Learn more about the impact of temperature on powder cohesion thanks to the temperature control of the GranuDrum High Temperature instrument.
In this study, we suggest a method using powder flow characterization using the GranuDrum instrument to predict powder spreadability in additive manufacturing processes, such as SLM.
In this blog article, we explain what powder permeability is and its importance with the GranuPack Permeability.
We are thrilled to present the latest technical report in the field of additive manufacturing: ISO/ASTM TR 52952:2023 focusing on addressing a critical aspect of additive manufacturing: the characterization and optimization of metallic powders used in powder bed fusion and binder jetting processes.
In this article, we show how DEM simulations can help to better understand powder flow measurement and how to cross the bridge between the laboratory measurement and processes optimization in the production plant.

In powder bed based additive manufacturing processes, the need for a reproducible powder characterization method is very urgent. Learn in this blog article why the GranuDrum secures measurement reproducibility.
In the present study, the electrostatic charging of a metal powder during conveying through the different parts of a Laser Metal Deposition (LMD) machine has been investigated with the GranuCharge...
Each layer is then partially sintered or melted with an energy beam to build the parts. The layer thickness defines the vertical resolution of the printer; a thin layer leads to a better resolution...
Many industries are already using GranuTools instruments range in different fields: additive manufacturing, food processing, pharmaceuticals, bulk material handling. The present application note is mainly focused on additive manufacturing.
