BioBots offers a 3D bioprinter that is capable of printing in a variety of living tissue. So far it has been tested with over a dozen different cell types. It uses blue light and UV light to cure the extruded cell tissue, without harming or killing the cells. The company is currently offering a beta program, which comes with one of their bioprinters. The price is only $5,000, which is the cheapest I have seen a bioprinter sell for yet. They are hoping many researchers take them up on this offer in order to help advance the technology. They have even told me that normal Joe Schmo's can also join the program and begin printing scaffolds. Read and see more about this at: http://3dprint.com/19305/biobots-3d-bioprinter/
