CFD Evaluation of Multi-Outlet Bioprinting Nozzles for Hydrogel Bioinks

A study presents computational fluid dynamics simulations comparing two multi-outlet nozzle designs for extrusion bioprinting. The data includes performance metrics like outlet flow balance and pressure-normalized throughput for GelMA, MeHA, and alginate bioinks. The work was authored by Cesar D. Vargas Urdaneta and last updated on 2026-04-17.

Use Cases

• Selecting nozzle architectures for cell safety based on simulated wall shear stress fields.
• Optimizing extrusion stability and deposition uniformity based on internal pressure and velocity fields.
• Comparing flow distribution performance between radial manifold and Y-split nozzle geometries.
• Defining safer operating windows for bioprinting based on pressure-normalized throughput metrics.

Strengths

• Simulations use representative rheological models for three common hydrogel bioinks: GelMA, MeHA, and alginate.
• The study provides a controlled comparison of two nozzle archetypes with two and four outlets.
• Performance metrics are derived from resolved 3D CFD fields for pressure, velocity, and wall shear stress.
• The dataset is openly licensed under CC-BY-4.0.

Limitations

• The primary data format is a PDF (155.4 KB), which likely contains textual and graphical results rather than raw simulation data.
• Row count and column-level documentation for any underlying numerical data are unknown.
• The dataset's small size suggests it may contain summary findings rather than extensive raw data tables.
