Abstract
A tool to differentially compress a powder material comprises a differential compression piston and a support. The piston comprises a first part configured to apply a pressure on a first region of an external surface of the powder material. The piston comprises a second part with a recess which is located at a lateral distance from the first part and which is configured to face a second region of the external surface of the powder material. The tool further comprises a membrane that can be deformed by the piston. The deformable membrane is configured to at least partially retain the powder material in the tool.
