A hybrid method of additive manufacturing is provided. The method includes providing a powder material and fusing, by a first heat source, a portion of the powder material to form a three-dimensional structure. The three-dimensional structure can define a fill region at least partially filled with the powder material. The method further includes fusing, by a second heat source, the powder material in the fill region. Fusing the powder material in the fill region can solidify the powder material in the fill region and fuse the powder material to the three-dimensional structure for forming a solid object.

A method of manufacturing a metal member including a first part and a second part includes a first fabrication process of fabricating the first part through a three-dimensional metal stack fabrication by a powder bed method, and a second fabrication process of fabricating an outer circumference of the second part through the three-dimensional metal stack fabrication by the powder bed method, and then sintering metallic powder remaining in an inner portion of the second part by hot isostatic pressing so as to fabricate the second part.

A method of additive manufacture involves building a container 8 and a structure by fusing powder 12, 13, 14, such that the container contains the structure and unfused powder. The container 8 may be used in a method for predicting powder degradation in an additive manufacturing process. Containers containing different types of structure may be built to measure the effect of building different types of structures on powder degradation. A structure to be built may be characterised by classes of structural features it contains and information obtained used from building containers used to predict how building the structure will degrade powder.

The invention relates to a method of high-throughput hot isostatic pressing micro-synthesis for the combinatorial materials and a sleeve mould thereof. The sleeve mould (2) comprises a honeycomb-array-sleeve (3) and an upper cover (4), wherein a plurality of single cells (6) are tightly arranged inside the honeycomb-array-sleeve (3), an exhaust tube (5) is arranged on the upper cover (4), after the single cells (6) are filled with powder materials, the upper cover (4) is sealed welding on the honeycomb-array-sleeve (3), and the honeycomb-array-sleeve (3) and the upper cover (4) are both integrally produced by additive manufacturing. According to the method and the sleeve mould, the powder metallurgy hot isostatic pressing process is utilized to prepare small-size bulk combinatorial materials with multiple discrete components rapidly at one time. This method has the characteristics of high sintering speed, high compaction density, good thermal diffusivity, short production cycle and low material consumption. This invention successfully overcomes drawbacks of current material preparation, such as unitary combination of components, huge material consumption and high cost.

A powder metallurgy method includes a canister that has canister walls that define a hermetic chamber that circumscribes an open central region. A metallic alloy powder is inserted into the hermetic chamber, followed by evacuating the hermetic chamber. The canister with the metallic alloy powder is then subjected to a hot isostatic pressing process that includes heating the canister and the metallic alloy powder and applying isostatic pressure to the canister. The heating and the isostatic pressure causes fusion and consolidation of the metallic alloy powder to form a solid workpiece. The canister is then removed from the solid workpiece
