Simple and Low Cost 3D Printed Exhalation Delivery System for Nasal Steroids (COSM 2026) - "Study Design: An experimental laboratory study was conducted to compare particle distribution characteristics of a 3D-printed exhalation delivery system with those of a commercial device (XHANCE delivery system, Optinose)... Fabrication of the device using a standard 3D printer can be achieved at nominal cost, and it is compatible with over-the-counter nasal steroid formulations. Collectively, this approach represents a potential avenue for substantial cost savings and improved accessibility. Future work will focus on adapting readily available household plumbing components to develop an even lower-cost version of the exhalation delivery system."
