3D printing has seen great advancements in various aspects over the past few decades, and many industries have seen innovative breakthroughs in their respective fields. Amongst them, the water treatment industry has also reaped benefits off the prospects of 3D printing. High performance spacers and membranes can be fabricated by 3D printing, and they help increase permeate production while minimising energy consumption in purification processes.
