... of a multichannel integrated nozzle to achieve a balanced trade-off between printing precision and cell viability. Design/methodology/approach A combined numerical simulation and experimental validation approach was used to compare different multichannel flow-channel geometries, with particular emphasis...

... and degradation rates of the bioink and cell viability. An experimental design was used to determine optimal parameters. The analyses included live/dead assays, rheological measurements, swelling and degradation. Findings The experimental design results showed that the hydrogel flow rate substantially...

... In designing the hybrid scaffolds, different unit cells were used such as dodecahedron (DCH), grid (G), octet-truss (OCT) with partially dense (PDsl) and fully dense (FDsl) surface layers. After fabrication of scaffolds on SLM machine, compression test and cell viability test were applied to observe the effect...
