A new 3D-printing technique could render a three-dimensional object in minutes instead of hours—at up to 100 times current speeds. The experimental approach uses a vat of resin and some clever tricks with UV and blue LED lights (no lasers needed) to accelerate the printing process.

In a sense, Scott says, the new stereolithography process is really one of the very first truly 3D printing processes—in that it prints not just a series of single 2D layers but rather entire 3D wedges of material in one pass.

Scott says his group has been able to produce 2 meters of 3D-printed material per hour, contrasted to a typical 3D print speed for stereolithography in the range of 25 millimeters per hour.
[...] says that he’d like for some of his group's customers to have printed products in their hands by the end of this year or the beginning of next.
