| Abstract Scope |
Powder handling in binder jetting creates significant health and equipment hazards due to airborne dust, yet commercial sensors often lack the sampling frequency and data-logging flexibility required to monitor transient dispersion events. This paper presents the design and verification of a custom, low-cost (~$33), compact air particulate sensing system. Built using a PMS7003 laser diffraction sensor and an ESP32 microcontroller, the device monitors six particle size bins (0.3 to 10 µm) at a high sampling frequency of 0.8 Hz. Data is then logged directly to an onboard, removable microSD card in accessible formats for statistical analysis. Verification tests demonstrated high consistency between sensors, with a standard deviation of less than 6%. This scalable, open-source hardware approach provides a robust solution for quantifying powder dispersion and improving environmental safety monitoring in additive manufacturing facilities. |
