Influence of particle size on powder rheology and effects on mass flow during directed energy deposition additive manufacturing

A. D. Iams et al.

Summary: Metal powders used in directed energy deposition additive manufacturing show variations in performance based on their particle characteristics and rheological properties, which affect powder flow and performance. The study found that lean grade stainless steel powder consistently displayed the lowest mass flow rates, indicating higher flow resistance due to a shift towards larger particle size distribution. Advanced powder and rheological characterization tools were necessary to identify differences between powders and understand their impact on flow behavior and performance.

Controlling factors determining flowability of powders for additive manufacturing: A combined experimental and simulation study

Yufan Zhao et al.

Summary: Powder flowability plays a crucial role in additive manufacturing, influenced by particle size distribution, particle morphology, and surface features. Experimental evaluation and numerical simulations on Inconel 718 alloy powders revealed that PREP powder exhibited the best flowability due to high particle sphericity and thin surface oxide film. Control of environmental factors during handling can lead to a natural advantage of PREP over GA and PA in terms of flowability.

Analysis of Spatter Removal by Sieving during a Powder-Bed Fusion Manufacturing Campaign in Grade 23 Titanium Alloy

Ryan Harkin et al.

Summary: The Laser-based Powder Bed Fusion (L-PBF) process involves selectively melting powder particles using a laser beam to manufacture components from CAD information. A sieving process is crucial in capturing spatter particles within the powder for further reuse. Analysis of Ti6Al4V (Grade 23) alloy powder after seven reuse iterations showed the characteristics of particles captured by the sieving process.

An improved Goldsmith-Cruz-Orive method for estimation of spherical size distribution from sectional size distribution, suitable for arbitrary size classes

Takao Ueda

Summary: The study developed an improved Goldsmith-Cruz-Orive method (ImpGCO) with configurable bins, and a simulator for spherical size distribution calculation. Results showed that when U-C was less than 3.5, neither GCO nor ImpGCO was recommended; in the U-C range of 3.5-6.5, ImpGCO performed better than GCO; and when U-C was greater than 6.5, both methods showed high performance, successfully eliminating at least 80% of bias.

Powder Reuse Cycles in Electron Beam Powder Bed Fusion-Variation of Powder Characteristics

Gitanjali Shanbhag et al.

Summary: In order to reduce the economic barrier associated with the high cost of metal additively manufactured components, it is important to focus on strategies like powder reuse and recycling. Systematic studies are needed to quantify the variation of powder properties induced by number of reuse cycles. Findings show that multiple reuse cycles and powder blends created from reused powder can lead to increases in various powder characteristics, with bulk density remaining largely unchanged.
