Rheological Behavior of Inconel 718 Powder for Electron-Beam Melting

open access: yesMetals, 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 ...

Coffee Powder Reused as a Composite Material [PDF]

open access: yes, 2017
With the technological and industrial development, many products have toxicity problems and the rate at which people consume new raw materials has become unsustainable. The markets have been undergoing changes and manufacturing materials tend to be more affordable, but they still have problems related with pollution and other ecological concerns.

Effect of powder reuse on physical, chemical and toxicological properties of 6061-Zr aluminum alloy processed by Laser Powder Bed Fusion (L-PBF)

open access: yesMatériaux & Techniques, 2023
Laser Powder Bed Fusion (L-PBF) is an additive manufacturing process, which allows to produce metallic parts layer by layer. The reuse of the powder is critical for cost part. The reuse can modify the powder and thus the printed parts properties.
