…print microstructures. "For the first time, researchers have shown that an optical fiber as thin as a human hair can be used to create microscopic structures with laser-based 3D printing. The innovative approach might one day be used with an endoscope to fabricate tiny biocompatible structures directly into tissue inside the body. This capability could enable new ways to repair tissue damage. "With further development our technique could enable endoscopic microfabrication tools that would be valuable during surgery," said research team leader Paul Delrot, from École Polytechnique Fédérale de Lausanne, Switzerland. "These tools could be used to print micro- or nano-scale 3D structures that facilitate the adhesion and growth of cells to create engineered tissue that restores damaged tissues."…."

Anyone care to explain what it means? Have not looked at the link, but a general idea would be helpful at a glance. Are the fibers used to be able to maneuver the print head easily, or as filament, or are they using the light from it in some way to make the actual print??? Other??? |

As no one else obviously knew what the article was about, I decided to have a look and try to decipher it for myself and other. However the link does not work. |

link A few links did not work, this one does. In a nut shell: Put end of ultra thin fiber optic in light sensitive liquid. Channel light through fiber. Light at tip of fiber solidifies tiny dot of the light sensitive liquid. Move fiber a bit, repeat…make a 3d structure of cured liquid. So they are using the light from the fiber optic to cure resin. Basically. I guess it avoids just passing light into the resin, which would solidify a rod sized amount, and, instead just focuses it on one internal point. Interesting. Hope this helps others. |
