Abstract:
1. A method of manufacturing a component, wherein the component comprises first and second layers, the first and/or second layers comprising one or more depressions provided on a surface of the respective layer, wherein the method comprises: arranging the first and second layers so that they face one another and with the depressions on inner facing surfaces of the layers; bonding the first and second layers together about their edges; applying a first differential pressure across each of the first and second layers to evacuate an inner space defined by the layers such that the layers are deformed with the depressions on the inner facing surface at least partially translated to an outer facing surface of the first or second layer, thereby forming one or more depressions on an outer facing surface of the first or second layer; and applying a second differential pressure across each of the first and second layers to inflate the inner space defined by the layers such that the layers are deformed with the depressions on the outer facing surface at least partially translated back to the inner facing surface of the first or second layer.
