We commonly use 3D printing in our lab for making (photo)electrochemical cells and reactors, and electrodeposition for depositing electrocatalytic materials.

Bridging both of these areas is a a recent paper in Energy & Environmental Science (EES) where researchers electroplated Nickel onto 3D printed PLA flow field plates to be used in polymer electrolyte membrane (PEM) electrolyzers:

Highlighting a commonly cited advantage of 3D printing, these researchers show the benefit of rapid prototyping that is made possible by 3D printing.
