| Abstract Scope |
Airborne particulate dispersion and particle accumulation during binder jetting is measured to establish a predictive framework for safety and maintenance. Using custom air-monitoring sensors and passive deposition samples, mass distributions were characterized for powders of varying density. Results indicate that steady-state printing processes contribute >93% of cumulative dispersion, with over 75% of particulates falling within the PM2.5 category (<2.5 μm). A Gaussian elliptical dispersion model was developed to define spatial accumulation rates. The model achieves a strong fit without active air filtration (R˛ = 0.87-0.93), revealing that decay lengths in the recoater travel direction are up to 2.8 times greater than in transverse axes. Evaluation of air filtration showed a 96% reduction in airborne mass concentration. This research provides a framework for real-time monitoring and provides a strategy for assessing safety risks in printing new materials. |
