Bioprinting is an additive manufacturing process where biomaterials such as cells and growth factors are combined\u00a0to create tissue-like structures that imitate natural tissues.<\/p>\n
The technology uses a material known as\u00a0bioink<\/a>\u00a0to create these structures in a layer-by-layer manner.\u00a0The technique\u00a0is widely applicable to the fields of medicine and bioengineering.\u00a0Recently, the technology has even made advancements in the production of cartilage tissue for use in reconstruction and regeneration.<\/p>\n In essence, bioprinting works in a similar way to conventional 3D printing.\u00a0A digital model becomes a physical 3D object layer-by-layer. In this instance, however, a living cell suspension is utilized instead of a thermoplastic or a resin.<\/p>\n For this reason, in order to optimize cell viability and achieve a printing resolution adequate for a correct\u00a0cell-matrix\u00a0structure, it\u2019s necessary to maintain sterile printing conditions. This ensures\u00a0accuracy in complex tissues, requisite cell-to-cell distances,\u00a0and correct output.<\/p>\n The process principally involves preparation, printing, maturation, and application. This can be summarized\u00a0in the three key steps:<\/p>\n Several\u00a0bioprinting methods<\/a>\u00a0exist, based on either extrusion, inkjet, acoustic, or laser technologies. Despite the various types, a typical bioprinting process has a more-or-less standard series of steps:<\/p>\n The greatest importance of bioprinting lies in the resulting tissue-like structures that mimic the actual micro- and macro-environment of human tissues and organs. This is critical in drug testing and clinical trials,\u00a0with the potential, for example, to drastically reduce the need for animal trials.<\/p>\n When living tissues and organs need not come from humans, this budding technology offers other massive opportunities. One example is testing treatment for diseases using artificially affected tissues.<\/p>\n The process could also eradicate the headaches associated with organ donation and\u00a0transplantation.\u00a0Apart from the lack of available organs, the entire process\u00a0is criticized from a\u00a0moral and ethical perspective.<\/p>\n Organ replacement\u00a0is the main\u00a0objective, but tissue repair is also possible in the meantime. With bioink, it\u2019s much easier to solve problems on a patient-specific level, promoting simpler operations.<\/p>\n Here are a few of the main application areas of bioprinting:<\/p>\n\n
