Heat Source Modeling in Selective Laser Melting [PDF]

Materials, 2019
Selective laser melting is an emerging Additive Manufacturing (AM) technology for metals. Intricate three-dimensional parts can be generated from the powder bed by selectively melting the desired location of the powders. The process is repeated for each layer until the part is built. The necessary heat is provided by a laser.

Effects of Degree of Particle Melt and Crystallinity in SLS Nylon-12 Parts [PDF]

, 2008
Differential Scanning Calorimetry (DSC) traces for SLS Nylon-12 parts display two distinct melt peaks, which have been related to the presence of both melted and crystallised regions, and un-melted particle cores within the part.
