Rheological Behavior of Inconel 718 Powder for Electron-Beam Melting [PDF]
Metals, 2022 Understanding the impact of powder reuse in powder-bed-fusion electron beams (PBF-EB) is key to maintain the processability and yield. Powder oxidation, due to exposure to high temperatures for a prolonged period of time, can lead to a decrease in ...

, 2020 Laser Powder Bed Fusion (LPBF) is an additive manufacturing process for which one of the advantages is the possibility of reusing the non-fused powder. A high recovery rate can theoretically be achieved but this reuse methodology induces a gradual change in the powders characteristics with the risk of affecting the printed parts properties.

Ni Based Powder Reconditioning and Reuse for LMD Process
Physics Procedia, 2016 AbstractLMD is an additive manufacturing process based on the injection of metallic powder into a melt-pool created by a heat laser source on a substrate. One of the benefits of this technology is the reduction of the wasted material since it is a near-shape process.

Aging due to successive reuse of polyamide 12 powder during laser sintering: extrinsic powder properties and quality of sintered parts [PDF]
MATEC Web of Conferences, 2022 The effects of cumulative build time during the reuse of polyamide 12 (PA 12) for laser sintering (LS) on the morphology, size and shape distribution of the feedstock powder and quality of printed parts were investigated in this study.

Revealing the Effects of Powder Reuse for Selective Laser Melting by Powder Characterization [PDF]
JOM, 2019 In a selective laser melting process, it is common to reuse the powder in consecutive cycles of the route because it is more sustainable and cost effective. However, it is unknown whether reusing the material has an influence on the process. In this paper, Inconel 718, Ti6Al4V, AlSi10Mg and Scalmalloy are characterized to determine the impact of ...
