...Ehsan Farabi; Mahyar Khorasani; Ahmad Mirzaei; Amir Hossein Ghasemi; Guy Littlefair; Eric MacDonald; Martin Leary; Ian Gibson; Stuart Bateman; Bernard Rolfe Purpose This study aims to introduce an algorithm that can successfully define optimum laser-based powder bed fusion (LB-PBF) processing...

...Patrick Beutler; Joël Roth; Mirko Meboldt Purpose Sacrificial supports are necessary for additive manufacturing ( AM ) technologies such as laser-based powder bed fusion with metals (PBF-LB/M) to produce defect-free parts. The production of supports increases production time and cost...

...Minting Wang; Renjie Cao; HuiChao Chang; Dong Liang Purpose Laser-based powder bed fusion (LPBF) is a new method for forming thin-walled parts, but large cooling rates and temperature gradients can lead to large residual stresses and deformations in the part. This study aims to reduce the residual...

... be applied to a very wide range of materials, with particular emphasis on metals. In this paper, the governing principles of both laser-based subtractive of metals (LB-SM) and laser-based powder bed fusion (LB-PBF) of metallic materials are discussed and evaluated in terms of performance and capabilities...

...Germán Omar Barrionuevo; Jorge Andrés Ramos-Grez; Magdalena Walczak; Xavier Sánchez-Sánchez; Carolina Guerra; Alexis Debut; Edison Haro Purpose The effect of processing parameters on the microstructure of steel produced by laser-based powder bed fusion (LPBF) is a recognized opportunity...

... bed fusion technique is limited, and has not been investigated yet. This paper aims to study the fabrication of AlSi₁₀Mg reinforced with nAl₂O₃ using the laser-based powder bed fusion technique. Design/methodology/approach An experimental approach was used...
