description	Methods and apparatus for producing an object, the method comprising: performing an Additive Manufacturing process to produce an intermediate object from provided metal or alloy, whereby the intermediate object comprises regions having a contaminant concentration level above a threshold level; based upon one or more parameters, determining a temperature and a duration; and performing, on the intermediate object, a contaminant dispersion process by, for a duration that is greater than or equal to the determined duration, heating the intermediate object to a temperature that is greater than or equal to the determined temperature and less than the melting point of the metal or alloy, the contaminant dispersion process being performed so as to disperse, within the intermediate object, a contaminant from regions of high contaminant concentration to regions of low contaminant concentration until the intermediate object comprises no regions having a contaminant concentration level above the threshold level.
