Description

In order to fabricate 3D complicated tissues and functional organs artificially, various manufacturing technologies have been developed in tissue engineering field, such as conventional scaffold based approaches, cell culture in designed molds, cell sheet technology that is the laminating of the cell sheets. Recently, cell spheroids and cell fibers have been produced by culturing cells in micro-scaled wells and by using micro fluidic devices fabricated by MEMS. Those are supposed to be useful biological parts to assemble large tissues. Such manufacturing-based approaches are called biofabrication, biomanufacturing and bioassembling. Among those promising technologies, in recent days, bio 3D printer has been focused most highly. It is because 3D printer technology has a big potential to position several biological materials including living cells precisely in 3D space based on the 3D CAD data, as the printing technologies have enabled to print several materials precisely in 2D. In this paper, we introduce several kinds of bio 3D printers.
