A 3D printing technique that deploys three lasers can create objects in just seconds, its designers claim. Traditional printers create objects by a time-consuming process of laying one microscopic layer or plastic over another. The new method uses the laser to melt and fuse together tiny droplets of liquid resin, which are then deposited onto an object using a sprayer. The technique also enables the creation of objects within other objects, a process impossible using traditional bottom-up or top-down printers.
A 3D printing technique that deploys three lasers can create objects in just seconds, its designers claim. Traditional printers create objects by a time-consuming process of laying one microscopic layer or plastic over another. Researchers at Lawrence Livermore National Laboratory in California, however, have created a device that shines three beams of light onto liquid resin and cures it at exact points. The technique also enables the creation of objects within other objects, a process impossible using traditional bottom-up or top-down printers.
