Continuous-Wave Diodes Shrink Size, Cost of 3D Laser ...
Compact desktop printers could soon take the place of big, expensive laser printers for printing 3D micro- and nanostructures. A two-step 3D-printing process, invented by researchers at Karlsruhe Institute of Technology (KIT) and Heidelberg University, works with blue laser diodes and can be implemented on small, inexpensive printers.
