Atmospheric aerosol (AA) particles are defined as solid or liquid particles suspended in the air. AA particles smaller than 10 μm (1x10-5 meters) in diameter are small enough to bypass the upper respiratory system which functions as a filter for harmful substances entering the lungs. AA particles can be collected using a device called an aerosol impactor. After collection, the particles can be analyzed offline for chemical composition using a variety of analytical techniques. The weight of a commercially manufactured AA particle impactor poses an issue if it is attached to a mobile AA particle sampling platform such as an unmanned aerial vehicle (UAV). In this study a lightweight plastic AA impactor is designed and fabricated using Autodesk AutoCAD 2016 and a MakerBot Replicator 3-D printer. Project Motivation
