Abstract:
A method of manufacturing a turbo-machine impeller, which includes a hub and a plurality of blades, using powder material in an additive-manufacturing process. The method includes: applying energy to the powder material by way of a high energy source, and solidifying the powder material. At least one bulky portion of the hub is irradiated such that the powder material solidifies in a lattice structure surrounded by an outer solid skin structure enclosing the lattice structure.

Claim (Index 2):
The method according to  claim 1 , further comprising:\n depositing a first layer of powder material onto a target surface; irradiating a first portion of the first layer of powder material with the high energy source and solidifying the first portion of powder material, the first portion corresponding to a first cross-sectional region of the turbo-machine impeller; depositing a second layer of powder material onto the first portion; irradiating a second portion of said second layer of powder material with the high energy source and solidifying the second portion of powder material, the second portion corresponding to a second cross-sectional region of the turbo-machine impeller, the first portion and the second portion being joined to one another; depositing successive layers of powder material onto the previous portion and irradiating a portion of each successive layer to produce the turbo-machine impeller, further comprising a plurality of solidified, wherein each of the plurality of solidified layer portions correspond to a cross-sectional region of the turbo-machine impeller; wherein at least some of the successive solidified layer portions have at least one inner part formed by a lattice structure surrounded by an outer solid skin structure portion, the lattice structure forming at least the bulky portion of the impeller hub.
