cylonlover writes "Three-dimensional printers are popping up everywhere these days. Some are small enough to fit in a briefcase and others are large enough to 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 scale. Now they're refining the technique to enable precise placement of 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."
