Powder Analysis

Additive manufacturing processes enable the production of complex components with high precision. At the same time, they save material compared to machining processes. The quality of the materials used plays a critical role. The metal powders used have different properties, which have a direct influence on the processing, the results and therefore also on the reproducibility in additive manufacturing. Reproducibility is a major challenge in additive manufacturing.

Powder analysis helps to understand the causes and correlations between powder quality and process behavior and thus to optimize the additive components and coatings to the desired quality level. We can help you bring your additive components and coatings to the desired level.

The powder analysis provides an image of a powder particle (nickel-based alloy Inconel 718) with unfavorable morphology and satellites that restrict flowability.

What is powder analysis?

Steel alloys are used, for example, to coat brake disks.

Powder analysis, also known as powder characterization, is used to examine and classify metal powders for additive manufacturing. Powders are analyzed in detail for morphology, particle size distribution, flowability, and chemical specifications.

Currently, manufacturers are not required to provide information on the properties of the powders they produce. The analysis can help to detect discrepancies between the manufacturer's specifications and the powder samples. In this way, correlations between influencing factors and results can be understood and answers provided to problems such as binding errors, porosity, instabilities and variations.

 

Where can powder analysis help?

  • Poor powder flowability
  • Moisture
  • Inclusions and foreign atoms in the particle (e.g. from the manufacturing process)
  • Uneven particle size distribution (e.g., unwanted fine or coarse powder particles)
  • Many pores
  • Brittle particle morphology

 

What is powder analysis used for?

Anywhere metallic or non-metallic powders are used for additive manufacturing or coating. For example:
