Method for removal of support structures of additive manufactured components by pressurized jet

A method for manufacturing a vaned component of a turbomachine, the method comprising:

• providing a base portion, the base portion being part of the vaned component and serving as a starting point for manufacturing the vaned component;
• additively manufacturing, on top of the base portion, a plurality of vanes and a plurality of support structures, the plurality of support structures having predetermined breaking points;
• additively manufacturing, on top of the plurality of support structures and the vanes, a top portion being supported by the plurality of support structures, whereby the vanes are sandwiched between the base portion and the top portion;
• and
• applying a pressurized jet to the plurality of support structures, thereby breaking the predetermined breaking points of the plurality of support structures and removing the plurality of support structures, wherein applying the pressurized jet to the plurality of support structures comprises alternatingly applying the pressurized jet to an outer side that faces the pressurized jet and an inner side that faces the vanes of the vaned component of the plurality of support structures, thereby targeting the plurality of support structures at their outer side and at their inner side in an alternating manner.
