On the Temperature Distributions and Thermal Stresses Induced in Laser Solid Freeform Fabrication of Multi-material Structures

In many different multidisciplinary engineering applications such as biomedical applications inconsistent material properties are required in order to enhance mechanical properties and functionality of an object. Laser Solid Freeform Fabricationas, an additive manufacturing technique can be used to manufacture fully functional near-net-shape three dimensional objects directly from their CAD model by successive layer-by-layer deposition of metallic materials.
