Binder jetting is a rapidly growing form of additive manufacturing that relies on precise powder characteristics to achieve accurate part geometry, density, and strength. In this process, metal or ceramic powders are selectively bound layer by layer, making tight particle size distribution and flowability essential for repeatable, high-quality builds.
Traditional sieving methods often struggle to meet the demands of binder jetting due to intense screen mesh blinding, inconsistent particle separations, and electrostatic powder behavior. Elcan Industries’ Hi-Sifter high-energy screening machine technology provides an advanced solution for classifying binder jetting powders with exceptional precision and consistency, even at ultra-fine sizes down to 10 microns and in some cases 5um depending on the materials characteristics.
Binder jetting requires highly controlled particle size distributions, typically in the range of 15–53 microns or 20–63 microns, depending on the printer platform and application. These narrow ranges are essential for achieving optimal powder spreading, binder saturation, and part strength. Even minor variations in size can lead to defects, poor resolution, or inconsistent density. The Hi-Sifter offers a high-frequency, high-energy screening solution that eliminates screen blinding and delivers precise cut points, even for ultra-fine powders below 20 microns. This technology enables manufacturers to recover and reuse more material, reduce waste, and maintain consistency across multiple build cycles.
Elcan’s system also helps improve flowability and part repeatability, which are critical for binder jetting processes. Whether working with stainless steel, inconel, titanium, or ceramics, the Hi-Sifter ensures reliable separation and improved performance in additive manufacturing production environments.
