Scientists at EPFL's Institute of Chemical Sciences and Engineering have created a unique way to improve the science of spectroscopy, using 3D printing to make specialized electrodes for manipulating and splitting light beams. With 3D printing and electroplating, these electrodes are both conductive and smooth. The team discovered they were able to use many of the benefits of 3D printing in this project as cost was low, productivity and speed increased exponentially, and workflow was completely digitalized.
