... is at its minimum. However, the concentration of the laser energy in a small beam diameter requires many scan lines to expose components, resulting in comparatively low productivity. Therefore, this study aims to investigate whether systematic defocusing of the laser beam can improve build rates and, thus...

... the processing tool (point-to-point-, line- and mask-based) defining competitiveness. This study aims to define appropriate complexity indicators and evaluate the impact on productivity of PBF-LB/P (laser sintering). Design/methodology/approach An assessment methodology for geometric complexity is developed...

... are therefore focused on lowering costs by improving productivity while ensuring part quality. The purpose of this study is to quantify the productivity gains from using laser beam shaping, multi-laser printing and the use of large build chambers to print larger size parts. Design/methodology/approach...

...Sean McConnell; David Tanner; Kyriakos I. Kourousis Purpose Productivity is often cited as a key barrier to the adoption of metal laser-based powder bed fusion (ML-PBF) technology for mass production. Newer generations of this technology work to overcome this by introducing more lasers...

... activity-based production model. Design/methodology/approach Analysis tools that assess how design variables and process parameters influence production cost increase our understanding of the economics of AM, thereby supporting its practical adoption. To this aim, our framework produces...

...Wenbiao Han; Mohsen A. Jafari; Kian Seyed Compared to conventional manufacturing processes, fused deposition (FD)‐based layered manufacturing processes have dramatically reduced the part design and manufacturing time. However, it is necessary to further enhance their process productivity...
