Summary

Like 3D printing, 3D bioprinting is an additional fabrication technique that constructs an object, layer-by-layer, using a digital file as a template. Bioprinters, in contrast to 3D printers, use cells and biomaterials to create organ-like structures that allow living cells to multiply. Despite being relatively recent, bioprinting has the opportunity to solve several major deficiencies in medical research, including applications in drug discovery, regenerative therapy, functional tissue repair, and cosmetics screening. To produce the necessary tissue construct, a variety of materials, techniques, and cells can be used, depending on the application. In organ and tissue 3D bioprinting, cultured cells are combined with different biocompatible materials to make bioinks, which then can be 3D bioprinted into functional tissue constructs that need to be treated.
