The accumulation of particles in the recirculation zone due to the presence of a structure resembling a vein valve over time. Valve structures with different photo-initiator (PI) mixing ratios (4%, 6%, and 8%) exhibited different stiffnesses. The degree of particle aggregation and valve stiffness was analyzed by measuring polystyrene particles in the recirculation zone around the valve.
