<br/><br/> 3D Bio-Printing is an advanced technology to fabricate scaffolds. Using this technique, the<br/>scaffolds of various tissues can be printed. A 3D Bio-Printer was designed for fabricating complex<br/>functional living tissues using bioink. Bioink is basically a blend of living cells along with<br/>biochemical materials including growth factors and support components and then printed. The<br/>factors to be considered during the development of a 3D Bio-Printer are compactness (To be placed<br/>in a laminar flow unit), Printing Resolution (Fabrication with high fidelity), Degree of freedom<br/>(Need multiple axes to print 3D construct), printing Speed (High speed required) and Process<br/>Biocompatibility. The aim of this research was to develop a syringe-based 3D Bio-Printer which<br/>may print Biomaterials and cells by considering these factors. The developed 3D Bio-Printer was<br/>then tested by printing a highly viscous hydrogel as proof-of-concept where gelatin was used to<br/>simulate the fluid properties of bioink. The syringe-based 3D Bio-Printer demonstrated a high level<br/>of printing resolution and stable prototype, and so has a potential for use in 3D cell culture after<br/>further in vitro testing
