The forming of the metal component is disclosed, in which feed material is initially in a powdered state. A sacrificial positive model (102) of a component is created and a negative mould (104) is built around said positive model from a material having a melting point higher than the melting point of the metal from which the component is to be formed. The sacrificial positive model is removed from the negative mould. Feed material (108) of metal powder is deployed into the mould and the metal powder is heated to a temperature higher than the melting point of the metal powder, so as to cause the metal powder to melt within the mould. |
