Invetech, an innovator in new product development and custom automation for the biomedical, industrial and consumer markets, Dec 1, 2009 announced that it has delivered the world`s first production model 3D bio-printer to Organovo, developers of the proprietary NovoGen bioprinting technology. Organovo will supply the units to research institutions investigating human tissue repair and organ replacement.
Invetech plan to ship a number of 3D bio-printers to Organovo during 2010 and 2011 as a part of the instrument development program. Organovo will be placing the printers globally with researchers in centers of excellence for medical research.
“Scientists and engineers can use the 3D bio printers to enable placing cells of almost any type into a desired pattern in 3D,” said Murphy. “Researchers can place liver cells on a preformed scaffold, support kidney cells with a co-printed scaffold, or form adjacent layers of epithelial and stromal soft tissue that grow into a mature tooth. Ultimately the idea would be for surgeons to have tissue on demand for various uses, and the best way to do that is get a number of bio-printers into the hands of researchers and give them the ability to make three dimensional tissues on demand.”
The 3D bio-printers include an intuitive software interface that allows engineers to build a model of the tissue construct before the printer commences the physical constructions of the organs cell-by-cell using automated, laser-calibrated print heads.
The printer, developed by Invetech, fits inside a standard biosafety cabinet for sterile use. It includes two print heads, one for placing human cells, and the other for placing a hydrogel, scaffold, or support matrix. One of the most complex challenges in the development of the printer was being able to repeatedly position the capillary tip, attached to the print head, to within microns. This was essential to ensure that the cells are placed in exactly the right position. Invetech developed a computer controlled, laser-based calibration system to achieve the required repeatability.
