The invention relates to a sintered metal material comprising at least one magnetic part, characterised by directional through-pores having a size of between 1 and 100 μm, said material having a density varying by less than 20% from one sample of 1 cm3 to another taken from a one-piece part made from the material.

An inspection system for in situ evaluation of an additive manufacturing (AM) build part is provided. The inspection system comprises a build plane induction coil sensor configured and positionable so that during construction of the build part, the sensor's magnetization and sensor coils surround at least the last-produced layer of the AM build part in the build plane. The inspection system further comprises an energization circuit and a central processing system. The central processing system comprises a communication processor configured for sending command signals to the energization circuit and receiving impedance data from the build plane induction coil sensor, and energization controller configured for determining energization commands for transmission to the energization circuit, and an induction data analyzer configured for processing build part impedance data using complex impedance plane analysis and for identifying anomalies in the AM build part.

An isostatic pressing canister for use in manufacturing a component by isostatic pressing is described. The canister comprises: a canister wall enclosing an internal cavity, the canister wall having an internal surface facing the internal cavity; a filling point for filling the internal cavity with powdered material, the filling point comprising a hole in the canister; and a structure supported within the internal cavity and located between the hole and the portion of the internal surface opposite the hole. A portion of the internal surface of the canister wall opposite the hole is shaped so that, during the filling of the internal cavity, powdered material falling from the hole and towards the portion of the internal surface is deflected away from the portion of the internal surface. A method of manufacturing a component using the canister is also described.
