1. A method for manufacturing a solid, non-hollow metal based component comprising the steps of:
providing a plurality of metal based sheets;
arranging said plurality of metal based sheets in a stack, wherein said stack comprises a first metal based sheet, a last metal based sheet and at least one intermediate metal based sheet;
perimetrically sealing each sheet of the plurality of metal based sheets to at least another sheet of the plurality of metal based sheets, thereby forming at least one cavity inside of said stack;
removing gas from said at least one cavity;
subjecting said stack to a hot isostatic pressing process for a predetermined time at a predetermined pressure and a predetermined temperature, thereby closing the at least one cavity so that the plurality of metal based sheets of said stack bond metallurgically to each other and so that the entire stack of metal based sheets is solid and non-hollow, to thereby form the solid, non-hollow metal based component;
wherein said stack provides a passage at least partly defined by a surface of said at least one intermediate metal based sheet, such that said at least one cavity is fluidly connected to said first metal based sheet and is fluidly connected to said last metal based sheet.
