Determine grain structures in powders used in additive manufacturing, among others. The powder analysis features in VGSTUDIO MAX allow you to measure the form and size of powder particles individually, in specified groups, or in the complete powder sample and generate insightful statistics. Separate grains within powder or other granular materials to quantify them individually and determine important parameters, such as particle size, volume, surface, compactness, distributions of these parameters, and cleanliness of the powder feedstock.
With the powder analysis, you can:
*Porosity/Inclusion Analysis Module required
You can determine the following parameters for single grains using the powder analysis:
With a powder analysis, you can create 3D visualizations of the complete powder sample as well as of a single grain.
Create virtual 2D cross sections similar to a microscopic 2D powder characterization. For further analyses, you can export these 2D cross sections.
Plot powder features in a certain direction to investigate, among others, parts manufactured by binder jetting. In this case, the process-induced distribution of powder in the green part.
With the additional porosity/inclusion analysis module, you can also detect porosity within powder grains and impurities in the powder sample, such as inclusions of foreign material.
The distribution of the values of a corresponding grain parameter can be displayed using histograms. In the following example, which is a CT scan of a Ti6Al4V powder sample, the distribution of the equivalent diameters of the powder grains can be seen.
Via the X-Y-Plot, you can easily visualize dependencies between grain parameters. For example, the dependency between sphericity and equivalent diameter can be helpful in understanding progressive powder aging and evolving powder satellite formation.
