TL;DR: An overview of the state-of-the art of in-situ process monitoring in laser powder bed fusion processes and highlights some current limitations and areas for advancement is presented in this article.
Journal ArticleDOI
Influences of powder morphology and spreading parameters on the powder bed topography uniformity in powder bed fusion metal additive manufacturing
Andre Mussatto,Robert Groarke,Aidan O’Neill,Muhannad Ahmed Obeidi,Yan Delauré,Dermot Brabazon +5 more
TL;DR: In this article, the influence of particle morphology, spreading velocity and layer thickness on the powder bed topography uniformity has been investigated with a laser powder bed fusion printer and the powder layers were spread systematically and comprehensively.
Journal ArticleDOI
Laser Polishing of Additive Manufactured 316L Stainless Steel Synthesized by Selective Laser Melting
TL;DR: This study focuses on the laser surface polishing of AM parts using CO2 laser beam irradiation in continuous wave (CW) working mode and the characterization of the measured roughness and the modified layer microstructure was carried out using 3D optical and scanning electron microscopy.
Journal ArticleDOI

TL;DR: In this article, the 3D printing of NiTi shape memory alloy (SMA) in cuboidal shaped samples via the Laser Powder Bed Fusion (L-PBF) process using a dissimilar material build plate of 316L stainless steel.
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.
