Excessive flow rates may decrease deposition efficiency due to particle collisions.
Achieved by mixing different particle sizes (e.g., trimodal distributions) to fill voids.
Increased feed rates (up to 40.2 g/min) can stabilize particle trajectories.
5 µm) have high cohesion forces, causing agglomeration and poor flow.
In additive manufacturing (3D printing) and powder metallurgy, the focus is on achieving and managing high flow dynamics . High Powder Flow Dynamics:
High powder properties typically refer to inhalation therapy or high flow rate additive manufacturing. In medical contexts, a high-dose powder is generally defined as one with a delivered dose of 1 mg or more . In manufacturing, "high powder" often relates to optimizing feed rates and bed densities for structural integrity. ⚕️ Pharmaceuticals: High-Dose Inhalable Powders
High-dose powders are critical for treating lung infections or systemic diseases where large amounts of medication must reach the deep lungs. Delivered doses ≥is greater than or equal to Challenges: Fine particles (
