Powders are usefully thought of as bulk assemblies consisting of particles, (most usually) air and low levels of moisture. Particle properties often define critical aspects of product performance: the dissolution rate of a drug; catalytic activity; or the surface finish delivered by an abrasive.

Most methods of determining the particle size of powders are designed for off-line use [12]. The need for a fast, non-intrusive and inexpensive particle sizing tool suitable for the production line was the key reason for the development of an image-based system.

07/25 · Particle size and shape: To measure particle size and shape, the powders being examined were dispersed onto a sample plate using the dispersion unit integral to the image analysis system, and were then analysed according to standard operating procedures. Figure 1 shows examples of the captured images, and the size and shape parameters for the samples

Powder particle size distribution varied significantly within the powders used hence, because no systematic approach to powder distribution was adopted, conclusions on the effect of powder size distribution could not be drawn. It is clear that, as part of optimising a laser deposition application, powder size is one of the key variables.

However, the aluminum alloys process window is smaller than other AM alloys; therefore, the selection of the correct powder from the beginning of the production cycle is key to ensuring dependable properties. In this paper learn how the particle size distribution (PSD) cuts and the atomization process impact the quality of the powder.

Furthermore, that metal powder needs to spread evenly and consistently across the build platform 1000’s of times to ensure a uniform component. These two properties, packing density and powder flow, are controlled by particle size and shape which can be measured using laser diffraction and automated imaging.

Specifying metal powders. The common specifications of metal powders suitable for AM are the spherical geometry of the particles resulting from the gas atomisation and a particle size distribution according to the layer thickness, usually between 10-50 µm.
