3-D printing on the micrometer scale

Three-dimensional printers are popping up everywhere these days. Some are small enough to fit in a briefcaseand others are large enough to build print houses, but scientists at the Vienna University of Technology are going for the microscopic. Earlier this year, the university built a 3D printer that uses lasers to operate on a tiny small scale. Now they're refining the technique to enable precise placement a selected molecule in a three-dimensional material. This process, called “3D-photografting,” can potentially be used to create a “lab on a chip” or artificially grow living tissue... Continue Reading 3-D printing on the micrometer scale
