A lab-on-a-chip is pretty self-explanatory: it's a miniature laboratory that is printed onto a microchip. But for the past 25 years, Professor David Barrow of Cardiff University in Wales has studied microfluidics, which is basically a small-scale plumbing system on a chip. Both of these tiny objects, which Professor Barrow has experience with, prove once again that bigger is not always better. Professor Barrow's research laboratory, where he studies the application of microfluidics (also called microreactors) in different fields, uses Ultimaker 3D printers to create necessary microfluidic devices, in order to keep costs down and continue developing different design iterations at a faster rate of speed. His research, and at what points 3D printing technology intersects with it, was recently detailed in an Ultimaker blog post.
