    The BioPen Acts as Biological 3D Printing 3Doodler for Surgeons

    A tool developed by Australian researchers could completely change the way surgeons repair injuries and defects to cartilage and bone. The BioPen is essentially a biological 3Doodler - it allows surgeons to draw with a bioink directly onto the surface of a bone during surgery. The ink, comprised of stem cells in a hydrogel solution, would then multiply inside the body, growing into new tissue. So far, the pen has shown a more than 97% success rate in testing. Read more at

    It seems like this is only good for fixing small bits of cortical bone and maybe small skin repairs. Even simple skin grafts seem to require micro-structures to work properly.

    That said, this pen could free up a hospital's bioprinter from the simple prints that don't require them but still take a lot of time.
