Introduction Manufacturing of products from a powdered substrate is well established within the metallurgical industries. Processing usually involve the dense packing of a powder into a die or mould which can then be subjected to sintering through compaction and/or heating. More recently the technique of Additive Manufacture (AM) has also made use of powder materials to create products through the layer by layer deposition/application and precise, localised fusing of a feedstock to itself through, for example, laser sintering or electron beam melting.
