Literature review: Methods for achieving high powder bed densities in ceramic powder bed based additive manufacturing

Open Ceramics, 2021
In additive manufacturing the powder bed based processes binder jetting and powder bed fusion are increasingly used also for the production of ceramics. Final part properties depend to a high percentage on the powder bed density. Therefore, the aim is to

Powders for powder bed fusion: a review [PDF]

Progress in Additive Manufacturing, 2019
The quality of powder used in powder bed-based additive manufacturing plays a key role concerning process performance and end part properties. Even though this is a generally accepted fact, there is still a lack of a comprehensive understanding of the powder property–part property relationship.

Laser Powder Bed Fusion of Chromium Bronze Using Recycled Powder [PDF]

Materials, 2021
Laser powder bed fusion (LPBF) of Cu-0.5Cr was carried out using recycled powder taken out from the LPBF machine after previous printing. Various volumetric defects characterized the powder wherein particle size distribution was the same as virgin powder. Using recycled powder resulted in extra spherical pore formation after the LPBF process.
