Desktop 3D bioprinting: 3D bioprinting, a process similar to other additive manufacturing techniques, uses bioinks and biomaterials to create biomedical parts for research like skin tissue and organoids such as corneas. These printers have traditionally been voluminous, complicated, and costly. Allevi’s desktop 3D bioprinters are not only smaller, they are easy to use and significantly less expensive than larger models.
Bio-extrusion: A standard 3D printer at home or in a maker lab makes an object by adding material layer by layer. In bio-extrusion, bioinks are extruded from the nozzles and printed onto a biomaterial matrix.
Bioink: A material composed of living cells and biopolymer gels that, once extruded by the printer, can be organised into tissues, organs, and organoids.
Matrigel™: The trade name for the substrate used for culturing cells, essential in the bioprinting process as it is often the surface onto which the bioink is printed.
Angiogenesis: From ancient Greek, literally the creation (genesis) of vessels (angio). In modern biology, the term refers to the formation of new blood vessels within a tissue. In bioprinting, the presence of angiogenesis means that the printed tissue is behaving and growing in a way that is akin to living tissue and is essential to the success of creating functional printed tissues and organs.
Vascularization: Also related to the creation of blood vessels but, in contrast to angiogenesis, successful vascularization of a printed tissue is when an existing, printed structure of blood vessels is adopted by the tissue to delivering blood throughout the structure.
Innervation: The process by which a tissue is supplied with nerves. In 3D bioprinting, supplying a printed tissue with nerves is the latest frontier of the technology as supplying tissue not only with blood but also nerves could possibly accelerate restoration of muscle function in vivo and create more complex tissue models for research on neurological diseases.
