping and layered manufacturing via the laser direct metal deposition (powder fusion) and wire deposition processes.

Main projects

Additive and Shaping Processes

The team is currently working under EPSRC and EU FP6 grants to model microstructure and stress control in LDMD, develop wire deposition and coincident wire-powder processes and examining ways of improving the efficiency of the LDMD technique both as a manufacturing and repair tool.

A completed project has also examined laser-induced stress forming of pipes and ways of optimising it through scan strategy.
