In this blog article, we explain what powder permeability is and its importance with the GranuPack Permeability.

In this article, we explain the importance of powder flow characterization for battery manufacturing using instruments such as the GranuDrum, the GranuCharge and the GranuPack.

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 the evaluation of granular segregation effect with powder characterization instruments such as the GranuPack and the GranuDrum.

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.

This article will explain the influence of grain size distribution on different powder properties.

This article explains why GranuHeap instrument is a real technological breakthrough in the measurement of the angle of repose to meet the requirements of modern industries.

This article explains how the Granucharge can be used to improve the processability of the powders

This article explains how to use GranuTools instruments to calibrate DEM simulations with a practical approach.

This article will explain how the rotating drum measurement and the GranuDrum can be used in the pharmaceutical industry. What are the benefits of using new methods and how would you know if one test is relevant or not.

Among these powder flow instruments, GranuTools has selected three configurations: the rotating drum (GranuDrum), the heap flow (GranuHeap) and the vertical-chute flow (GranuFlow). These particular geometries have been selected for two reasons.

In powder bed based 3D printers, the confining pressure is low, the flow speed is relatively high and the free powder/gas interface plays an important role...

Powder flow, also known as flowability, is defined as the relative movement of a bulk of particles among neighboring particles or along the container wall surface. In other words, powder flowability refers to the ability of a powder to flow in a desired manner in a specific piece of equipment...

The Additive Manufacturing (AM) is one of the remarkable recent technology in which a 3D object is produced by the layer-upon-layer method. This methodology is completely different than the conventional manufacturing techniques such as forging or casting from metal stock...

The initial and very basic requirement for the existing pharmaceutical and additive manufacturing (AM) industries are powders. Powder properties affect the packing dynamics/efficiency and flowability...

Packing of particles has application in various fields. Therefore, its study is of great importance...

The presence of electrostatic charges in powder induces adhesion and cohesion leading to intermittent or blocked flow and consequently non-uniformity of dosage.
Measuring the ability of a powder to charge during a flow was a challenge...

In Additive Manufacturing (AM) processes, a three-dimensional object is created one superfine layer at a time. Therefore, the term Additive Manufacturing implies adding material to create the object...

When a powder is poured onto a surface, a heap is formed. It is well known that both the repose angle and the heap shape strongly depend on grain properties (Moisture content, morphology, and particle size distribution, among other parameters, …).

A granular medium is an assembly of many solid elements, which can interact for example in collisions. But also under the effect of electromagnetic or gravitational forces...

Granutools is proud to introduce the revolutionary workflow for the process optimization of 3D printing. The workflow is essential for parts producers, 3D printer manufacturers and powder companies.

In SLS (selective laser sintering), SLM (selective laser melting) and EBM (electron beam melting) techniques, successive thin layers of powder are created with a ruler or with a rotating cylinder...
