    Abstract: Method for fabricating a three-dimensional object by successive consolidation, layer by layer, of selected regions of a layer of powder, consolidated regions corresponding to successive sections of the three-dimensional object, comprising in order: a—deposit layer of powder onto a support; b—fuse the layer of powder by a first laser energy source so as to obtain a fused layer corresponding to the section of the object and exhibiting a first state of its mechanical properties, c—heat at least a part of the fused layer by a second electron beam energy source to a temperature which follows a controlled variation over time so as to modify the first state of the fused layer and to obtain a consolidated layer with improved mechanical properties, d—repeat the preceding steps until several superposed consolidated layers are formed with improved properties forming the object.

  • Publication number: 20150061188
    Abstract: A first die is filled with a mixed powder that is a mixture of a basic metal powder and a low-melting-point lubricant powder, the internal dimension of the first die being smaller than the internal dimension (=100%) of a second die by 1 to 5%. A first pressure is applied to the mixed powder in the first die to form a mixed powder intermediate compressed body. The mixed powder intermediate compressed body is heated to the melting point of the lubricant powder. A second pressure is applied to the heated mixed powder intermediate compressed body in the second die that has been pre-heated to the melting point of the lubricant powder to form a high-density mixed powder final compressed body.

  • Patent number: 8951466
    Abstract: Cam lobe packs and methods of producing the same. The method uses a tool made up of an insert disposed within a sleeve such that both are responsive to a dynamic magnetic compaction (DMC) pressure source. The insert defines a substantially axisymmetric exterior surface and a cam lobe-shaped interior surface that can receive a compactable material such that upon DMC, the material is formed into the shape of the cam lobe. The sleeve is disposed about the insert and defines a substantially axisymmetric exterior surface such that an axisymmetric compaction imparted to the sleeve by the DMC pressure source forms the desired shaped cam lobe. The tool is configured such that individual tool members corresponding to one or more of the cam lobes can be axially aligned so that an aggregate interior surface is formed that defines an exterior surface profile of a camshaft being formed.

  • Publication number: 20150024233
    Abstract: Methods and apparatuses to fabricate additive manufactured parts with in-process monitoring are described. As parts are formed layer-by-layer, a 3D measurement of each layer or layer group may be acquired. The acquisition of dimensional data may be performed at least partially in parallel with the formation of layers. The dimensional data may be accumulated until the part is fully formed, resulting in a part that was completely inspected as it was built. The as-built measurement data may be compared to the input geometrical description of the desired part shape. Where the part fails to meet tolerance, it may be amended during the build process or rejected.
