Understanding the effects of metal powder feedstock heterogeneity on the laser powder bed fusion process

September 24, 2025

Author(s)

Aniruddha Das, Nicholas Derimow, Nikolas Hrabe, Jordan Weaver

Powder reuse is important to reduce the cost and improve the sustainability of laser powder bed fusion (PBF-LB) additive manufacturing. Several powder reuse strategies involve the blending of unused feedstock powder with used powder, which assume that the

Implementation of a Particle Tracking Method to Study Particle Spreading in Powder Bed Fusion Systems

Eric Whitenton, Alkan Donmez, Aniruddha Das, Vipin Tondare, Justin Whiting

Additive manufacturing is a rapidly growing and increasingly important set of manufacturing techniques. One of those techniques, powder bed fusion, is often used when making metal parts. The part is built up by spreading a thin layer of metal powder

Powder Spreading Testbed for Studying the Powder Spreading Process in Powder Bed Fusion Machines

November 29, 2023

Author(s)

Justin Whiting, Eric Whitenton, Aniruddha Das, Vipin Tondare, Jason Fox, Michael McGlauflin, Alkan Donmez, Shawn P. Moylan

The spreading of powder is an integral part of powder bed fusion-based additive manufacturing technologies; however, due to the complex nature and the number of interactions between particles, studying the powder spreading process is difficult. In order to

A Method for Capturing Thin Multi-Layer Regions of Powder from Powder Bed Fusion Machines

July 31, 2023

Author(s)

Aniruddha Das, Jordan Weaver, Jared Tarr, Shawn P. Moylan

A powder capture capsule has been designed to capture thin regions of powder at multiple heights within a powder bed of laser powder bed fusion (LPBF) equipment. This design is stackable, support free, and allows powder capture from a targeted region
