  • Patent number: 11273595
    Abstract: A method of additive layer manufacture includes the steps of successively depositing layers of fusible powder material in overlying relationship and introducing energy, such as by an electron beam, into each deposited layer to selectively melt material in the layer so as to fuse the melted material together and to already fused material of a layer thereunder in order to produce a three-dimensional solid article in successive cross-sectional layers. In order to monitor layer quality, structured light defining a fringe pattern is projected onto each deposited layer before and/or after melting of material in that layer and the fringe pattern on each layer is imaged from a perspective different from that of the projection so as to reveal disturbance of the pattern by topographical features of the layer.

  • Patent number: 9248501
    Abstract: A powder consolidation method and apparatus make use of corrosion processes occurring on surfaces of metal particles to consolidate a metal-containing powder into a formed body. The method includes contacting metal particles with an acidic or basic liquid at a pH and potential at which dissolution of metal from the particles and reduction of soluble metal-containing ions to metal on surfaces of the particles can co-occur, such that the metal powder agglomerates to form a body.

  • Patent number: 9199309
    Abstract: A hot isostatic pressing tool includes a plurality of canister members and the hot isostatic pressing tool including at least one set of adjacent canister members. The plurality of canister members form a chamber to receive a powder material to be hot isostatically pressed. The at least one set of adjacent canister members have interlocking features forming a U-shaped, or a Z-shaped, leakage flow path between the at least one set of adjacent second canister members. The adjacent canister members are welded together to form a joint and the U-shaped, or Z-shaped, leakage flow path reduces the likelihood of failure of the welded joint during hot isostatic pressing.
