3D printed micro-cyclones with improved geometries for low-cost aerosol size separation.

ABSTRACT: The impact of suspended particles on health, climate, and industrial applications is highly size-dependent. Thus, regulations are typically based on particles with diameters below a specific size, such as particulate matter less than 2.5 μm (PM_2.5). For over a century, cyclones have been employed to isolate particles below a certain diameter by removing large particles from a gas stream, but cyclones are typically relatively large, heavy, and expensive to fabricate compared to objects made with low-cost 3-dimensional (3D) printers. Herein, we present one-piece 3D-printed micro-cyclones (PM_2.5 and PM₁) to isolate particles smaller than a specific diameter. The collection efficiencies and 50% cut-off diameters (d₅₀) of multiple cyclones were evalua
