Controlled evaluation of multi-outlet nozzles affects flow balance in bioprinting, suggesting improved design approaches.

Assess how different multi-outlet nozzle geometries influence flow characteristics in bioprinting.
Conducted CFD simulations for various multi-outlet nozzle designs under specific conditions
Tested bioinks like GelMA, MeHA, and alginate with two archetypes: a radial 90° manifold and a Y-split
Analyzed flow distribution, shear stress, and throughput metrics.
The two-outlet 90° manifold showed the best flow uniformity and lowest shear exposure.
The two-outlet Y-split provided higher velocities but resulted in increased shear at junctions.
Increasing outlets to four led to flow maldistribution and didn't mitigate shear hotspots.
