Cancer surgery is evolving quickly as researchers around the globe develop new techniques. The Lebanese University has created a robotic manipulator that precisely positions a laser used in photodynamic therapy. The laser activates drugs given to the patient, causing these photosensitizer drugs to activate and destroy cancerous growths. Researchers in Lebanon use National Instruments’ PCI-7334 to control the four stepper motors that move the laser head. Light must come from various angles to fully destroy the cancerous cells, so the head goes through many steps during the treatment.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
