Spreading of highly cohesive metal powders with transverse oscillation kinematics
Reimar Weissbach, Garrett Adams, Patrick M. Praegla +2
Powder bed additive manufacturing processes such as laser powder bed fusion (LPBF) or binder jetting (BJ) benefit from using fine (D50 ) powders. However, the increasing…
Quantitative analysis of thin metal powder layers via transmission X-ray imaging and discrete element simulation: Blade-based spreading approaches
Ryan W. Penny, Daniel Oropeza, Patrick M. Praegla +4
Spreading uniform and dense layers is of paramount importance to creating high-quality components using powder bed additive manufacturing (AM). Blade-like tools are often employed…
Quantitative analysis of thin metal powder layers via transmission X-ray imaging and discrete element simulation: Roller-based spreading approaches
Ryan W. Penny, Daniel Oropeza, Reimar Weissbach +4
A variety of tools can be used for spreading metal, ceramic, and polymer feedstocks in powder bed additive manufacturing methods. Rollers are often employed when spreading powders…
Spatial Mapping of Powder Layer Density for Metal Additive Manufacturing via X-ray Microscopy
Ryan W. Penny, Patrick M. Praegla, Marvin Ochsenius +4
Uniform powder spreading is a requisite for creating consistent, high-quality components via powder bed additive manufacturing (AM), wherein layer density and uniformity are comple…
