Laser additive manufacturing of metallic components: materials, processes and mechanisms
TL;DR: Additive manufacturing implies layer by layer shaping and consolidation of powder feedstock to arbitrary configurations, normally using a computer controlled laser as discussed by the authors, which is based on a novel materials incremental manufacturing philosophy.
Journal ArticleDOI
Consolidation phenomena in laser and powder-bed based layered manufacturing
TL;DR: In this article, the authors describe which types of laser-induced consolidation can be applied to what type of material, and demonstrate that although SLS/SLM can process polymers, metals, ceramics and composites, quite some limitations and problems cause the palette of applicable materials still to be limited.

Direct laser sintering of metal powders: Mechanism, kinetics and microstructural features
TL;DR: In this article, the densification and microstructural evolution during direct laser sintering of metal powders were studied, and it was found that when melting/solidification approach is the mechanism of sinter, the densifiers of metals powders (D ) can be expressed as an exponential function of laser specific energy input ( ψ ) as ln(1−− D )−= ǫ− Kψ.
