Reducing porosity in AlSi10Mg parts processed by selective laser melting
TL;DR: In this article, the windows of parameters required to produce high density parts from AlSi10Mg alloy using selective laser melting were investigated and a compromise between the different parameters and scan strategies was achieved and used to produce parts achieving a density of 99.8%.

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.
Journal ArticleDOI
Binding Mechanisms in Selective Laser Sintering and Selective Laser Melting
TL;DR: In this paper, a classification of SLS/SLM processes was developed, based on the binding mechanism occurring in the process, in contrast with traditional classifications based on processed material or the application.
