Nima E. Gorji,Prateek Saxena,Martin Corfield,Adam T. Clare,Jean-Pascal Rueff,J. Bogan,Pierre G.M. González,Matthew Snelgrove,G. Hughes,Robert O'Connor,Ramesh Raghavendra,Ramesh Raghavendra,Dermot C. Brabazon +12 more
TL;DR: In this paper, the pore formation in recycled powder particles of stainless steel 316L during the selective laser melting process was investigated using X-ray computed tomography (XCT).
Journal ArticleDOI
Comparison of the porosity and mechanical performance of 316L stainless steel manufactured on different laser powder bed fusion metal additive manufacturing machines
Muhannad Ahmed Obeidi,Sinéad M. Uí Mhurchadha,Ramesh Raghavendra,Ramesh Raghavendra,Alex Conway,Carlos Souto,David Tormey,Inam Ul Ahad,Dermot Brabazon +8 more
TL;DR: In this article, four different metal L-PBF printers were used to produce 316L tensile testing samples using the same processing parameters and metal powder supplied from a single batch from the same supplier.
Journal ArticleDOI
Experimental and empirical model analysis of microsurface texturing on 316 L press-fit joints fabricated by selective laser melting
Hamed Sohrabpoor,R. T. Mousavian,Sinéad O'Halloran,Khaled Y. Benyounis,Mohammad Baraheni,Muhannad Ahmed Obeidi,I. Ul Ahad,Ramesh Raghavendra,Ramesh Raghavendra,Dermot Brabazon +9 more
TL;DR: In this article, the accuracy of selective laser melting technique in fabrication of texture profile in shape, pitch and height of microsurface texturing was examined for the manufacturing of 316L stainless steel press-fit joints.
Journal ArticleDOI
316L Stainless Steel Powders for Additive Manufacturing: Relationships of Powder Rheology, Size, Size Distribution to Part Properties.
Robert Groarke,Cyril Danilenkoff,Sara Karam,Éanna McCarthy,Bastien Michel,Andre Mussatto,John Sloane,Aidan O' Neill,Ramesh Raghavendra,Ramesh Raghavendra,Dermot Brabazon +10 more
TL;DR: The results presented suggest that the powder properties strongly influence the powder rheology and are important factors in the selection of suitable powder for use in an additive manufacturing (AM) process.
A new method for assessing the utility of powder bed fusion (PBF) feedstock through life
