Development of Physics-Based Numerical Models for Uncertainty Quantification of Selective Laser Melting Processes . Selective laser melting (SLM) is widely used in making three-dimensional functional parts layer by layer. However, due to the transient nature and small size of the molten pool, the temperature gradient and the molten pool size are very challenging to measure and control.

Selective laser melting (SLM) is a near-net-shape time- and cost-effective manufacturing technique, which can create strong and efficient components with potential applications in the aerospace industry. Introduction The process of selective laser melting (SLM) is very sensitive to the choice of the set of the numerous operating parameters as the laser power, the scanning velocity, the thickness of powder layer, and the hatch distance.

Selective laser melting additive technology method for material microstructure formation. Motivation / State of the Art Selective Laser Sintering/Melting (SLS/SLM) is a powder based Additive Manufacturing (AM) method that uses a laser to create three-dimensional parts by local sintering/melting of powder particles based on CAD data. Temperature magnitude and history during SLM directly determine the molten pool dimensions and surface integrity. Jean-Pierre Delplanque University of California, Davis.

"Mesoscale Multi-Physics Simulation of Solidification in Selective Laser Melting Process Using a Phase Field and Thermal Lattice Boltzmann Model." Selective laser melting is a relatively slow process when compared to traditional machining. Selective Laser Melting (SLM) is a particular rapid prototyping, 3D printing, or Additive Manufacturing (AM) technique designed to use high power-density laser to melt and fuse metallic powders.

A laser source selectively scans the powder bed according to the CAD data of the part to be produced.
