  • Methods of manufacturing and cleaning
    Patent number: 10376932
    Abstract: Methods of cleaning internal portions of additively manufactured components are provided, together with an apparatus for carrying out the cleaning. The methods use an impacting element which is contained within the internal portion and the component is vibrated to clean material from the component and leave one or more hollow portions. Various embodiments for retaining the impacting element are set out, which preferably use a grid which allows loosened powder to fall out of the component and, optionally, be recycled for use in further manufacturing processes. The methods are described in relation to components for gas turbine engines but have wider application in relation to any additively manufactured component in which it is desired to have a hollow internal portion.
