Enhancement of cell viability by fabrication of macroscopic 3D hydrogel scaffolds using an innovative cell-dispensing technique supplemented by preosteoblast-laden micro-beads.

•We propose a new cell-encapsulated dispensing method.•Fabrication was conducted using a three-axis robot system and an aerosol-spraying method.•The scaffold shows a realistic macroscopic pore-size and 100% pore-interconnected structure.•The use of micro-sized beads containing cells enhances cell viability in the dispensed 3D structure.
