Enabling Progress in Space and defence

Modern rocket engines are now routinely manufactured using advanced 3D printing techniques, enabling optimal structural stability, reduced weight, and  integrated cooling channels  that were previously impossible to produce with conventional methods. This breakthrough in additive manufacturing has transformed the production of complex components such as missile parts and aircraft engine elements, where performance and reliability are paramount.

In these applications, metal powders—especially titanium and steel—play a critical role. For processes like 3D printing or thermal spray coating, the powders must exhibit tightly controlled particle size distributions to ensure consistent and reliable processing. Generally, spherical particles within a narrow size range are preferred, as they flow more easily and can be deposited more uniformly. However, if the size range is too narrow, packing density decreases, potentially leading to voids and inhomogeneities in the final component.

Microtrac  offers a comprehensive portfolio of technologies for analyzing particle size and shape, including both dry and wet dispersion methods. Their systems are designed to meet the stringent demands of aerospace and defense manufacturing. In this application note, Microtrac demonstrates how Dynamic Image Analysis (DIA) — as implemented in the CAMSIZER X2 - provides deep insight into powder quality. Unlike traditional sieving, DIA can detect even 0.005% of oversized particles, ensuring that only powders meeting the highest standards are used in production.
