3D Printing Helps Restore Man’s Face Following Accident

Welsh surgeons used 3D printing to reconstruct the badly injured face of a man injured in a motorcycle accident. They claim it is the first surgery in which 3D printing was used at every stage in the procedure. The 29-year-old man, despite wearing a helmet, had multiple facial fractures and a skull fracture in the 2012 accident. Surgeons at Morriston Hospital in Swansea, Wales—working with Cardiff Metropolitan University scientists—first used computed tomography scans and a 3D printer to create and print a symmetrical 3D model of the patient’s skull. They were then able to create precisely designed cutting guides and plates before beginning the eight-hour surgery.  (BBC)(AFP @ Yahoo! News)

UC Davis Start-Up Uses Silicon to Provide a Cheap Shave

A recently launched University of California, Davis start-up plans to use semiconductor-manufacturing technology to provide sharp, low-cost razor blades. Nano-Sharp Inc., which UC Davis researchers founded, plans to use silicon wafers that will enable them to make razor blades and surgical tools far more inexpensively than companies can manufacture conventional silicon or ceramic blades; however, they have not said precisely what it is about this process that makes the blades more affordable to manufacture. The process is being patented. The researchers stumbled across their approach while etching silicon wafers to be used as solar cells. The UC Davis technique creates blades across the surface of the wafer, where conventional methods create the blade by sharpening the edge of a silicon wafer. This new approach yields a sharpness close to that of diamond blades. The researchers say they could improve these blades’ performance by applying various semiconductor technologies. The University of California system recently gave them money so that they can develop a prototype to attract private investors.
